Subject: [PATCH 001/571] [MTD] CHIPS: Recognize Spansion CFI 1.4 chips

Modify Amd/Fujitsu CFI NOR flash primary vendor extension table revision
check to recognize version 1.4.  Verified the existing driver can
handle version 1.4 chips without additional info from 1.4 extended table.

Move the primary vendor extension table revision check from common file
to the 3 CFI chip driver files, since the data structures and revisions
handled by those data structures are specific to the chip driver.

Modify the error message printed when the revision is unknown to be a
KERN_ERR instead of WARNING since this will cause mtd to ignore the chip.

Subject: [PATCH 003/571] [MTD] mtd_blkdevs.c: Fix names when many
 devices/partitions are created

mtdblock (and other mtd modules that use the mtd_blkdevs interface
between the mtd translation layers and the linux block layer) handles
incorrectly more than 10 devices or 26 partitions in the names passed to
the generic disk layer.  This causes the device file names and other
info kept by the generic disk/block layers to have names such as
"mtdblock<".  Use integer formatting for device numbers; use "aa-az"
for partitions 27-52, "ba-bz" for 53-78...

Subject: [PATCH 006/571] [CPUFREQ] Avoid the ondemand cpufreq governor to use
 a too high frequency for stats.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The problem is in the ondemand governor, there is a periodic measurement
of the CPU usage. This CPU usage is updated by the scheduler after every
tick (basically, by adding 1 either to "idle" or to "user" or to
"system"). So if the frequency of the governor is too high, the stat
will be meaningless (as mostly no number have changed).

So this patch checks that the measurements are separated by at least 10
ticks. It means that by default, stats will have about 5% error (20
ticks). Of course those numbers can be argued but, IMHO, they look sane.
The patch also includes a small clean-up to check more explictly the
result of the conversion from ns to µs being null.

Let's note that (on x86) this has never been really needed before 2.6.13
because HZ was always 1000. Now that HZ can be 100, some CPU might be
affected by this problem. For instance when HZ=100, the centrino ,which
has a 10µs transition latency, would lead to the governor allowing to
read stats every tick (10ms)!

Subject: [PATCH 007/571] [CPUFREQ] Remove preempt_disable from powernow-k8

Via reading the code, my understanding is that powernow-k8 uses
preempt_disable to ensure that driver->target doesn't migrate across cpus
whilst it's accessing per processor registers, however set_cpus_allowed
will provide this for us.  Additionally, remove schedule() calls from
set_cpus_allowed as set_cpus_allowed ensures that you're executing on the
target processor on return.

Subject: [PATCH 008/571] [AGPGART] Fix serverworks TLB flush. Go back to what
 2.4 kernels used to do here, as if this hits, the kernel just hangs
 indefinitly.

Actually an improvement over 2.4 - we now break; out of the loop
instead of just printing messages on timeouts.

Subject: [PATCH 012/571] [AGPGART] Set .owner field of struct pci_driver.

From: Laurent Riffard <laurent.riffard@free.fr>

This updates .owner field of struct pci_driver.

This allows SYSFS to create the symlink from the driver to the module which
provides it.

Subject: [PATCH 014/571] [IA64] Recent SPARSEMEM and DISCONTIG changes break
 some builds

My only objection to pfn_to_kaddr, which was introduced for HotPlug memory,
is that all arches have an identical implementation. I haven't had a chance
to pursue why yet.  There is probably some arch issue I'm unaware of.

Subject: [PATCH 025/571] [BLOCK] iosched: fix setting of default io scheduler

With the recent reorg of the io scheduler selection, it unfortunately
became possible to select an io scheduler to be the default even if it
wasn't builtin. Fix this by requiring the default scheduler to be
builtin.

Subject: [PATCH 031/571] [ALSA] usb-audio: simplify MIDI quirk handling

Modules: USB generic driver

Simplify the handling of MIDI quirks by treating an interface without
quirks as a QUIRK_MIDI_STANDARD_INTERFACE.

This also fixes the bug where a MIDI_STANDARD quirk would not be
recognized.

is always one where it matters, so we can just remove it.

Subject: [PATCH 044/571] [ALSA] Removing obsolete AC97_SHARED_TYPES

This patch cleans last ac97 audio/modem codec interception in
initialization procedures (ac97_mixer_new()) and removes obsolete
SHARED_TYPE 'locking' which prevents from AMC codecs to function
correctly.

Modules: Intel8x0 driver

On my Acer Aspire 3003LCi laptop, the speaker volume is not controlled
by the master control, but by the headphone control. Enabling the
'hp_only' quirk corrects this. The patch below adds this device to the
list of known quirks.

Subject: [PATCH 052/571] [ALSA] Remove snd_runtime_check() macro

Remove snd_runtime_check() macro.
This macro worsens the readability of codes.  They should be either
normal if() or removable asserts.

Also, the assert displays stack-dump, instead of only the last caller
pointer.

Subject: [PATCH 053/571] [ALSA] Use getnstimeofday()

Modules: Documentation,PCM Midlevel,Timer Midlevel,ALSA Core

Use the standard getnstimeofday() function instead of ALSA's own one.

-      <function>kfree_nocheck()</function> is used for that; it calls

Modules: ES1938 driver

This patch fixes the suspend/resume issue I'm having with ESS-Solo1
soundcard. Without this patch I might get after resume message
that kernel is disabling the IRQ5 (soundcard). If there was something
playing it wont continue after resume without this patch.

Subject: [PATCH 064/571] [ALSA] timers: add module refcounting for global
 timers

Modules: RTC timer driver,Timer Midlevel

Add a module pointer to the timer structure and use it for refcounting
instead of the card's module pointer to prevent the global timer
modules (rtctimer and hpetimer) from being removed while in use.

Subject: [PATCH 065/571] [ALSA] timer: remove list_entry() type casts

Modules: Timer Midlevel

The return value of list_entry() already has the type from the second
argument, so we don't need to typecase it again.

Subject: [PATCH 070/571] [ALSA] Reduce interrupt latency in
 sound/pci/via82xx.c

Modules: VIA82xx driver

The change only affects the via823x kind of chips.
Here the  via8233_pcm_pointer_hw() function
(named snd_via8233_pcm_pointer() before)
needed to loop until a non zero position is red from the chip.

Measurements have shown that more than 200 loops are typically needed on
an Athlon64.
As io-reads cost many cycles, those loops sum up huge.
via8233_pcm_pointer_hw() runs either in interrupt or with interrupts
disabled. So it introduces significant interrupt latency.

The patch introduces a calculated position value hwptr_done,
that is updated by the interrupt routine when a period is completed.
It is only used, if the 823x chip returns a zero position, which can't
be interpreted reliably.

Further optimisation is applied on the 8233 chip's interrupt routine:
Only the SGD_SHADOW is read, as it contains all infos needed.
We ommit ~5 more register reads that way.

Subject: [PATCH 073/571] [ALSA] seq-timer: restrict timer frequencies

Modules: ALSA sequencer

When no default timer frequency has been set, initialize_timer() just
uses the maximum frequency supported by the timer, which is ridiculously
high on 96 kHz timers.

This patch introduces a default frequency of 1000 Hz for this case, and
makes sure that a frequency set by the user isn't too high.

We better pretend that the ymfpci timer runs at 48 kHz because the
interrupt frequency cannot be higher, and clients that would try to
use 96 kHz would run at half their desired speed.

Subject: [PATCH 075/571] [ALSA] nm256: reset workaround for Latitude CSx

Modules: NM256 driver

The current snd-nm256 driver can cause Dell Latitude CSx laptops to
lock-up during module (un)load.  I have isolated this to the writes to
the control port register at offset 0x6cc which were not already
protected by the existing reset_workaround.

I tried grouping these writes with the existing reset_workaround
clause, but that caused the driver to have (un)load problems on the
Dell Latitude LS laptops.  So, I have implemented a reset_workaround_2
clause (please feel free to suggest a better name!) to cover this
situation and added a quirk entry for the CSx laptops.

Subject: [PATCH 086/571] [ALSA] Fix schedule_timeout usage

Use schedule_timeout_{,un}interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.  Also use
human-time conversion functions instead of hard-coded division to avoid
rounding issues.

Subject: [PATCH 093/571] [ALSA] AZT3328 driver update

Modules: AZT3328 driver

this is now an even much more reworked patch (#3) for my azt3328.c ALSA driver.
IOW I spent another 4 evenings to get the sequencer timer to work properly
(my head is still hurting) and do lots of other cleanups.

Note that despite the extensive sequencer timer additions, the driver object
is still only 2kB bigger than the previous version, due to those many
optimizations...

Changes in version #3:
- fully working ALSA sequencer timer support for the card's 1024000Hz
  DirectX timer (downscaling adjustable via seqtimer_scaling module param)
- an insane amount of code optimizations
- many, many cleanups

Changes in version #2:
- FOUND the 1us DirectX timer area (yay!), made the code respect it
properly
- renamed some 'weird' mixer control names according to ControlNames.txt
- cleanup unneeded debug messages, reformatting
- improved I/O register documentation
- constified many more structs

Changes in version #1:
- improves/fixes some fatal playback/recording interaction
- improves IRQ handler performance (and actually fixes some weird code)
- coalesces some I/O accesses
- slightly improves I/O interface documentation
- improves/fixes logging
- defines out some less important debug code
- constifies some data

Subject: [PATCH 094/571] [ALSA] emu10k1 - Use 31 bit DMA mask for Audigy

Modules: EMU10K1/EMU10K2 driver

It appears that either the Audigy DMA engine or the Linux kernel cannot
handle 32 bit DMA with this device.  Problem manifests as noise when
using more than 2GB of RAM, possibly only on 64 bit machines.

The OSS driver actually uses a 29 bit DMA mask for both devices, this
seems like overkill for now.

Subject: [PATCH 099/571] [ALSA] usb-audio: start submitting URBs in the
 prepared state

Modules: USB generic driver

If we submit all our URBs when a playback stream is started, the first
hwptr_done update for each URB happens at the same time.  This results
in an underrun when there isn't enough PCM data available at this
point for all URBs.

To avoid this, we begin submitting our URBs earlier (when the stream
is prepared), with empy packets.  When the stream is started, the
prepare_playback_urb() call for each URB will be run only when the
respective URB has completed previously, so the first hwptr_done
updates will be done nicely staggered.

Subject: [PATCH 107/571] [NETFILTER] PPTP helper: Fix endianness bug in GRE
 key / CallID NAT

This endianness bug slipped through while changing the 'gre.key' field in the
conntrack tuple from 32bit to 16bit.

None of my tests caught the problem, since the linux pptp client always has
'0' as call id / gre key.  Only windows clients actually trigger the bug.

Subject: [PATCH 108/571] [NETFILTER] NAT: Fix module refcount dropping too far

The unknown protocol is used as a fallback when a protocol isn't known.
Hence we cannot handle it failing, so don't set ".me".  It's OK, since we
only grab a reference from within the same module (iptable_nat.ko), so we
never take the module refcount from 0 to 1.

Also, remove the "protocol is NULL" test: it's never NULL.

We now reset the average queue length when setting new parameters, leaving
it might result in an unreasonable qavg for a while depending on the value of W.

+/*	Random Early Detection (RED) algorithm.
+	=======================================
+
+	Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways
+	for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking.
+
+	This file codes a "divisionless" version of RED algorithm
+	as written down in Fig.17 of the paper.
+
+	Short description.
+	------------------
+
+	When a new packet arrives we calculate the average queue length:
+
+	avg = (1-W)*avg + W*current_queue_len,
+
+	W is the filter time constant (chosen as 2^(-Wlog)), it controls
+	the inertia of the algorithm. To allow larger bursts, W should be
+	decreased.
+
+	if (avg > th_max) -> packet marked (dropped).
+	if (avg < th_min) -> packet passes.
+	if (th_min < avg < th_max) we calculate probability:
+
+	Pb = max_P * (avg - th_min)/(th_max-th_min)
+
+	and mark (drop) packet with this probability.
+	Pb changes from 0 (at avg==th_min) to max_P (avg==th_max).
+	max_P should be small (not 1), usually 0.01..0.02 is good value.
+
+	max_P is chosen as a number, so that max_P/(th_max-th_min)
+	is a negative power of two in order arithmetics to contain
+	only shifts.
+
+
+	Parameters, settable by user:
+	-----------------------------
+
+	qth_min		- bytes (should be < qth_max/2)
+	qth_max		- bytes (should be at least 2*qth_min and less limit)
+	Wlog	       	- bits (<32) log(1/W).
+	Plog	       	- bits (<32)
+
+	Plog is related to max_P by formula:
+
+	max_P = (qth_max-qth_min)/2^Plog;
+
+	F.e. if qth_max=128K and qth_min=32K, then Plog=22
+	corresponds to max_P=0.02
+
+	Scell_log

Subject: [PATCH 115/571] [NET]: Introduce INET_ECN_set_ce() function

Changes IP_ECN_set_ce() and IP6_ECN_set_ce() to return 0 if the CE
bits could not bet set because none of the ECT bits are set or 1
if the CE bits are already set or have been successfully set.

Introduces INET_ECN_set_ce(skb) to enable CE bits for all supported
protocols.

Simplifies code a lot by separating the red algorithm and the
queueing logic. We now differentiate between probability marks

backwards compatibility.

-	=======================================
-
-	Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways
-	for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking.
-
-	This file codes a "divisionless" version of RED algorithm
-	as written down in Fig.17 of the paper.
-
-Short description.
-------------------
-
-	When a new packet arrives we calculate the average queue length:
-
-	avg = (1-W)*avg + W*current_queue_len,
-
-	W is the filter time constant (chosen as 2^(-Wlog)), it controls
-	the inertia of the algorithm. To allow larger bursts, W should be
-	decreased.
-
-	if (avg > th_max) -> packet marked (dropped).
-	if (avg < th_min) -> packet passes.
-	if (th_min < avg < th_max) we calculate probability:
-
-	Pb = max_P * (avg - th_min)/(th_max-th_min)
-
-	and mark (drop) packet with this probability.
-	Pb changes from 0 (at avg==th_min) to max_P (avg==th_max).
-	max_P should be small (not 1), usually 0.01..0.02 is good value.
-
-	max_P is chosen as a number, so that max_P/(th_max-th_min)
-	is a negative power of two in order arithmetics to contain
-	only shifts.
-

Removes the skb trimming code which is not needed since we never
touch the skb upon failure. Removes unnecessary includes,
initializers, and simplifies the code a bit. Removes Jamal's
obsolete email addresses upon his own request.

Subject: [PATCH 120/571] [PKT_SCHED]: GRED: Cleanup equalize flag and add new
 WRED mode detection

Introduces a flags variable using bitops and transforms eqp to use
it. Converts the conditions of the form (wred && rio) to (wred)
since wred can only be enabled in rio mode anyway.

The patch also improves WRED mode detection. The current behaviour
does not allow WRED mode to be turned off again without removing
the whole qdisc first. The new algorithm checks each VQ against
each other looking for equal priorities every time a VQ is changed
or added. The performance is poor, O(n**2), but it's used only
during administrative tasks and the number of VQs is strictly
limited.

Subject: [PATCH 124/571] [PKT_SCHED]: GRED: Use a central table definition
 change procedure

Introduces a function gred_change_table_def() acting as a central
point to change the table definition.

Adds missing validations for table definition: MAX_DPs > DPs > 0
and def_DP < DPs thus fixing possible invalid memory reference
oopses. Only root could do it but having a typo crashing the
machine is a bit hard.

Adds missing locking while changing the table definition, the
operation of changing the number of DPs and removing shadowed VQs
may not be interrupted by a dequeue.

Subject: [PATCH 126/571] [PKT_SCHED]: GRED: Use central VQ change procedure

Introduces a function gred_change_vq() acting as a central point
to change VQ parameters. Fixes priority inheritance in rio mode
when the default DP equals 0. Adds proper locking during changes.

Subject: [PATCH 127/571] [PKT_SCHED]: GRED: Use new generic red interface

Simplifies code a lot by separating the red algorithm and the
queueing logic. We now differentiate between probability marks
and forced marks but sum them together again to not break
backwards compatibility.

This brings GRED back to the level of RED and improves the
accuracy of the averge queue length calculations when stab
suggests a zero shift.

Subject: [PATCH 128/571] [PKT_SCHED]: GRED: Do not reset statistics in
 gred_reset/gred_change

Qdiscs are not supposed to reset statistics in reset() and while
changing parameters. My argumentation is that if the user wants
the counters to be reset he can simply remove and readd the
qdiscs, that's what most users do anyway.

 messages

Try to enqueue packets if we cannot associate it with a VQ, this
basically means that the default VQ has not been set up yet.

We must check if the VQ still exists while requeueing, the VQ
might have been changed between dequeue and the requeue of the
underlying qdisc.

Subject: [PATCH 134/571] [PKT_SCHED]: GRED: Dont abuse default VQ for
 equalizing

Introduces a new red parameter set for use in equalize mode,
although only the qavg variable and the idle period marker are
being used for now this makes it possible to allow a separate
parameter set to be used for equalize later on.

The use of this separate parameter set fixes a bogus start of
an idle period in gred_drop() which did start an idle period
on the default VQ even if equalize mode was disabled.

Subject: [PATCH 135/571] [PKT_SCHED]: GRED: Remove auto-creation of default VQ

Since we are no longer depending on the default VQ to be always
allocated we can leave it up to the user to actually create it.
This gives the user the ability to leave it out on purpose and
enqueue packets directly to the device without applying the RED
algorithm.

Subject: [PATCH 139/571] [PKT_SCHED]: (G)RED: Introduce hard dropping

Introduces a new flag TC_RED_HARDDROP which specifies that if ECN
marking is enabled packets should still be dropped once the
average queue length exceeds the maximum threshold.

This _may_ help to avoid global synchronisation during small
bursts of peers advertising but not caring about ECN. Use this
option very carefully, it does more harm than good if
(qth_max - qth_min) does not cover at least two average burst
cycles.

The difference to the current behaviour, in which we'd run into
the hard queue limit, is that due to the low pass filter of RED
short bursts are less likely to cause a global synchronisation.

Subject: [PATCH 140/571] [NETEM]: Support time based reordering

Change netem to support packets getting reordered because of variations in
delay. Introduce a special case version of FIFO that queues packets in order
based on the netem delay.

Since netem is classful, those users that don't want jitter based reordering
can just insert a pfifo instead of the default.

This required changes to generic skbuff code to allow finer grain manipulation
of sk_buff_head.  Insertion into the middle and reverse walk.

Subject: [PATCH 142/571] [NET]: Fix race condition in sk_stream_wait_connect

When sk_stream_wait_connect detects a state transition to ESTABLISHED
or CLOSE_WAIT prior to it going to sleep, it will return without
calling finish_wait and decrementing sk_write_pending.

This may result in crashes and other unintended behaviour.

The fix is to always call finish_wait and update sk_write_pending since
it is safe to do so even if the wait entry is no longer on the queue.

This bug was tracked down with the help of Alex Sidorenko and the
fix is also based on his suggestion.

This patch randomizes the port selected on bind() for connections
to help with possible security attacks. It should also be faster
in most cases because there is no need for a global lock.

From 2b79adcca147c9f8fd1094ab4cb342d7e1790d70 Mon Sep 17 00:00:00 2001
From: "Artem B. Bityutskiy" <dedekind@infradead.org>
Date: Sun, 17 Jul 2005 12:13:51 +0100
Subject: [PATCH 147/571] [JFFS2] Use f->target instead of f->dents for symlink
 target

JFFS2 uses f->dents to store the pointer to the symlink target string (in case
the inode is symlink). This is somewhat ugly to use the same field for
different reasons. Introduce distinct field f->target for this purpose.
Note, f->fragtree, f->dents, f->target may probably be put in a union.

Subject: [PATCH 149/571] [JFFS2] Fix slab panic

When JFFS22 is unable to read the root inode, the bad root inode object is not
freed and remains sticked in the jffs2_i slab cache. When we further try to
free the slab cache (e.g., on rmmod jffs2), slab allocator subsystem panics.
Fix this bug.

Subject: [PATCH 165/571] {MTD] add support for Intel's "Sibley" flash

This updates the Primary Vendor-Specific Extended Query parsing to
version 1.4 in order to get the information about the Configurable
Programming Mode regions implemented in the Sibley flash, as well as
selecting the appropriate write command code.

This flash does not behave like traditional NOR flash when writing data.
While mtdblock should just work, further changes are needed for JFFS2 use.

The bit mask used for oob size calculation was using 2 bits instead
of one. Fortunately the next bit has been 0 all the time.

Thanks to Nathan H. for pointing this out

Subject: [PATCH 184/571] [JFFS2] Add erase block summary support (mount time
 improvement)

The goal of summary is to speed up the mount time. Erase block summary (EBS)
stores summary information at the end of every (closed) erase block. It is
no longer necessary to scan all nodes separetly (and read all pages of them)
just read this "small" summary, where every information is stored which is
needed at mount time.

This summary information is stored in a JFFS2_FEATURE_RWCOMPAT_DELETE. During
the mount process if there is no summary info the orignal scan process will
be executed. EBS works with NAND and NOR flashes, too.

There is a user space tool called sumtool to generate this summary
information for a JFFS2 image.

Subject: [PATCH 191/571] [JFFS2] Call summary collector for all mtd devices
 with writev support

Do the summary collection in the right place. If the device
was not writebuffered but had c->mtd->writev function
(e.g. blkmtd) the summary collector function was not called.

Subject: [PATCH 194/571] [MTD] NAND: Add suspend/resume functionality

The changes introduced allow to suspend/resume NAND flash.
A new state (FL_PM_SUSPENDED) is introduced, as well as
routines for mtd->suspend and mtd->resume to put the flash in
suspended state from software pov.

It did not cause problems, but the reservation code was unoptimal
when centralized summary was active or the size of the erase block
was very small.

+ - support asynchronous operation -- add a per-fs 'reserved_space' count,
+   let each outstanding write reserve the _maximum_ amount of physical
+   space it could take. Let GC flush the outstanding writes because the
+   reservations will necessarily be pessimistic. With this we could even
+   do shared writable mmap, if we can have a fs hook for do_wp_page() to
+   make the reservation.
  - disable compression in commit_write()?
  - fine-tune the allocation / GC thresholds
  - chattr support - turning on/off and tuning compression per-inode

  - NAND flash support:
-	- flush_wbuf using GC to fill it, don't just pad.
-	- Deal with write errors. Data don't get lost - we just have to write 
-	  the affected node(s) out again somewhere else.
-	- make fsync flush only if actually required
-	- make sys_sync() work.
-	- reboot notifier
-	- timed flush of old wbuf
-	- fix magical second arg of jffs2_flush_wbuf(). Split into two or more functions instead.
-
+	- almost done :)
+	- use bad block check instead of the hardwired byte check
 
  - Optimisations:
-   - Stop GC from decompressing and immediately recompressing nodes which could
-     just be copied intact. (We now keep track of REF_PRISTINE flag. Easy now.)
-   - Furthermore, in the case where it could be copied intact we don't even need
-     to call iget() for it -- if we use (raw_node_raw->flash_offset & 2) as a flag
-     to show a node can be copied intact and it's _not_ in icache, we could just do
-     it, fix up the next_in_ino list and move on. We would need a way to find out
-     _whether_ it's in icache though -- if it's in icache we also need to do the 
-     fragment lists, etc. P'raps a flag or pointer in the jffs2_inode_cache could
-     help. (We have half of this now.)
+   - Split writes so they go to two separate blocks rather than just c->nextblock.
+	By writing _new_ nodes to one block, and garbage-collected REF_PRISTINE
+	nodes to a different one, we can separate clean nodes from those which
+	are likely to become dirty, and end up with blocks which are each far
+	closer to 100% or 0% clean, hence speeding up later GC progress dramatically.
    - Stop keeping name in-core with struct jffs2_full_dirent. If we keep the hash in 
      the full dirent, we only need to go to the flash in lookup() when we think we've
      got a match, and in readdir().

Subject: [PATCH 216/571] [MTD] chips/cfi_cmdset_0001: fix for P30 cfi parsing

Change to the extended cfi table parsing for Intel NOR flash that uses
the info in the extended table to 'walk' the table rather than using
hard coding for various primary extended query table version numbers.

Subject: [PATCH 217/571] [MTD] NAND sharpsl.c: Add support for akita and
 borzoi models

The Sharp Zaurus akita and borzoi models are large page flash devices.
This patch adds support for them to the sharpsl MTD NAND driver but
keeps the oob layout and bad block positions compatible with the Sharp
Zaurus 2.4 kernel and ROM bootloader.

Nathan Roberts noticed the nand_write_ecc index into oobbuf goes out of
bounds when crossing an erase block boundary, causing incorrect OOB data
to be written and corrupting memory.  Reset the index to zero after
re-preparing oobbuf for a new erase block.

Subject: [PATCH 230/571] [MTD] chips cfi_cmdset_0002: Prevent timeout race

We've noticed that sometimes "MTD do_write_buffer(): software timeout"
message was printed out when writing to a Fujitsu NOR flash.
It turned out that this was because of a race in the timeout handling
do_write_buffer(). A small timeout of (HZ / 1000) + 1 is used there, and
sometimes if the timer interrupt handling takes more than one or even two
jiffies (which is 1-2 ms with HZ == 1000) and that interrupt happens just
after chip_ready() call, the driver bails out from a ready polling loop
despite the chip has actually become ready while all those interrupts were
handled. To deal with this issue, extra check for chip ready is neccessary on
timeout expiration (and the checks should better be reordered).
As do_write_oneword() uses the same approach, it needs to also be changed.

Subject: [PATCH 248/571] [PATCH] ppc64: Fix bug in SLB miss handler for
 hugepages

This patch, however, should be applied on top of the 64k-page-size patch to
fix some problems with hugepage (some pre-existing, another introduced by
this patch).

The patch fixes a bug in the SLB miss handler for hugepages on ppc64
introduced by the dynamic hugepage patch (commit id
c594adad5653491813959277fb87a2fef54c4e05) due to a misunderstanding of the
srd instruction's behaviour (mea culpa).  The problem arises when a 64-bit
process maps some hugepages in the low 4GB of the address space (unusual).
In this case, as well as the 256M segment in question being marked for
hugepages, other segments at 32G intervals will be incorrectly marked for
hugepages.

In the process, this patch tweaks the semantics of the hugepage bitmaps to
be more sensible.  Previously, an address below 4G was marked for hugepages
if the appropriate segment bit in the "low areas" bitmask was set *or* if
the low bit in the "high areas" bitmap was set (which would mark all
addresses below 1TB for hugepage).  With this patch, any given address is
governed by a single bitmap.  Addresses below 4GB are marked for hugepage
if and only if their bit is set in the "low areas" bitmap (256M
granularity).  Addresses between 4GB and 1TB are marked for hugepage iff
the low bit in the "high areas" bitmap is set.  Higher addresses are marked
for hugepage iff their bit in the "high areas" bitmap is set (1TB
granularity).

To avoid conflicts, this patch must be applied on top of BenH's pending
patch for 64k base page size [0].  As such, this patch also addresses a
hugepage problem introduced by that patch.  That patch allows hugepages of
1MB in size on hardware which supports it, however, that won't work when
using 4k pages (4 level pagetable), because in that case hugepage PTEs are
stored at the PMD level, and each PMD entry maps 2MB.  This patch simply
disallows hugepages in that case (we can do something cleverer to re-enable
them some other day).

Built, booted, and a handful of hugepage related tests passed on POWER5
LPAR (both ARCH=powerpc and ARCH=ppc64).

Subject: [PATCH 250/571] [PATCH] ia64: re-implement dma_get_cache_alignment to
 avoid EXPORT_SYMBOL

The current ia64 implementation of dma_get_cache_alignment does not work
for modules because it relies on a symbol which is not exported.  Direct
access to a global is a little ugly anyway, so this patch re-implements
dma_get_cache_alignment in a manner similar to what is currently used for
x86_64.

The zImage wrapper has a bug where it doesn't claim() the memory for the
kernel properly, it forgets to take into account the offset between the ELF
header and the kernel itself.  This results on some machines, like G5s,
into a kernel that crashes at boot when clearing the BSS.

Subject: [PATCH 256/571] [PATCH] slab: don't BUG on duplicated cache

slab presently goes BUG if someone tries to register an already-registered
cache.

But this can happen if the user accidentally loads a module which is already
statically linked into the kernel.  Nuking the kernel is rather a harsh
reaction.

Change it into a warning, and just fail the kmem_cache_alloc() attempt.  If
the module is well-behaved, the modprobe will fail and all is well.

Notes:

- Swaps the ranking of cache_chain_sem and lock_cpu_hotplug().  Doesn't seem
  important.

Subject: [PATCH 257/571] [PATCH] mm: rename kmem_cache_s to kmem_cache

This patch renames struct kmem_cache_s to kmem_cache so we can start using
it instead of kmem_cache_t typedef.

Subject: [PATCH 258/571] [PATCH] slab: Use same schedule timeout for all cpus
 in cache_reap

Chen noticed that cache_reap uses REAPTIMEOUT_CPUC+smp_processor_id() as
the timeout for rescheduling.

The "+smp_processor_id()" part is wrong, the timeout should be identical
for all cpus: start_cpu_timer already adds a cpu dependant offset to avoid
any clustering.

The attached patch removes smp_processor_id().

description for "global_options".

Subject: [PATCH 267/571] [PATCH] 3c59x: enable use of memory-mapped PCI I/O

Add capability for 3c59x driver to use memory-mapped PCI I/O resources.
This may improve performance for those devices so equipped.  This will be
the default behaviour for IS_CYCLONE and IS_TORNADO devices.  Additionally,
it can be enabled/disabled individually for up to MAX_UNITS number of
devices via the use_mmio module option or for all units via the
global_use_mmio option.  The use_mmio option overrides the global_use_mmio
option for those devices specified.

Subject: [PATCH 270/571] [PATCH] ppc32: Allow ERPN for early serial to depend
 on CPU type

The PowerPC 440SPe supports up to 16 GB of RAM, and therefore its IO registers
are at 0x4_xxxx_xxxx instead of being at 0x1_xxxx_xxxx like most other PPC 440
chips.  To allow for this, this patch moves the definition of the ERPN used
for mapping UART0 from being hard-coded in the head_44x.S assembly code to
being defined in ibm44x.h.

Subject: [PATCH 271/571] [PATCH] ppc32: Dump error status for both PLB
 segments on 440SP

The PowerPC 440SP SoC has two Processor Local Bus (PLB) segments (a
high-throughput segment and a low-latency segment).  Fix our PLB register
definitions to cope with this, and add code to dump the status of both
segments when a machine check occurs.

From 3e9e7c1d0b7a36fb8affb973a054c5098e27baa8 Mon Sep 17 00:00:00 2001
From: Matt Porter <mporter@kernel.crashing.org>
Date: Mon, 7 Nov 2005 00:58:15 -0800
Subject: [PATCH 274/571] [PATCH] ppc32: cleanup AMCC PPC40x eval boards to
 support U-Boot

Cleanup PPC40x eval boards (bubinga, walnut and sycamore) to support U-Boot
as bootloader.  The OpenBIOS bd_info struct is not used in the kernel
anymore (only U-Boot now).

uImage (U-Boot) tested on walnut, sycamore and bubinga
zImage (OpenBIOS) tested on sycamore, bubinga and ebony

Subject: [PATCH 275/571] [PATCH] ppc32: Remove internal PCI arbiter check on
 PPC40x

On PPC405GP/GPR it should be possible to enable PCI support, even when the
internal PCI arbiter is disabled (e.g.  when using an external PCI
arbiter).  The removed code didn't allow this, and also generated a warning
on PPC405EP platforms.

Subject: [PATCH 280/571] [PATCH] superhyway: multiple block support and VCR
 rework

This extends the API somewhat to allow for platform-specific VCR reading and
writing.  Some platforms (like SH4-202) implement the VCR in a split VCRL and
VCRH, but end up being in reverse order or have other quirks that need to be
dealt with, so we add a set of superhyway_ops per-bus to accomodate this.

We also have to extend the per-device resources somewhat, as some devices now
conveniently split control and data blocks.  So we allow a platform to
register its set of SuperHyway devices via superhyway_add_devices() with the
control block always ordered as the first resource (as this is the one that
userspace cares about).

Subject: [PATCH 281/571] [PATCH] sh: SuperHyway support for SH4-202

This adds support for the relatively quirky (ie, not in line with any known
documentation, and amazed it works at all) SuperHyway implementation on
SH4-202.  This depends on the earlier SuperHyway patch for multiple block
support and VCR refactoring.

Subject: [PATCH 282/571] [PATCH] sh: pte_mkhuge() compile fix for
 !CONFIG_HUGETLB_PAGE

Presently it is bogus to call pte_mkhuge() outside of the CONFIG_HUGETLB_PAGE
context, as the only processors that support _PAGE_SZHUGE do so in the
hugetlbpage context only (and this is the only time that _PAGE_SZHUGE is even
defined).  SH-2 and SH-3 do not support huge pages at all, and so it is not
possible to enable this.

Subject: [PATCH 283/571] [PATCH] sh: Drop hp690 discontig support

There was only one board using this (hp690 specifically), and it just so
happens that it's only physically discontiguous at the "normal" P1 offset.  If
we bump up the P1 offset, it's possible to hit a shadowed region of memory
where we suddenly become magically contiguous.

As people have been using this shadowed region workaround for quite some time
(and without any adverse effects), it's time to drop the left over discontig
bits that no longer have any practical use (it was always very much
hp690-centric to begin with).

Subject: [PATCH 284/571] [PATCH] sh: Use pfn_valid() for lazy dcache
 write-back on SH7705

SH7705 in extended cache mode has some left-over VALID_PAGE() cruft that it
checks when doing lazy dcache write-back.  This has been gone for some time
(the last bits were in the discontig code, which should now also be gone --
this also fixes up a build error in the non-discontig case).

pfn_valid() gives the desired behaviour, so we switch to that.

Subject: [PATCH 286/571] [PATCH] i386: LVT entries remaining unmasked on
 reboot

Excerpt from bugzilla entry

http://bugzilla.kernel.org/show_bug.cgi?id=5518

"i386 version of Reboot-through-BIOS is unsafe: it forgets to mask APIC LVT
interrupts before jumping to a BIOS entry point.  As a result, BIOS ends up
bombarded with interrupts early on boot.  The BIOS does not expect it since
following a "normal" hardware cpu reset, all APIC LVT registers have the
Mask bit (16) set and can't generate interrupts.

For example, the version of Phoenix BIOS used by VMware enables interrupts
for the first time before masking/clearing APIC LVT.  The APIC Timer LVT
register is still set up for a timer interrupt delivery with a high vector
from the previous Linux incarnation (0xef in our case).  The BIOS has not
fully initialized its IDT at this point and the real mode gate for 0xef
remains all zeros.  Vector 0xef dispatches BIOS to address 0:0, BIOS takes
a #GP and eventually hangs.

machine_shutdown() does attempt to shut down APIC before jumping to BIOS,
but it is ineffective"

Subject: [PATCH 290/571] [PATCH] cpu hoptlug: avoid usage of
 smp_processor_id() in preemptible code

Replace smp_processor_id() with any_online_cpu(cpu_online_map) in order to
avoid lots of "BUG: using smp_processor_id() in preemptible [00000001]
code:..." messages in case taking a cpu online fails.

All the traces start at the last notifier_call_chain(...) in kernel/cpu.c.
Since we hold the cpu_control semaphore it shouldn't be any problem to access
cpu_online_map.

The reason why cpu_up failed is simply that the cpu that was supposed to be
taken online wasn't even there.  That is because on s390 we never know when a
new cpu comes and therefore cpu_possible_map consists of only ones and doesn't
reflect reality.

printk() already declared in include/linux/kernel.h so squish the
duplication.  Besides, no printk() usage here.  Bye bye.

Subject: [PATCH 297/571] [PATCH] uml: improve stub debugging

Add some more debugging information when a stub does something unexpected,
usually segfaulting.  Now, it dumps out the stub's registers as well as the
signal.

Subject: [PATCH 298/571] [PATCH] uml: fix syscall stubs

Jeff Dike noted that the assembly code for syscall stubs is misassembled with
GCC 3.2.3: the values copied in registers weren't preserved between one asm()
and the following one.

So I fixed the thing by rewriting the __asm__ constraints more like unistd.h
ones.

Note: in syscall6 case I had to add one more instruction (i.e.  moving arg6 in
eax and shuffling things around) - it's needed for the function to be valid in
general (we can't load the value from the stack, relative to ebp, because we
change it), but could be avoided since we actually use a constant as param 6.

The only fix would be to turn stub_syscall6 to a macro and use a "i"
constraint for arg6 (i.e., specify it's a constant value).

Subject: [PATCH 299/571] [PATCH] uml: fix UML network driver endianness bugs

ifa->ifa_address and ifa->ifa_mask are defined as __u32, but used as if they
were char[4].

Network code uses htons() to convert it.  So UML's method to access these
fields is wrong for bigendians (e.g.  s390)

I replaced bytewise copying by memcpy(), maybe even that might be removed, if
ifa->ifa_address/mask may be used immediately.

Subject: [PATCH 303/571] [PATCH] uml: switch_mm fix

Not quite, something along the lines of the patch below works correctly (and
makes aio performance not suffer from multiple second delays), as skas0 mode
correctly switches mm contexts, unlike TT (which should probably get nuked
from the kernel now that skas0 seems to be working).

Subject: [PATCH 304/571] [PATCH] uml: maintain own LDT entries

Patch imlements full LDT handling in SKAS:
 * UML holds it's own LDT table, used to deliver data on
   modify_ldt(READ)
 * UML disables the default_ldt, inherited from the host (SKAS3)
   or resets LDT entries, set by host's clib and inherited in
   SKAS0
 * A new global variable skas_needs_stub is inserted, that
   can be used to decide, whether stub-pages must be supported
   or not.
 * Uses the syscall-stub to replace missing PTRACE_LDT (therefore,
   write_ldt_entry needs to be modified)

From ae17381608a11781a6a67e0ce51607f36780aac7 Mon Sep 17 00:00:00 2001
From: Jeff Dike <jdike@addtoit.com>
Date: Mon, 7 Nov 2005 00:58:57 -0800
Subject: [PATCH 305/571] [PATCH] uml: big memory fixes

A number of fixes to improve behavior when large physical memory sizes
are specified:

- libc files need -D_FILE_OFFSET_BITS=64 because there are unavoidable uses
  of non-64 interfaces in libc

- some %d need to be %u

Subject: [PATCH 307/571] [PATCH] uml: fix hardcoded ZONE_* constants in zone
 setup

Remove usage of hardcoded constants in paging_init().

By chance I spotted a bug in zones_setup involving a change to ZONE_*
constants, due to the ZONE_DMA32 patch from Andi Kleen (which is in -mm).
So, possibly, instead of zones_size[2] you will find zones_size[3] in the
code, but that change is wrong and this patch is still correct.

Subject: [PATCH 308/571] [PATCH] uml: build host-binaries with the native host
 arch again

This patch reverts back the changes to HOSTCFLAGS and HOSTLDFLAGS

When we were building complete binaries to get constants (such as ptrace
register layout on stack) from host userspace headers, we needed to make the
arch for building HOST binaries match our one: i.e.  on a 64bit system
compiling 32bit binaries, we compile 32-bit hostprogs and need, say, 32-bit
ncurses.  Now we can revert that - that avoids problem with, say, menuconfig
and ncurses, on a system which can't compile well 32-bit programs.

Subject: [PATCH 312/571] [PATCH] s390: stop_hz_timer vs. xtime updates

The calculation of the value return by next_timer_interrupt from jiffies to
jiffies_64 is racy against xtime updates.  We need to protect the calculation
with read_seqbegin/read_seqretry.

Subject: [PATCH 316/571] [PATCH] s390: remove pagex support

Remove pagex pseudo page fault code.  It does not work together with the
system call speedup that makes the complete system call path enabled for
interrupts.  To make pagex and the syscall speedup code work together we would
have to add code to the program check handler to do a critical section cleanup
like the asynchronous interrupt code.  This would make program checks slower.
Not what we want.

Newer versions of z/VM have the improved pfault pseudo page fault interface.
This replaces the old pagex interface and does not have the problem.  So its
better to just rip out the pagex code.

Subject: [PATCH 317/571] [PATCH] s390: test_bit return value

The test_bit function returns a non-boolean value, it returns 0,1,2,4,...
instead of only 0 or 1.  This causes wrongs results in the mincore system
call.  Check against 0 to get a proper boolean value.

Subject: [PATCH 318/571] [PATCH] s390: dasd diag inline assembly

Future versions of gcc may remove initialization code for control blocks used
by the diag250 inline assembly due to incompletely specified constraints.
This may lead to erratic behavior.  Fix the diag250 inline assembly
constraints.

Subject: [PATCH 319/571] [PATCH] s390: dasd diag with block sizes > 512

Access to FBA disks via DIAG fails for block sizes > 512 byte.  The device
analysis code of the DIAG discipline does not properly initialize the DIAG250
device environment after completion of the analysis.  This results in VM only
serving 512 bytes per block I/O request whereas Linux expects larger block
sizes.  Add proper device environment setup to end of analysis code.

Subject: [PATCH 322/571] [PATCH] s390: const pointer uaccess

Using __typeof__(*ptr) on a pointer to const makes the __x variable in
__get_user const as well.  The latest gcc will refuse to write to it.

 head64.S

Merge common parts of head.S and head64.S into head.S and move architecture
specific parts to head31.S and head64.S respectively.  Saves us ~500 lines
of duplicated assembly code.

- * There are 5 different IPL methods
- *  1) load the image directly into ram at address 0 and do an PSW restart
- *  2) linload will load the image from address 0x10000 to memory 0x10000
- *     and start the code thru LPSW 0x0008000080010000 (VM only, deprecated)
- *  3) generate the tape ipl header, store the generated image on a tape
- *     and ipl from it
- *     In case of SL tape you need to IPL 5 times to get past VOL1 etc
- *  4) generate the vm reader ipl header, move the generated image to the
- *     VM reader (use option NOH!) and do a ipl from reader (VM only)
- *  5) direct call of start by the SALIPL loader
- *  We use the cpuid to distinguish between VM and native ipl
- *  params for kernel are pushed to 0x10400 (see setup.h)
-
-    Changes: 
-    Okt 25 2000 <rvdheij@iae.nl>
-	added code to skip HDR and EOF to allow SL tape IPL (5 retries)
-	changed first CCW from rewind to backspace block

Subject: [PATCH 326/571] [PATCH] Move Kprobes and Oprofile to "Instrumentation
 Support" menu

Andrew Morton suggested to move kprobes from kernel hacking menu, since
kernel hacking menu is in-appropriate for the Kprobes.  This patch moves
Kprobes and Oprofile under instrumentation menu.

(akpm: it's not a natural fit, but things like djprobes and the s390 guys'
statistics library need a home)

Subject: [PATCH 327/571] [PATCH] write_inode_now(): write inode if not
 BDI_CAP_NO_WRITEBACK

If the backing_dev_info doesn't have BDI_CAP_NO_WRITEBACK we're not supposed
to write back an inode's pages.  But in this situation write_inode_now()
refuses to write the inode itself as well.  Fix.

Subject: [PATCH 328/571] [PATCH] Process Events Connector

This patch adds a connector that reports fork, exec, id change, and exit
events for all processes to userspace.  It replaces the fork_advisor patch
that ELSA is currently using.  Applications that may find these events
useful include accounting/auditing (e.g.  ELSA), system activity monitoring
(e.g.  top), security, and resource management (e.g.  CKRM).

Subject: [PATCH 329/571] [PATCH] Remove hlist_for_each_rcu() API, convert
 existing use to hlist_for_each_entry_rcu

Remove the hlist_for_each_rcu() API, which is used only in one place, and
is trivially converted to hlist_for_each_entry_rcu(), making the code
shorter and more readable.  Any out-of-tree uses may be similarly
converted.

This patch identifies the HPET Maintainers.  Clemens in taking over as
primary maintainer for the HPET driver.  Clemens has i386 hardware with
HPET and is a better choice than me because of this.  I've shared this
patch with all cc: recipients and there is agreement on ownership.
Hopefully this eliminates future confusion in terms of where HPET
maintenance is owned.

Subject: [PATCH 334/571] [PATCH] serial moxa: fix wrong BUG

There is a wrong BUG in mxser_close.

The BUG is triggered when tty->driver_data == NULL, But in fact this is not
a bug, because tty->driver->close is called even when tty->driver->open
fails.

LDD3 tells us to do nothing in such cases.

Subject: [PATCH 336/571] [PATCH] tpm: Fix lack of driver_unregister in init
 failcases

driver_unregister is not being properly called when the init function
returns an error case.  Restructured the return logic such that this and
the other cleanups all happen in one place.  Preformed many of the cleanups
that Andrew Morton's patch on Thursday made in tpm_atmel.c.  Fixed
Matthieu's concern about writing before discovery.

(akpm: rmk said:

This driver is buggy.  You must not provide your own release function - it
doesn't solve the problem which the warning (which you get when you don't
provide one) is telling you about.

You should convert your device driver over to the replacement dynamic platform
support, once it is merged.  IOW, something like:

	pdev = platform_device_alloc("mydev", id);
	if (pdev) {
		err = platform_device_add_resources(pdev, &resources,
						ARRAY_SIZE(resources));
		if (err == 0)
			err = platform_device_add_data(pdev, &platform_data,
						sizeof(platform_data));
		if (err == 0)
			err = platform_device_add(pdev);
		} else {
			err = -ENOMEM;
		}
		if (err)
			platform_device_put(pdev);
)

Subject: [PATCH 337/571] [PATCH] dell_rbu: Adding BIOS memory floor support

This patch has the changes to support the memory floor fix done in Dell
BIOS.  The BIOS incase of packet update mechanism would not accept packet
placed in memory below a cretain address.  This address is by default 128K
but can change.  The driver now can accept the memory floor if the user
chooses to make it will try to allocate contiguous physical memory above
the memory floor by allocating a set of packets till a valid memory
allocation is made.  All the allocates then are freed.  This repeats for
everty packet.

This patch was created by Michael E Brown and has been tested on 2.6.14-rc5

Subject: [PATCH 341/571] [PATCH] reiser4: add radix_tree_lookup_slot()

Reiser4 uses radix trees to solve a trouble reiser4_readdir has serving nfs
requests.

Unfortunately, radix tree api lacks an operation suitable for modifying
existing entry.  This patch adds radix_tree_lookup_slot which returns pointer
to found item within the tree.  That location can be then updated.

Both Nick and Christoph Lameter have patches which need this as well.

Subject: [PATCH 344/571] [PATCH] aio: remove aio_max_nr accounting race

AIO was adding a new context's max requests to the global total before
testing if that resulting total was over the global limit.  This let
innocent tasks get their new limit tested along with a racing guilty task
that was crossing the limit.  This serializes the _nr accounting with a
spinlock It also switches to using unsigned long for the global totals.
Individual contexts are still limited to an unsigned int's worth of
requests by the syscall interface.

The problem and fix were verified with a simple program that spun creating
and destroying a context while holding on to another long lived context.
Before the patch a task creating a tiny context could get a spurious EAGAIN
if it raced with a task creating a very large context that overran the
limit.

Subject: [PATCH 345/571] [PATCH] FUTEX_WAKE_OP: enhanced error handling

The code for FUTEX_WAKE_OP calls an arch callback,
futex_atomic_op_inuser().  That callback can return an error code, but
currently the caller assumes any error is EFAULT, and will try various
things to resolve the fault before eventually giving up with EFAULT
(regardless of the original error code).  This is not a theoretical case -
arch callbacks currently return -ENOSYS if the opcode they are given is
bogus.

This patch alters the code to detect non-EFAULT errors and return them
directly to the user.

Of course, whether -ENOSYS is the correct return value for the bogus opcode
case, or whether EINVAL would be more appropriate is another question.

There is a memory leak possible in dentry_open().  If get_empty_filp()
fails, then the references to dentry and mnt need to be released.  The
attached patch adds the calls to dput() and mntput() to release these two
references.

Subject: [PATCH 358/571] [PATCH] consolidate sys_ptrace()

The sys_ptrace boilerplate code (everything outside the big switch
statement for the arch-specific requests) is shared by most architectures.
This patch moves it to kernel/ptrace.c and leaves the arch-specific code as
arch_ptrace.

Some architectures have a too different ptrace so we have to exclude them.
They continue to keep their implementations.  For sh64 I had to add a
sh64_ptrace wrapper because it does some initialization on the first call.
For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but
SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.

From cc4e69dee4a080f6eae3f410daec2593f4fa6f00 Mon Sep 17 00:00:00 2001
From: Miklos Szeredi <miklos@szeredi.hu>
Date: Mon, 7 Nov 2005 00:59:49 -0800
Subject: [PATCH 359/571] [PATCH] VFS: pass file pointer to filesystem from
 ftruncate()

This patch extends the iattr structure with a file pointer memeber, and adds
an ATTR_FILE validity flag for this member.

This is set if do_truncate() is invoked from ftruncate() or from
do_coredump().

The change is source and binary compatible.

Though the following changes are all backward compatible (from the kernel's as
well as the library's POV) change the minor version, so interested
applications can detect new features.

Subject: [PATCH 361/571] [PATCH] FUSE: add access call

Add a new access call, which will only be called if ->permission is invoked
from sys_access().  In all other cases permission checking is delayed until
the actual filesystem operation.

Subject: [PATCH 362/571] [PATCH] FUSE: atomic create+open

This patch adds an atomic create+open operation.  This does not yet work if
the file type changes between lookup and create+open, but solves the
permission checking problems for the separte create and open methods.

Subject: [PATCH 363/571] [PATCH] FUSE: pass file handle in setattr

This patch passes the file handle supplied in iattr to userspace, in case the
->setattr() was invoked from sys_ftruncate().  This solves the permission
checking (or lack thereof) in ftruncate() for the class of filesystems served
by an unprivileged userspace process.

Date: Mon, 7 Nov 2005 00:59:53 -0800
Subject: [PATCH 364/571] [PATCH] as: cooperating processes

Introduce the notion of cooperating processes (those that submit requests
close to one another), and use these statistics to make better choices about
whether or not to do anticipatory waiting.

Help and analysis from Seetharami Seelam <seelam@cs.utep.edu>

Performance testing from Seelam:

I set up my system and executed a couple of tests that I used for OLS.  I
tested with AS, cooperative process patch merged in -mm tree (which I called
Nick, below) and the cooperative patch with modifications to as_update_iohist
(which I called Seelam).

I used a dual-processor (2.28GHz Pentium 4 Xeon) system, with 1 GB main memory
and 1 MB L2 cache, running Linux 2.6.9.  Only a single processor is used for
the experiments.  I used 7.2K RPM Maxtor 10GB drive configured with ext2 file
system.

Experiment 1 (ex1) consists of reading  one Linux source trees using

  find . -type f -exec cat '{}' ';' > /dev/null.

Experiment 2 (ex2) consists of reading two disjoint Linux source trees
using

  find . -type f -exec cat '{}' ';' > /dev/null.

Experiment 3 (ex3) consists of streaming read of a 2GB file in the background
and 1 instance of the chunk reads in Experiment 1.

Timings for reading the Linux source are shown below:

             AS                     Nick          Seelam
ex1:      0m25.813s               0m27.859s      0m27.640s
ex2:      1m11.468s               1m13.918s      1m5.869s
ex3:      81m44.352s             10m38.572s      6m47.994s

The difference between the numbers in Experiment 3 must be due to the code in
as_update_iohist.  (akpm: that's not part of this patch.  So this patch is
"Nick").

Subject: [PATCH 365/571] [PATCH] ipmi: use refcount in message handler

This patch is rather large, but it really can't be done in smaller chunks
easily and I believe it is an important change.  This has been out and tested
for a while in the latest IPMI driver release.  There are no functional
changes, just changes as necessary to convert the locking over (and a few
minor style updates).

The IPMI driver uses read/write locks to ensure that things exist while they
are in use.  This is bad from a number of points of view.  This patch removes
the rwlocks and uses refcounts and RCU lists to manage what the locks did.

From: Corey Minyard <minyard@acm.org>
Date: Mon, 7 Nov 2005 00:59:56 -0800
Subject: [PATCH 366/571] [PATCH] ipmi: various si cleanup

A number of small changes for the various system interface drivers,
consolidated from a number of patches from Matt Domsch.

Clear B2H_ATN and drain the BMC message buffer on command timeout.  This
prevents further commands from failing after a timeout.

Add bt_debug and smic_debug module parameters, expose them in sysfs.  This
lets you enable and disable debugging messages at runtime.

Unsigned jiffies math in ipmi_si_intf.c causes a too-large value to be passed
to ->event() after jiffies wrap-around.  The BT driver had caught this, but
didn't know how to fix it.  Now all calls to ->event() use a sane value for
time.

Increase timeout for commands handed to the BT driver from 2 seconds to 5
seconds.  This is necessary particularly when the previous command was a
"Clear SEL", as that command completes, yet the BMC isn't really ready to
handle another command yet.

Silence BT debugging messages which were being printed on the console.

Increase SMIC timeout form 1/10s to 2s.  This is needed on Dell PowerEdge 2650
and PowerEdge 750 with ERA/O cards to allow commands to complete without
timing out.

Adds kcs_debug module param, to match behavior of BT and SMIC.  This also
prevents messages from being sent to the console unless explicitly requested.

Subject: [PATCH 367/571] [PATCH] ipmi: watchdog parms in sysfs

Modify the IPMI watchdog parameters (the ones that make sense) to be exported
from sysfs.  This is somewhat complicated because these parameters have
side-effects that must be handled.

Subject: [PATCH 368/571] [PATCH] ipmi: poweroff cleanups

Make module_param and MODULE_PARAM_DESC agree on poweroff_powercycle name.

There was an extraneous ifdef in the IPMI poweroff code that prevented it from
working if PROC_FS was disabled.

Subject: [PATCH 369/571] [PATCH] ipmi: more dell fixes

Make SMIC driver ignore EVT_AVAIL and SMS_ATN bits in flags register, as
they're used by systems management interrupts, not the host OS.

Make the OEM0 Data Available handler work for pre-IPMI 1.5 systems from Dell
too.

Without these two fixes, PowerEdge 2650 and other similar systems with SMIC
may hang a process (modprobe or anything using /dev/ipmi0).

Subject: [PATCH 370/571] [PATCH] ipmi: si start transaction hook

Some commands, on some system BMCs, don't respond at at all.  This is seen on
Dell PowerEdge x6xx and x7xx systems with IPMI 1.0 BT controllers when a "Get
SDR" command is issued, with a length field of 0x3A, which happens to be the
length of about SDR entries.  If another length is passed, this command
succeeds.

This patch adds general infrastructure for receiving commands before they're
passed down to the low-level drivers, such that they can be completed
immediately, or modified, prior to being sent to ->start_transaction().

Subject: [PATCH 371/571] [PATCH] ipmi: bt restart reset fixes

The current BT retry/reset mechanism fails to succeed on a PowerEdge 1650,
when the controller is wedged with B2H_ATN asserted at XACTION_START.  If this
occurs, no further commands will ever succeed unless the state of the
controller is first cleared out.

Furthermore, the soft reset would only occur if the first command after insmod
was the one that timed out, not if a later command timed out.

This patch changes the retry/reset mechanism to be as follows:

Before retrying a command, clear the state of the BT controller such that the
flags represent ready for a new transaction.  This increases the chance of
success of the restarted transaction.

After 2 retries, issue a soft reset and retry one more time before giving up
and reporting back a failure.

Subject: [PATCH 372/571] [PATCH] ipmi: kcs error0 delay

BMCs can get into ERROR0 state while flashing new firmware, particularly while
the BMC is erasing the next flash block, which may take a just under 2 seconds
on a Dell PowerEdge 2800 (1.75 seconds typical), during which time the
single-threaded firmware may not be able to process new commands.  In
particular, clearing OBF may not take effect immediately.

We want it to delay in ERROR0 after clearing OBF a bit waiting for OBF to
actually be clear before proceeding.

This introduces a new return value from the LLDD's event loop,
SI_SM_CALL_WITH_TICK_DELAY.  This means the calling thread/timer should
schedule_timeout() at least 1 tick, rather than busy-wait.  This is a longer
delay than SI_SM_CALL_WITH_DELAY, which is typically a 250us busy-wait.

Subject: [PATCH 373/571] [PATCH] ipmi: add timer thread

We must poll for responses to commands when interrupts aren't in use.  The
default poll interval is based on using a kernel timer, which varies with HZ.
For character-based interfaces like KCS and SMIC though, that can be way too
slow (>15 minutes to flash a new firmware with KCS, >20 seconds to retrieve
the sensor list).

This creates a low-priority kernel thread to poll more often.  If the state
machine is idle, so is the kernel thread.  But if there's an active command,
it polls quite rapidly.  This decrease a firmware flash time from 15 minutes
to 1.5 minutes, and the sensor list time to 4.5 seconds, on a Dell PowerEdge
x8x system.

The timer-based polling remains, to ensure some amount of responsiveness even
under high user process CPU load.

Checking for a stopped timer at rmmod now uses atomics and del_timer_sync() to
ensure safe stoppage.

Subject: [PATCH 375/571] [PATCH] ipmi: use rcu lock for using command
 receivers

Use rcu_read_lock for the cmd_rcvrs list, since that was what what
intended, anyway.  This means that all the users of the cmd_rcvrs_lock are
tasks, so the irq disables are no longer required for that lock and it can
become a semaphore.

If a panic came from the IPMI watchdog pretimeout and that was reported via
an NMI, it would also be reported via the standard IPMI flags, which would
get picked up when reporting panic events and cause another panic.  This
adds an atomic to avoid calling panic twice.

Subject: [PATCH 377/571] [PATCH] Kprobes: rearrange preempt_disable/enable()
 calls

The following set of patches are aimed at improving kprobes scalability.  We
currently serialize kprobe registration, unregistration and handler execution
using a single spinlock - kprobe_lock.

With these changes, kprobe handlers can run without any locks held.  It also
allows for simultaneous kprobe handler executions on different processors as
we now track kprobe execution on a per processor basis.  It is now necessary
that the handlers be re-entrant since handlers can run concurrently on
multiple processors.

All changes have been tested on i386, ia64, ppc64 and x86_64, while sparc64
has been compile tested only.

The patches can be viewed as 3 logical chunks:

patch 1: 	Reorder preempt_(dis/en)able calls
patches 2-7: 	Introduce per_cpu data areas to track kprobe execution
patches 8-9: 	Use RCU to synchronize kprobe (un)registration and handler
		execution.

Thanks to Maneesh Soni, James Keniston and Anil Keshavamurthy for their
review and suggestions. Thanks again to Anil, Hien Nguyen and Kevin Stafford
for testing the patches.

This patch:

Reorder preempt_disable/enable() calls in arch kprobes files in preparation to
introduce locking changes.  No functional changes introduced by this patch.

 i386 changes

I386 changes to track kprobe execution on a per-cpu basis.  We now track the
kprobe state machine independently on each cpu, using an arch specific kprobe
control block.

Subject: [PATCH 382/571] [PATCH] Kprobes: Track kprobe on a per_cpu basis -
 sparc64 changes

Sparc64 changes to track kprobe execution on a per-cpu basis.  We now track
the kprobe state machine independently on each cpu using an arch specific
kprobe control block.

Subject: [PATCH 383/571] [PATCH] Kprobes: Track kprobe on a per_cpu basis -
 x86_64 changes

x86_64 changes to track kprobe execution on a per-cpu basis.  We now track the
kprobe state machine independently on each cpu using a arch specific kprobe
control block.

Subject: [PATCH 384/571] [PATCH] Kprobes: Use RCU for (un)register
 synchronization - base changes

Changes to the base kprobes infrastructure to use RCU for synchronization
during kprobe registration and unregistration.  These changes coupled with the
arch kprobe changes (next in series):

a. serialize registration and unregistration of kprobes.
b. enable lockless execution of handlers. Handlers can now run in parallel.

From 991a51d83a3d9bebfafdd1e692cf310899d60791 Mon Sep 17 00:00:00 2001
From: Ananth N Mavinakayanahalli <ananth@in.ibm.com>
Date: Mon, 7 Nov 2005 01:00:14 -0800
Subject: [PATCH 385/571] [PATCH] Kprobes: Use RCU for (un)register
 synchronization - arch changes

Changes to the arch kprobes infrastructure to take advantage of the locking
changes introduced by usage of RCU for synchronization.  All handlers are now
run without any locks held, so they have to be re-entrant or provide their own
synchronization.

From d217d5450f11d8c907c0458d175b0dc999b4d06d Mon Sep 17 00:00:00 2001
From: Ananth N Mavinakayanahalli <ananth@in.ibm.com>
Date: Mon, 7 Nov 2005 01:00:14 -0800
Subject: [PATCH 386/571] [PATCH] Kprobes: preempt_disable/enable()
 simplification

Reorganize the preempt_disable/enable calls to eliminate the extra preempt
depth.  Changes based on Paul McKenney's review suggestions for the kprobes
RCU changeset.

Subject: [PATCH 387/571] [PATCH] RapidIO support: core base

Adds a RapidIO subsystem to the kernel.  RIO is a switched fabric interconnect
used in higher-end embedded applications.  The curious can look at the specs
over at http://www.rapidio.org

The core code implements enumeration/discovery, management of
devices/resources, and interfaces for RIO drivers.

There's a lot more to do to take advantages of all the hardware features.
However, this should provide a good base for folks with RIO hardware to start
contributing.

Subject: [PATCH 394/571] [PATCH] prevent dmesg warning in zr36067 driver

Fix the warning "Debug: sleeping function called from invalid context at
include/asm/semaphore.h:102" that the zr36067 driver emits every time an
application using JPEG capture starts up (e.g.  mjpegtools' lavrec).

The warning is harmless, but clogs up the dmesg output.  This was logged as
bugzilla #5403.  (Thanks to Christian Casteyde for helping me in fixing
this long-standing annoyance.)

Subject: [PATCH 395/571] [PATCH] knfsd: fix setattr-on-symlink error return

This is a somewhat cosmetic fix to keep the SpecFS validation test from
complaining.

SpecFS want's to try chmod on symlinks, and ext3 and reiser (at least) return
ENOTSUPP.

Probably both sides are being silly, but it is easiest to simply make it a
non-issue and filter out chmod requests on symlinks at the nfsd level.

Subject: [PATCH 396/571] [PATCH] knfsd: Restore functionality to read from
 file in /proc/fs/nfsd/

Most files in the nfsd filesystems are transaction files.  You write a
request, and read a response.

For some (e.g.  'threads') it makes sense to just be able to read and get the
current value.

This functionality did exist but was broken recently when someone modified
nfsctl.c without going through the maintainer.  This patch fixes the
regression.

Subject: [PATCH 398/571] [PATCH] knfsd: Fix some minor sign problems in
 nfsd/xdr

There are a couple of tests which could possibly be confused by extremely
large numbers appearing in 'xdr' packets.  I think the closest to an exploit
you could get would be writing random data from a free page into a file - i.e.
 leak data out of kernel space.

I'm fairly sure they cannot be used for remote compromise.

Subject: [PATCH 399/571] [PATCH] knfsd: make sure svc_process call the correct
 pg_authenticate for multi-service port

If an RPC socket is serving multiple programs, then the pg_authenticate of
the first program in the list is called, instead of pg_authenticate for the
program to be run.

This does not cause a problem with any programs in the current kernel, but
could confuse future code.

Also set pg_authenticate for nfsd_acl_program incase it ever gets used.

Subject: [PATCH 402/571] [PATCH] nvidiafb: Fix mode setting & PPC support

This patch fixes nvifiafb mode setting code to be closer to what the X
driver does, which actually makes it work on the 5200FX I have access to.
It also fix the routine that gets the EDID from Open Firmware on PPC, it
was broken in various ways and would crash at boot.  Compared to the patch
I posted to linux-fbdev last week, this one just changes a printk to be
closer to the other ones in the driver.

Subject: [PATCH 404/571] [PATCH] nvidiafb: Add flat panel dither support

nvidiafb didn't fully hook-up the code it borrowed from X for doing flat
panel dithering (this is useful for 6 bits panels).  This adds a driver
option to force it, and by default "reads" the current value from the chip
to get the firmware setting.  It significantly improves the quality of
images on the iMac G5 I have here (though the X driver doesn't yet "read"
the current value and defaults to 0, so you have to add Option "FBDither"
"true" to your X config file to get that, I'll try to fix X.org to "read"
the default unless specified asap).

Subject: [PATCH 407/571] [PATCH] fbcon/fbdev: Move softcursor out of fbdev to
 fbcon

According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant.  The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit.  And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.

Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank.  For drivers that do, they can fill up this field with their own
version.

The end result is a smaller code size.  And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.

Subject: [PATCH 410/571] [PATCH] fbcon: Initialize new driver when old driver
 is released

If machine has more than 1 driver installed, and they all drive the same
hardware, it's possible that the driver's fb_release() method will attempt to
restore the hardware state to the initial state.  This will leave the new
driver in an undefined state.  To prevent this problem, initialize the new
driver by calling fb_set_par() when the old driver is released by fbcon.

 functions

Remove software clipping from imageblit, fillrect and copyarea.  Clipping is
not needed because the console layer assures that reads/writes doest not
happen beyond the extents of the framebuffer.  And software clipping tends to
hide bugs, if they do exist.

Fix out-of-bounds bug.  The pseudopalette has room only for 16 entries, thus,
write only the first 16 entries to the pseudopalette.

Subject: [PATCH 413/571] [PATCH] atyfb: Get initial mode timings from LCD BIOS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Reported by: Jean-Philippe Guérard (Bugzilla Bug 1782)

"I've tried with video=atyfb:debug and video=atyfb:debug,mode:1280x600, \
nomtrr.

In both case, the screen stays black, but seems divided into 4 vertical bands.
 Some white lines pop up randomly on each vertical band."

The problem is a combination of an incorrect xclk plus lack of timing
information.  The adapter is attached to an LCD device that can do 1280x600
(which is not a standard resolution).  The global mode database does not have
an entry for it.  Fortunately, the Video BIOS contains the complete timing
info for this display, however, atyfb is not making use of it.

Add support to get the timing information from the BIOS, if available.

Subject: [PATCH 415/571] [PATCH] pm2fb: Manual configuration of timings for
 Elsa Winner 2000 Office

Attached is a small patch which configures the correct memory clock and
timings on the Elsa Winner 2000 Office pm2 based card.  This is necessary when
the card is used on a platform which does not support PC style BIOS
initialization.

detailed timings.

Subject: [PATCH 418/571] [PATCH] fbdev: fix the fb_find_nearest_mode()
 function

Currently the fb_find_nearest_mode() function finds a mode with screen
resolution closest to that described by the 'var' argument and with some
arbitrary refresh rate (eg.  in the following sequence of refresh rates: 70 60
53 85 75, 53 is selected).

This patch fixes the function so that it looks for the closest mode as far as
both resolution and refresh rate are concerned.  The function's first argument
is changed to fb_videomode so that the refresh rate can be specified by the
caller, as fb_var_screeninfo doesn't have any fields that could directly hold
this data.

vesafb occassionally gets the size wrong when setting the mtrr.  When X or DRI
attempts to set the mtrr, it will fail due to range overlap significantly
affecting their performance.  Disable mtrr and let the user explicitly enable
it with the mtrr:n option.

- The functions for reading the 1st and 2nd bus are essentially the same,
  except for the register.  Consolidate them all.

- According to Nicolas Boichat, there is an undocumented 3rd i2c bus for
  attaching daughter cards.  Add support for this.

Subject: [PATCH 423/571] [PATCH] fbcon: Add rl (Roman Large) font

I converted the "rl" console font from the kbd utility to be a built-in font
for the framebuffer console, and I was wondering if you would be OK with
including it.  I've generated a font_rl.c file and related minor
modifications.  I find it's the most visually appealing of the kbd fonts which
is why I use it and selected it for conversion.  I believe the font is GPL'd.

Subject: [PATCH 425/571] [PATCH] fbdev: Add helper to get an appropriate
 initial mode

Add new helper, fb_find_best_display(), which will search the modelist for the
best mode for the attached display.  This requires an EDID block that is
converted to struct fb_monspecs and a private modelist.  The search will be
done in this manner:

- if 1st detailed timing is preferred, use that
- else if dimensions of the display are known, use that to estimate xres and
- else if modelist has detailed timings, use the first detailed timing
- else, use the very first entry from the modelist

Subject: [PATCH 429/571] [PATCH] matroxfb: Add support for Mystique AGP
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add new entries for Mystique AGP with the PCI ID 0x051e.

I don't actually have such boards but according to google they do exist.
Curiosly X.Org doesn't recognize that PCI ID.  And what's even more
interesting is that Matrox's own Windows drivers don't recognize it either.
After going through about a dozen different versions I did find one older
driver that does list this particular ID.  It is also listed in the pci.ids
file.

I'm not sure if non-220 AGP chips exist.  I left the chip revision check
intact for AGP chips nonetheless.

Use the CACHEFLUSH register on all chip types.  The register is listed in all
other specs except 2064W.  However I have verified that the register does work
on a 2064W despite being marked reserved in the specs.  There were no
noticeable side effects after writing to the register.

Content-Transfer-Encoding: 8bit

The current init code sets hiprilvl to 0 and maxhipri to 5.  According to the
specs those values are illegal on both G200 and G400.  It also causes
distortions on the TV-out at least when CRTC2 is in YUV mode as is the case
with DirectFB.  This patch resets both values to 0.

Subject: [PATCH 437/571] [PATCH] jbd doc: fix some kernel-doc warnings

Add structure fields kernel-doc for 2 fields in struct journal_s.

Warning(/var/linsrc/linux-2614-rc4//include/linux/jbd.h:808): No description found for parameter 'j_wbuf'
Warning(/var/linsrc/linux-2614-rc4//include/linux/jbd.h:808): No description found for parameter 'j_wbufsize'

Convert fs/jbd/recovery.c non-static functions to kernel-doc format.

fs/jbd/recovery.c doesn't export any symbols, so it should use
!I instead of !E to eliminate this warning message:

Convert to proper kernel-doc format.

Some have extra blank lines (not allowed immed.  after the function name)
or need blank lines (after all parameters).  Function summary must be only
one line.

Colon (":") in a function description does weird things (causes kernel-doc
to think that it's a new section head sadly).

+The Virtual File System (also known as the Virtual Filesystem Switch)
+is the software layer in the kernel that provides the filesystem
+interface to userspace programs. It also provides an abstraction
+within the kernel which allows different filesystem implementations to
+coexist.
+
+VFS system calls open(2), stat(2), read(2), write(2), chmod(2) and so
+on are called from a process context. Filesystem locking is described
+in the document Documentation/filesystems/Locking.
 
 
-A Quick Look At How It Works
-============================
+Directory Entry Cache (dcache)
+------------------------------
 
-In this section I'll briefly describe how things work, before
-launching into the details. I'll start with describing what happens

+RCU-based dcache locking model
+==============================
+
+On many workloads, the most common operation on dcache is to look up a
+dentry, given a parent dentry and the name of the child. Typically,
+for every open(), stat() etc., the dentry corresponding to the
+pathname will be looked up by walking the tree starting with the first
+component of the pathname and using that dentry along with the next
+component to look up the next level and so on. Since it is a frequent
+operation for workloads like multiuser environments and web servers,
+it is important to optimize this path.
+
+Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus in
+every component during path look-up. Since 2.5.10 onwards, fast-walk
+algorithm changed this by holding the dcache_lock at the beginning and
+walking as many cached path component dentries as possible. This
+significantly decreases the number of acquisition of
+dcache_lock. However it also increases the lock hold time
+significantly and affects performance in large SMP machines. Since
+2.5.62 kernel, dcache has been using a new locking model that uses RCU
+to make dcache look-up lock-free.
+
+The current dcache locking model is not very different from the
+existing dcache locking model. Prior to 2.5.62 kernel, dcache_lock
+protected the hash chain, d_child, d_alias, d_lru lists as well as
+d_inode and several other things like mount look-up. RCU-based changes
+affect only the way the hash chain is protected. For everything else
+the dcache_lock must be taken for both traversing as well as
+updating. The hash chain updates too take the dcache_lock.  The
+significant change is the way d_lookup traverses the hash chain, it
+doesn't acquire the dcache_lock for this and rely on RCU to ensure
+that the dentry has not been *freed*.
+
+
+Dcache locking details
+======================
+
+For many multi-user workloads, open() and stat() on files are very
+frequently occurring operations. Both involve walking of path names to
+find the dentry corresponding to the concerned file. In 2.4 kernel,
+dcache_lock was held during look-up of each path component. Contention
+and cache-line bouncing of this global lock caused significant
+scalability problems. With the introduction of RCU in Linux kernel,
+this was worked around by making the look-up of path components during
+path walking lock-free.
+
+
+Safe lock-free look-up of dcache hash table
+===========================================
+
+Dcache is a complex data structure with the hash table entries also
+linked together in other lists. In 2.4 kernel, dcache_lock protected
+all the lists. We applied RCU only on hash chain walking. The rest of
+the lists are still protected by dcache_lock.  Some of the important
+changes are :
+
+1. The deletion from hash chain is done using hlist_del_rcu() macro
+   which doesn't initialize next pointer of the deleted dentry and
+   this allows us to walk safely lock-free while a deletion is
+   happening.
+
+2. Insertion of a dentry into the hash table is done using
+   hlist_add_head_rcu() which take care of ordering the writes - the
+   writes to the dentry must be visible before the dentry is
+   inserted. This works in conjunction with hlist_for_each_rcu() while
+   walking the hash chain. The only requirement is that all
+   initialization to the dentry must be done before
+   hlist_add_head_rcu() since we don't have dcache_lock protection
+   while traversing the hash chain. This isn't different from the
+   existing code.
+
+3. The dentry looked up without holding dcache_lock by cannot be
+   returned for walking if it is unhashed. It then may have a NULL
+   d_inode or other bogosity since RCU doesn't protect the other
+   fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
+   indicate unhashed dentries and use this in conjunction with a
+   per-dentry lock (d_lock). Once looked up without the dcache_lock,
+   we acquire the per-dentry lock (d_lock) and check if the dentry is
+   unhashed. If so, the look-up is failed. If not, the reference count
+   of the dentry is increased and the dentry is returned.
+
+4. Once a dentry is looked up, it must be ensured during the path walk
+   for that component it doesn't go away. In pre-2.5.10 code, this was
+   done holding a reference to the dentry. dcache_rcu does the same.
+   In some sense, dcache_rcu path walking looks like the pre-2.5.10
+   version.
+
+5. All dentry hash chain updates must take the dcache_lock as well as
+   the per-dentry lock in that order. dput() does this to ensure that
+   a dentry that has just been looked up in another CPU doesn't get
+   deleted before dget() can be done on it.
+
+6. There are several ways to do reference counting of RCU protected
+   objects. One such example is in ipv4 route cache where deferred
+   freeing (using call_rcu()) is done as soon as the reference count
+   goes to zero. This cannot be done in the case of dentries because
+   tearing down of dentries require blocking (dentry_iput()) which
+   isn't supported from RCU callbacks. Instead, tearing down of
+   dentries happen synchronously in dput(), but actual freeing happens
+   later when RCU grace period is over. This allows safe lock-free
+   walking of the hash chains, but a matched dentry may have been
+   partially torn down. The checking of DCACHE_UNHASHED flag with
+   d_lock held detects such dentries and prevents them from being
+   returned from look-up.
+
+
+Maintaining POSIX rename semantics
+==================================
+
+Since look-up of dentries is lock-free, it can race against a
+concurrent rename operation. For example, during rename of file A to
+B, look-up of either A or B must succeed.  So, if look-up of B happens
+after A has been removed from the hash chain but not added to the new
+hash chain, it may fail.  Also, a comparison while the name is being
+written concurrently by a rename may result in false positive matches
+violating rename semantics.  Issues related to race with rename are
+handled as described below :
+
+1. Look-up can be done in two ways - d_lookup() which is safe from
+   simultaneous renames and __d_lookup() which is not.  If
+   __d_lookup() fails, it must be followed up by a d_lookup() to
+   correctly determine whether a dentry is in the hash table or
+   not. d_lookup() protects look-ups using a sequence lock
+   (rename_lock).
+
+2. The name associated with a dentry (d_name) may be changed if a
+   rename is allowed to happen simultaneously. To avoid memcmp() in
+   __d_lookup() go out of bounds due to a rename and false positive
+   comparison, the name comparison is done while holding the
+   per-dentry lock. This prevents concurrent renames during this
+   operation.
+
+3. Hash table walking during look-up may move to a different bucket as
+   the current dentry is moved to a different bucket due to rename.
+   But we use hlists in dcache hash table and they are
+   null-terminated.  So, even if a dentry moves to a different bucket,
+   hash chain walk will terminate. [with a list_head list, it may not
+   since termination is when the list_head in the original bucket is
+   reached].  Since we redo the d_parent check and compare name while
+   holding d_lock, lock-free look-up will not race against d_move().
+
+4. There can be a theoretical race when a dentry keeps coming back to
+   original bucket due to double moves. Due to this look-up may
+   consider that it has never moved and can end up in a infinite loop.
+   But this is not any worse that theoretical livelocks we already
+   have in the kernel.
+
+
+Important guidelines for filesystem developers related to dcache_rcu
+====================================================================
+
+1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
+   don't change. Only dcache internal implementation changes. However
+   filesystems *must not* delete from the dentry hash chains directly
+   using the list macros like allowed earlier. They must use dcache
+   APIs like d_drop() or __d_drop() depending on the situation.
+
+2. d_flags is now protected by a per-dentry lock (d_lock). All access
+   to d_flags must be protected by it.
+
+3. For a hashed dentry, checking of d_count needs to be protected by
+   d_lock.

-   hlist_add_head_rcu() which take care of ordering the writes -
-   the writes to the dentry must be visible before the dentry
-   is inserted. This works in conjunction with hlist_for_each_rcu()
-   while walking the hash chain. The only requirement is that
-   all initialization to the dentry must be done before hlist_add_head_rcu()
-   since we don't have dcache_lock protection while traversing
-   the hash chain. This isn't different from the existing code.
-
-3. The dentry looked up without holding dcache_lock by cannot be
-   returned for walking if it is unhashed. It then may have a NULL
-   d_inode or other bogosity since RCU doesn't protect the other
-   fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
-   indicate unhashed  dentries and use this in conjunction with a
-   per-dentry lock (d_lock). Once looked up without the dcache_lock,
-   we acquire the per-dentry lock (d_lock) and check if the
-   dentry is unhashed. If so, the look-up is failed. If not, the
-   reference count of the dentry is increased and the dentry is returned.
-
-4. Once a dentry is looked up, it must be ensured during the path
-   walk for that component it doesn't go away. In pre-2.5.10 code,
-   this was done holding a reference to the dentry. dcache_rcu does
-   the same.  In some sense, dcache_rcu path walking looks like
-   the pre-2.5.10 version.
-
-5. All dentry hash chain updates must take the dcache_lock as well as
-   the per-dentry lock in that order. dput() does this to ensure
-   that a dentry that has just been looked up in another CPU
-   doesn't get deleted before dget() can be done on it.
-
-6. There are several ways to do reference counting of RCU protected
-   objects. One such example is in ipv4 route cache where
-   deferred freeing (using call_rcu()) is done as soon as
-   the reference count goes to zero. This cannot be done in
-   the case of dentries because tearing down of dentries
-   require blocking (dentry_iput()) which isn't supported from
-   RCU callbacks. Instead, tearing down of dentries happen
-   synchronously in dput(), but actual freeing happens later
-   when RCU grace period is over. This allows safe lock-free
-   walking of the hash chains, but a matched dentry may have
-   been partially torn down. The checking of DCACHE_UNHASHED
-   flag with d_lock held detects such dentries and prevents
-   them from being returned from look-up.
-
-
-Maintaining POSIX rename semantics
-==================================
-
-Since look-up of dentries is lock-free, it can race against
-a concurrent rename operation. For example, during rename
-of file A to B, look-up of either A or B must succeed.
-So, if look-up of B happens after A has been removed from the
-hash chain but not added to the new hash chain, it may fail.
-Also, a comparison while the name is being written concurrently
-by a rename may result in false positive matches violating
-rename semantics.  Issues related to race with rename are
-handled as described below :
-
-1. Look-up can be done in two ways - d_lookup() which is safe
-   from simultaneous renames and __d_lookup() which is not.
-   If __d_lookup() fails, it must be followed up by a d_lookup()
-   to correctly determine whether a dentry is in the hash table
-   or not. d_lookup() protects look-ups using a sequence
-   lock (rename_lock).
-
-2. The name associated with a dentry (d_name) may be changed if
-   a rename is allowed to happen simultaneously. To avoid memcmp()
-   in __d_lookup() go out of bounds due to a rename and false
-   positive comparison, the name comparison is done while holding the
-   per-dentry lock. This prevents concurrent renames during this
-   operation.
-
-3. Hash table walking during look-up may move to a different bucket as
-   the current dentry is moved to a different bucket due to rename.
-   But we use hlists in dcache hash table and they are null-terminated.
-   So, even if a dentry moves to a different bucket, hash chain
-   walk will terminate. [with a list_head list, it may not since
-   termination is when the list_head in the original bucket is reached].
-   Since we redo the d_parent check and compare name while holding
-   d_lock, lock-free look-up will not race against d_move().
-
-4. There can be a theoretical race when a dentry keeps coming back
-   to original bucket due to double moves. Due to this look-up may
-   consider that it has never moved and can end up in a infinite loop.
-   But this is not any worse that theoretical livelocks we already
-   have in the kernel.
-
-
-Important guidelines for filesystem developers related to dcache_rcu
-====================================================================
-
-1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
-   don't change. Only dcache internal implementation changes. However
-   filesystems *must not* delete from the dentry hash chains directly
-   using the list macros like allowed earlier. They must use dcache
-   APIs like d_drop() or __d_drop() depending on the situation.
-
-2. d_flags is now protected by a per-dentry lock (d_lock). All
-   access to d_flags must be protected by it.
-
-3. For a hashed dentry, checking of d_count needs to be protected
-   by d_lock.
-
-
-Papers and other documentation on dcache locking
-================================================
-
-1. Scaling dcache with RCU (http://linuxjournal.com/article.php?sid=7124).
-
-2. http://lse.sourceforge.net/locking/dcache/dcache.html

+ramfs, rootfs and initramfs
+October 17, 2005
+Rob Landley <rob@landley.net>
+=============================
+
+What is ramfs?
+--------------
+
+Ramfs is a very simple filesystem that exports Linux's disk caching
+mechanisms (the page cache and dentry cache) as a dynamically resizable
+ram-based filesystem.
+
+Normally all files are cached in memory by Linux.  Pages of data read from
+backing store (usually the block device the filesystem is mounted on) are kept
+around in case it's needed again, but marked as clean (freeable) in case the
+Virtual Memory system needs the memory for something else.  Similarly, data
+written to files is marked clean as soon as it has been written to backing
+store, but kept around for caching purposes until the VM reallocates the
+memory.  A similar mechanism (the dentry cache) greatly speeds up access to
+directories.
+
+With ramfs, there is no backing store.  Files written into ramfs allocate
+dentries and page cache as usual, but there's nowhere to write them to.
+This means the pages are never marked clean, so they can't be freed by the
+VM when it's looking to recycle memory.
+
+The amount of code required to implement ramfs is tiny, because all the
+work is done by the existing Linux caching infrastructure.  Basically,
+you're mounting the disk cache as a filesystem.  Because of this, ramfs is not
+an optional component removable via menuconfig, since there would be negligible
+space savings.
+
+ramfs and ramdisk:
+------------------
+
+The older "ram disk" mechanism created a synthetic block device out of
+an area of ram and used it as backing store for a filesystem.  This block
+device was of fixed size, so the filesystem mounted on it was of fixed
+size.  Using a ram disk also required unnecessarily copying memory from the
+fake block device into the page cache (and copying changes back out), as well
+as creating and destroying dentries.  Plus it needed a filesystem driver
+(such as ext2) to format and interpret this data.
+
+Compared to ramfs, this wastes memory (and memory bus bandwidth), creates
+unnecessary work for the CPU, and pollutes the CPU caches.  (There are tricks
+to avoid this copying by playing with the page tables, but they're unpleasantly
+complicated and turn out to be about as expensive as the copying anyway.)
+More to the point, all the work ramfs is doing has to happen _anyway_,
+since all file access goes through the page and dentry caches.  The ram
+disk is simply unnecessary, ramfs is internally much simpler.
+
+Another reason ramdisks are semi-obsolete is that the introduction of
+loopback devices offered a more flexible and convenient way to create
+synthetic block devices, now from files instead of from chunks of memory.
+See losetup (8) for details.
+
+ramfs and tmpfs:
+----------------
+
+One downside of ramfs is you can keep writing data into it until you fill
+up all memory, and the VM can't free it because the VM thinks that files
+should get written to backing store (rather than swap space), but ramfs hasn't
+got any backing store.  Because of this, only root (or a trusted user) should
+be allowed write access to a ramfs mount.
+
+A ramfs derivative called tmpfs was created to add size limits, and the ability
+to write the data to swap space.  Normal users can be allowed write access to
+tmpfs mounts.  See Documentation/filesystems/tmpfs.txt for more information.
+
+What is rootfs?
+---------------
+
+Rootfs is a special instance of ramfs, which is always present in 2.6 systems.
+(It's used internally as the starting and stopping point for searches of the
+kernel's doubly-linked list of mount points.)
+
+Most systems just mount another filesystem over it and ignore it.  The
+amount of space an empty instance of ramfs takes up is tiny.
+
+What is initramfs?
+------------------
+
+All 2.6 Linux kernels contain a gzipped "cpio" format archive, which is
+extracted into rootfs when the kernel boots up.  After extracting, the kernel
+checks to see if rootfs contains a file "init", and if so it executes it as PID
+1.  If found, this init process is responsible for bringing the system the
+rest of the way up, including locating and mounting the real root device (if
+any).  If rootfs does not contain an init program after the embedded cpio
+archive is extracted into it, the kernel will fall through to the older code
+to locate and mount a root partition, then exec some variant of /sbin/init
+out of that.
+
+All this differs from the old initrd in several ways:
+
+  - The old initrd was a separate file, while the initramfs archive is linked
+    into the linux kernel image.  (The directory linux-*/usr is devoted to
+    generating this archive during the build.)
+
+  - The old initrd file was a gzipped filesystem image (in some file format,
+    such as ext2, that had to be built into the kernel), while the new
+    initramfs archive is a gzipped cpio archive (like tar only simpler,
+    see cpio(1) and Documentation/early-userspace/buffer-format.txt).
+
+  - The program run by the old initrd (which was called /initrd, not /init) did
+    some setup and then returned to the kernel, while the init program from
+    initramfs is not expected to return to the kernel.  (If /init needs to hand
+    off control it can overmount / with a new root device and exec another init
+    program.  See the switch_root utility, below.)
+
+  - When switching another root device, initrd would pivot_root and then
+    umount the ramdisk.  But initramfs is rootfs: you can neither pivot_root
+    rootfs, nor unmount it.  Instead delete everything out of rootfs to
+    free up the space (find -xdev / -exec rm '{}' ';'), overmount rootfs
+    with the new root (cd /newmount; mount --move . /; chroot .), attach
+    stdin/stdout/stderr to the new /dev/console, and exec the new init.
+
+    Since this is a remarkably persnickity process (and involves deleting
+    commands before you can run them), the klibc package introduced a helper
+    program (utils/run_init.c) to do all this for you.  Most other packages
+    (such as busybox) have named this command "switch_root".
+
+Populating initramfs:
+---------------------
+
+The 2.6 kernel build process always creates a gzipped cpio format initramfs
+archive and links it into the resulting kernel binary.  By default, this
+archive is empty (consuming 134 bytes on x86).  The config option
+CONFIG_INITRAMFS_SOURCE (for some reason buried under devices->block devices
+in menuconfig, and living in usr/Kconfig) can be used to specify a source for
+the initramfs archive, which will automatically be incorporated into the
+resulting binary.  This option can point to an existing gzipped cpio archive, a
+directory containing files to be archived, or a text file specification such
+as the following example:
+
+  dir /dev 755 0 0
+  nod /dev/console 644 0 0 c 5 1
+  nod /dev/loop0 644 0 0 b 7 0
+  dir /bin 755 1000 1000
+  slink /bin/sh busybox 777 0 0
+  file /bin/busybox initramfs/busybox 755 0 0
+  dir /proc 755 0 0
+  dir /sys 755 0 0
+  dir /mnt 755 0 0
+  file /init initramfs/init.sh 755 0 0
+
+One advantage of the text file is that root access is not required to
+set permissions or create device nodes in the new archive.  (Note that those
+two example "file" entries expect to find files named "init.sh" and "busybox" in
+a directory called "initramfs", under the linux-2.6.* directory.  See
+Documentation/early-userspace/README for more details.)
+
+If you don't already understand what shared libraries, devices, and paths
+you need to get a minimal root filesystem up and running, here are some
+references:
+http://www.tldp.org/HOWTO/Bootdisk-HOWTO/
+http://www.tldp.org/HOWTO/From-PowerUp-To-Bash-Prompt-HOWTO.html
+http://www.linuxfromscratch.org/lfs/view/stable/
+
+The "klibc" package (http://www.kernel.org/pub/linux/libs/klibc) is
+designed to be a tiny C library to statically link early userspace
+code against, along with some related utilities.  It is BSD licensed.
+
+I use uClibc (http://www.uclibc.org) and busybox (http://www.busybox.net)
+myself.  These are LGPL and GPL, respectively.
+
+In theory you could use glibc, but that's not well suited for small embedded
+uses like this.  (A "hello world" program statically linked against glibc is
+over 400k.  With uClibc it's 7k.  Also note that glibc dlopens libnss to do
+name lookups, even when otherwise statically linked.)
+
+Future directions:
+------------------
+
+Today (2.6.14), initramfs is always compiled in, but not always used.  The
+kernel falls back to legacy boot code that is reached only if initramfs does
+not contain an /init program.  The fallback is legacy code, there to ensure a
+smooth transition and allowing early boot functionality to gradually move to
+"early userspace" (I.E. initramfs).
+
+The move to early userspace is necessary because finding and mounting the real
+root device is complex.  Root partitions can span multiple devices (raid or
+separate journal).  They can be out on the network (requiring dhcp, setting a
+specific mac address, logging into a server, etc).  They can live on removable
+media, with dynamically allocated major/minor numbers and persistent naming
+issues requiring a full udev implementation to sort out.  They can be
+compressed, encrypted, copy-on-write, loopback mounted, strangely partitioned,
+and so on.
+
+This kind of complexity (which inevitably includes policy) is rightly handled
+in userspace.  Both klibc and busybox/uClibc are working on simple initramfs
+packages to drop into a kernel build, and when standard solutions are ready
+and widely deployed, the kernel's legacy early boot code will become obsolete
+and a candidate for the feature removal schedule.
+
+But that's a while off yet.

Use schedule_timeout_interruptible() instead of
set_current_state()/schedule_timeout() to reduce kernel size.  Also use
msecs_to_jiffies() instead of direct HZ division to avoid rounding errors.

Subject: [PATCH 491/571] [PATCH] drivers/pnp/: cleanups

This patch contains the following possible cleanups:
- make needlessly global code static
- #if 0 the following unused global function:
  - core.c: pnp_remove_device
- #if 0 the following unneeded EXPORT_SYMBOL's:
  - card.c: pnp_add_card
  - card.c: pnp_remove_card
  - card.c: pnp_add_card_device
  - card.c: pnp_remove_card_device
  - card.c: pnp_add_card_id
  - core.c: pnp_register_protocol
  - core.c: pnp_unregister_protocol
  - core.c: pnp_add_device
  - core.c: pnp_remove_device
  - pnpacpi/core.c: pnpacpi_protocol
  - driver.c: pnp_add_id
  - isapnp/core.c: isapnp_read_byte
  - manager.c: pnp_auto_config_dev
  - resource.c: pnp_register_dependent_option
  - resource.c: pnp_register_independent_option
  - resource.c: pnp_register_irq_resource
  - resource.c: pnp_register_dma_resource
  - resource.c: pnp_register_port_resource
  - resource.c: pnp_register_mem_resource

Note that this patch #if 0's exactly one functions and removes no
functions.  Most it does is the #if 0 of EXPORT_SYMBOL's, so if any modular
code will use any of them, re-adding will be trivial.

Modular ISAPnP might be interesting in some cases, but this is more legacy
code.  If someone would work on it to sort all the issues out (starting
with the point that most users of __ISAPNP__ will have to be fixed)
re-enabling the required EXPORT_SYMBOL's won't be hard for him.

Subject: [PATCH 499/571] [PATCH] m68knommu: modify the ColdFire PIT timer for
 new 5208

Modified common ColdFire PIT timer code to support the 5208 as well.
It uses a different set of mask and interrupt bits than other ColdFire
processors. The defines for these bits have been moved in header
files and set appropriately for the different processor varients.
Patch originally from Matt Waddel.

Subject: [PATCH 500/571] [PATCH] m68knommu: handle non base address 0 memory
 of M5208EVB board

The Freescale M5208EVB ColdFire eval board is one of the few that
doesn't have its DRAM based at address 0. Handle this special case
in the common ColdFire startup code.

Patch originally from Matt Waddel.

Subject: [PATCH 501/571] [PATCH] m68knommu: align param section and add
 5208EVB linker support

Align the param section. It can end up starting on an unalingned
boundary depending on the size of ksymtab_strings. If it is
unaligned things like modules will fail to load with unaligned
access traps.

Add linker scipt support for the M5208EVB board.

Subject: [PATCH 507/571] [PATCH] m68knommu: move some platform irq support out
 of irq.h

Move some of the m68knommu platform specific irq core support
to its own header, irqnode.h. Having it in asm-m68knommu/irq.h
causes some build pain, since it is included in a number of
common code places (and not all the required definitions will
be included at these places).

Subject: [PATCH 516/571] Remove mips_rtc_lock

The mips_rtc_lock is no longer needed because RTC operations should be
protected already by other mechanism. (rtc_lock, local_irq_save, etc.)

Also, locking whole rtc_get_time/rtc_set_time should be avoided while
some RTC routines might take very long time (a few seconds).

Subject: [PATCH 517/571] Use rtc_lock to protect RTC operations

Many RTC routines were not protected against each other, so there are
potential races, for example, ntp-update against /dev/rtc.  This patch
fixes them using rtc_lock.

Subject: [PATCH 526/571] [ARM] 3117/1: nwfpe kernel memory info leak

Patch from Lennert Buytenhek

The routine that nwfpe uses for converting floats/doubles to
extended precision fails to zero two bytes of kernel stack.  This
is not immediately obvious, as the floatx80 structure has 16 bits
of implicit padding (by design.)  These two bytes are copied to
userspace when an stfe is emulated, causing a possible info leak.

Make the padding explicit and zero it out in the relevant places.

Subject: [PATCH 527/571] [ARM] 3118/1: fix and reenable nwfpe extended
 precision emulation for big-endian

Patch from Lennert Buytenhek

nwfpe extended precision emulation used to be broken on big-endian
and was therefore disabled.  This patch fixes nwfpe so that it copies
extended precision floats to/from userspace in the proper word order
(similar to patch #2046, see the description of that patch for an
explanation) and reenables the Kconfig option.

Subject: [PATCH 528/571] [ARM] 3121/1: unconditionally use XCB=101 on ixp2000

Patch from Lennert Buytenhek

Since we have to use XCB=101 instead of XCB=000 on the ixp2400 to
prevent it from regularly falling over, and since we have to deal with
manual write buffer flushing because of that, we might as well use
XCB=101 on all ixp2000 platforms since it's faster than XCB=000.

Subject: [PATCH 532/571] [SPARC]: Make SBUS dma code similar to EBUS

From: Georg Chini <georg.chini@triaton-webhosting.com>

Introduce some sbus_dma routines similar to the
ebus_dma stuff to make the code look nearly the same
for both cases.

Thanks to Christopher for testing.

Subject: [PATCH 533/571] [SPARC64] mm: don't re-evaluate *ptep

sparc64 prom_callback and new_setup_frame32 each operates on a user page
table without holding lock, and no doubt they've good reason.  But I'd
feel more confident if they were to do a "pte = *ptep" and then operate
on pte, rather than re-evaluating *ptep.

Subject: [PATCH 534/571] [SPARC64] mm: context switch ptlock

sparc64 is unique among architectures in taking the page_table_lock in
its context switch (well, cris does too, but erroneously, and it's not
yet SMP anyway).

This seems to be a private affair between switch_mm and activate_mm,
using page_table_lock as a per-mm lock, without any relation to its uses
elsewhere.  That's fine, but comment it as such; and unlock sooner in
switch_mm, more like in activate_mm (preemption is disabled here).

There is a block of "if (0)"ed code in smp_flush_tlb_pending which would
have liked to rely on the page_table_lock, in switch_mm and elsewhere;
but its comment explains how dup_mmap's flush_tlb_mm defeated it.  And
though that could have been changed at any time over the past few years,
now the chance vanishes as we push the page_table_lock downwards, and
perhaps split it per page table page.  Just delete that block of code.

Which leaves the mysterious spin_unlock_wait(&oldmm->page_table_lock)
in kernel/fork.c copy_mm.  Textual analysis (supported by Nick Piggin)
suggests that the comment was written by DaveM, and that it relates to
the defeated approach in the sparc64 smp_flush_tlb_pending.  Just delete
this block too.

Subject: [PATCH 537/571] [SPARC64] mm: Do not flush TLB mm in tlb_finish_mmu()

It isn't needed any longer, as noted by Hugh Dickins.

We still need the flush routines, due to the one remaining
call site in hugetlb_prefault_arch_hook().  That can be
eliminated at some later point, however.

From: Christoph Hellwig <hch@lst.de>
Date: Mon, 7 Nov 2005 14:11:25 -0800
Subject: [PATCH 543/571] [SPARC]: remove kbio.h

The old keyboard driver is gone in 2.6, so the only user left are the
compat ioctls.

Minor simplification to the sparc64 tlb_flush_mmu: tlb_remove_page
set need_flush only after handling the tlb_fast_mode case, then
tlb_flush_mmu need not consider whether it's tlb_fast_mode.

Subject: [PATCH 554/571] [PATCH] saner handling of auto_acct_off() and
 DQUOT_OFF() in umount

The way we currently deal with quota and process accounting that might
keep vfsmount busy at umount time is inherently broken; we try to turn
them off just in case (not quite correctly, at that) and

  a) pray umount doesn't fail (otherwise they'll stay turned off)
  b) pray nobody doesn anything funny just as we turn quota off

Moreover, LSM provides hooks for doing the same sort of broken logics.

The proper way to deal with that is to introduce the second kind of
reference to vfsmount.  Semantics:

 - when the last normal reference is dropped, all special ones are
   converted to normal ones and if there had been any, cleanup is done.
 - normal reference can be cloned into a special one
 - special reference can be converted to normal one; that's a no-op if
   we'd already passed the point of no return (i.e.  mntput() had
   converted special references to normal and started cleanup).

The way it works: e.g. starting process accounting converts the vfsmount
reference pinned by the opened file into special one and turns it back
to normal when it gets shut down; acct_auto_close() is done when no
normal references are left.  That way it does *not* obstruct umount(2)
and it silently gets turned off when the last normal reference to
vfsmount is gone.  Which is exactly what we want...

The same should be done by LSM module that holds some internal
references to vfsmount and wants to shut them down on umount - it should
make them special and security_sb_umount_close() will be called exactly
when the last normal reference to vfsmount is gone.

quota handling is even simpler - we don't use normal file IO anymore, so
there's no need to hold vfsmounts at all.  DQUOT_OFF() is done from
deactivate_super(), where it really belongs.

 - check_mnt() on the source of binding should've been unconditional
   from the very beginning.  My fault - as far I could've trace it,
   that's an old thinko made back in 2001.  Kudos to Miklos for spotting
   it...

   Fixed.

 - code cleaned up.

Subject: [PATCH 556/571] [PATCH] allow callers of seq_open do allocation
 themselves

Allow caller of seq_open() to kmalloc() seq_file + whatever else they
want and set ->private_data to it.  seq_open() will then abstain from
doing allocation itself.

Subject: [PATCH 559/571] [PATCH] sanitize the interface of graft_tree().

Old semantics: graft_tree() grabs a reference on the vfsmount before
returning success.

New one: graft_tree() leaves that to caller.

All the callers of graft_tree() immediately dropped that reference
anyway.  Changing the interface takes care of this unnecessary overhead.

Idea proposed by Al Viro.

Subject: [PATCH 560/571] [PATCH] umount_tree() locking change

umount is done under the protection of the namespace semaphore.  This
can lead to intresting deadlocks when the last reference to a mount is
released, if filesystem code is in sufficiently nasty state.

This collects all the to-be-released-mounts and releases them after
releasing the namespace semaphore.  That both reduces the time we are
holding namespace semaphore and gets the things more robust.

Idea proposed by Al Viro.

Subject: [PATCH 564/571] [PATCH] introduce shared mounts

This creates shared mounts.  A shared mount when bind-mounted to some
mountpoint, propagates mount/umount events to each other.  All the
shared mounts that propagate events to each other belong to the same
peer-group.

Subject: [PATCH 567/571] [PATCH] shared mounts handling: umount

An unmount of a mount creates a umount event on the parent.  If the
parent is a shared mount, it gets propagated to all mounts in the peer
group.

Subject: [PATCH 568/571] [PATCH] introduce slave mounts

A slave mount always has a master mount from which it receives
mount/umount events.  Unlike shared mount the event propagation does not
flow from the slave mount to the master.

Subject: [PATCH 570/571] [PATCH] unbindable mounts

An unbindable mount does not forward or receive propagation.  Also
unbindable mount disallows bind mounts.  The semantics is as follows.

Bind semantics:
  It is invalid to bind mount an unbindable mount.

Move semantics:
  It is invalid to move an unbindable mount under shared mount.

Clone-namespace semantics:
  If a mount is unbindable in the parent namespace, the corresponding
  cloned mount in the child namespace becomes unbindable too.  Note:
  there is subtle difference, unbindable mounts cannot be bind mounted
  but can be cloned during clone-namespace.

+Shared Subtrees
+---------------
+
+Contents:
+	1) Overview
+	2) Features
+	3) smount command
+	4) Use-case
+	5) Detailed semantics
+	6) Quiz
+	7) FAQ
+	8) Implementation
+
+
+1) Overview
+-----------
+
+Consider the following situation:
+
+A process wants to clone its own namespace, but still wants to access the CD
+that got mounted recently.  Shared subtree semantics provide the necessary
+mechanism to accomplish the above.
+
+It provides the necessary building blocks for features like per-user-namespace
+and versioned filesystem.
+
+2) Features
+-----------
+
+Shared subtree provides four different flavors of mounts; struct vfsmount to be
+precise
+
+	a. shared mount
+	b. slave mount
+	c. private mount
+	d. unbindable mount
+
+
+2a) A shared mount can be replicated to as many mountpoints and all the
+replicas continue to be exactly same.
+
+	Here is an example:
+
+	Lets say /mnt has a mount that is shared.
+	mount --make-shared /mnt
+
+	note: mount command does not yet support the --make-shared flag.
+	I have included a small C program which does the same by executing
+	'smount /mnt shared'
+
+	#mount --bind /mnt /tmp
+	The above command replicates the mount at /mnt to the mountpoint /tmp
+	and the contents of both the mounts remain identical.
+
+	#ls /mnt
+	a b c
+
+	#ls /tmp
+	a b c
+
+	Now lets say we mount a device at /tmp/a
+	#mount /dev/sd0  /tmp/a
+
+	#ls /tmp/a
+	t1 t2 t2
+
+	#ls /mnt/a
+	t1 t2 t2
+
+	Note that the mount has propagated to the mount at /mnt as well.
+
+	And the same is true even when /dev/sd0 is mounted on /mnt/a. The
+	contents will be visible under /tmp/a too.
+
+
+2b) A slave mount is like a shared mount except that mount and umount events
+	only propagate towards it.
+
+	All slave mounts have a master mount which is a shared.
+
+	Here is an example:
+
+	Lets say /mnt has a mount which is shared.
+	#mount --make-shared /mnt
+
+	Lets bind mount /mnt to /tmp
+	#mount --bind /mnt /tmp
+
+	the new mount at /tmp becomes a shared mount and it is a replica of
+	the mount at /mnt.
+
+	Now lets make the mount at /tmp; a slave of /mnt
+	#mount --make-slave /tmp
+	[or smount /tmp slave]
+
+	lets mount /dev/sd0 on /mnt/a
+	#mount /dev/sd0 /mnt/a
+
+	#ls /mnt/a
+	t1 t2 t3
+
+	#ls /tmp/a
+	t1 t2 t3
+
+	Note the mount event has propagated to the mount at /tmp
+
+	However lets see what happens if we mount something on the mount at /tmp
+
+	#mount /dev/sd1 /tmp/b
+
+	#ls /tmp/b
+	s1 s2 s3
+
+	#ls /mnt/b
+
+	Note how the mount event has not propagated to the mount at
+	/mnt
+
+
+2c) A private mount does not forward or receive propagation.
+
+	This is the mount we are familiar with. Its the default type.
+
+
+2d) A unbindable mount is a unbindable private mount
+
+	lets say we have a mount at /mnt and we make is unbindable
+
+	#mount --make-unbindable /mnt
+	 [ smount /mnt  unbindable ]
+
+	 Lets try to bind mount this mount somewhere else.
+	 # mount --bind /mnt /tmp
+	 mount: wrong fs type, bad option, bad superblock on /mnt,
+	        or too many mounted file systems
+
+	Binding a unbindable mount is a invalid operation.
+
+
+3) smount command
+
+	Currently the mount command is not aware of shared subtree features.
+	Work is in progress to add the support in mount ( util-linux package ).
+	Till then use the following program.

+
+	Copy the above code snippet into smount.c
+	gcc -o smount smount.c
+
+
+	(i) To mark all the mounts under /mnt as shared execute the following
+	command:
+
+	 	smount /mnt rshared
+		the corresponding syntax planned for mount command is
+		mount --make-rshared /mnt
+
+	    just to mark a mount /mnt as shared, execute the following
+	    command:
+	 	smount /mnt shared
+		the corresponding syntax planned for mount command is
+		mount --make-shared /mnt
+
+	(ii) To mark all the shared mounts under /mnt as slave execute the
+	following
+
+	     command:
+		smount /mnt rslave
+		the corresponding syntax planned for mount command is
+		mount --make-rslave /mnt
+
+	    just to mark a mount /mnt as slave, execute the following
+	    command:
+	 	smount /mnt slave
+		the corresponding syntax planned for mount command is
+		mount --make-slave /mnt
+
+	(iii) To mark all the mounts under /mnt as private execute the
+	following command:
+
+		smount /mnt rprivate
+		the corresponding syntax planned for mount command is
+		mount --make-rprivate /mnt
+
+	    just to mark a mount /mnt as private, execute the following
+	    command:
+	 	smount /mnt private
+		the corresponding syntax planned for mount command is
+		mount --make-private /mnt
+
+	      NOTE: by default all the mounts are created as private. But if
+	      you want to change some shared/slave/unbindable  mount as
+	      private at a later point in time, this command can help.
+
+	(iv) To mark all the mounts under /mnt as unbindable execute the
+	following
+
+	     command:
+		smount /mnt runbindable
+		the corresponding syntax planned for mount command is
+		mount --make-runbindable /mnt
+
+	    just to mark a mount /mnt as unbindable, execute the following
+	    command:
+	 	smount /mnt unbindable
+		the corresponding syntax planned for mount command is
+		mount --make-unbindable /mnt
+
+
+4) Use cases
+------------
+
+	A) A process wants to clone its own namespace, but still wants to
+	   access the CD that got mounted recently.
+
+	   Solution:
+
+		The system administrator can make the mount at /cdrom shared
+		mount --bind /cdrom /cdrom
+		mount --make-shared /cdrom
+
+		Now any process that clones off a new namespace will have a
+		mount at /cdrom which is a replica of the same mount in the
+		parent namespace.
+
+		So when a CD is inserted and mounted at /cdrom that mount gets
+		propagated to the other mount at /cdrom in all the other clone
+		namespaces.
+
+	B) A process wants its mounts invisible to any other process, but
+	still be able to see the other system mounts.
+
+	   Solution:
+
+		To begin with, the administrator can mark the entire mount tree
+		as shareable.
+
+		mount --make-rshared /
+
+		A new process can clone off a new namespace. And mark some part
+		of its namespace as slave
+
+		mount --make-rslave /myprivatetree
+
+		Hence forth any mounts within the /myprivatetree done by the
+		process will not show up in any other namespace. However mounts
+		done in the parent namespace under /myprivatetree still shows
+		up in the process's namespace.
+
+
+	Apart from the above semantics this feature provides the
+	building blocks to solve the following problems:
+
+	C)  Per-user namespace
+
+		The above semantics allows a way to share mounts across
+		namespaces.  But namespaces are associated with processes. If
+		namespaces are made first class objects with user API to
+		associate/disassociate a namespace with userid, then each user
+		could have his/her own namespace and tailor it to his/her
+		requirements. Offcourse its needs support from PAM.
+
+	D)  Versioned files
+
+		If the entire mount tree is visible at multiple locations, then
+		a underlying versioning file system can return different
+		version of the file depending on the path used to access that
+		file.
+
+		An example is:
+
+		mount --make-shared /
+		mount --rbind / /view/v1
+		mount --rbind / /view/v2
+		mount --rbind / /view/v3
+		mount --rbind / /view/v4
+
+		and if /usr has a versioning filesystem mounted, than that
+		mount appears at /view/v1/usr, /view/v2/usr, /view/v3/usr and
+		/view/v4/usr too
+
+		A user can request v3 version of the file /usr/fs/namespace.c
+		by accessing /view/v3/usr/fs/namespace.c . The underlying
+		versioning filesystem can then decipher that v3 version of the
+		filesystem is being requested and return the corresponding
+		inode.
+
+5) Detailed semantics:
+-------------------
+	The section below explains the detailed semantics of
+	bind, rbind, move, mount, umount and clone-namespace operations.
+
+	Note: the word 'vfsmount' and the noun 'mount' have been used
+	to mean the same thing, throughout this document.
+
+5a) Mount states
+
+	A given mount can be in one of the following states
+	1) shared
+	2) slave
+	3) shared and slave
+	4) private
+	5) unbindable
+
+	A 'propagation event' is defined as event generated on a vfsmount
+	that leads to mount or unmount actions in other vfsmounts.
+
+	A 'peer group' is defined as a group of vfsmounts that propagate
+	events to each other.
+
+	(1) Shared mounts
+
+		A 'shared mount' is defined as a vfsmount that belongs to a
+		'peer group'.
+
+		For example:
+			mount --make-shared /mnt
+			mount --bin /mnt /tmp
+
+		The mount at /mnt and that at /tmp are both shared and belong
+		to the same peer group. Anything mounted or unmounted under
+		/mnt or /tmp reflect in all the other mounts of its peer
+		group.
+
+
+	(2) Slave mounts
+
+		A 'slave mount' is defined as a vfsmount that receives
+		propagation events and does not forward propagation events.
+
+		A slave mount as the name implies has a master mount from which
+		mount/unmount events are received. Events do not propagate from
+		the slave mount to the master.  Only a shared mount can be made
+		a slave by executing the following command
+
+			mount --make-slave mount
+
+		A shared mount that is made as a slave is no more shared unless
+		modified to become shared.
+
+	(3) Shared and Slave
+
+		A vfsmount can be both shared as well as slave.  This state
+		indicates that the mount is a slave of some vfsmount, and
+		has its own peer group too.  This vfsmount receives propagation
+		events from its master vfsmount, and also forwards propagation
+		events to its 'peer group' and to its slave vfsmounts.
+
+		Strictly speaking, the vfsmount is shared having its own
+		peer group, and this peer-group is a slave of some other
+		peer group.
+
+		Only a slave vfsmount can be made as 'shared and slave' by
+		either executing the following command
+			mount --make-shared mount
+		or by moving the slave vfsmount under a shared vfsmount.
+
+	(4) Private mount
+
+		A 'private mount' is defined as vfsmount that does not
+		receive or forward any propagation events.
+
+	(5) Unbindable mount
+
+		A 'unbindable mount' is defined as vfsmount that does not
+		receive or forward any propagation events and cannot
+		be bind mounted.
+
+
+   	State diagram:
+   	The state diagram below explains the state transition of a mount,
+	in response to various commands.

+	|unbindable   |shared	   |**unbindable  |    private   | unbindable  |
+	------------------------------------------------------------------------
+
+	* if the shared mount is the only mount in its peer group, making it
+	slave, makes it private automatically. Note that there is no master to
+	which it can be slaved to.
+
+	** slaving a non-shared mount has no effect on the mount.
+
+	Apart from the commands listed below, the 'move' operation also changes
+	the state of a mount depending on type of the destination mount. Its
+	explained in section 5d.
+
+5b) Bind semantics
+
+	Consider the following command
+
+	mount --bind A/a  B/b
+
+	where 'A' is the source mount, 'a' is the dentry in the mount 'A', 'B'
+	is the destination mount and 'b' is the dentry in the destination mount.
+
+	The outcome depends on the type of mount of 'A' and 'B'. The table
+	below contains quick reference.

+
+     	Details:
+
+	1. 'A' is a shared mount and 'B' is a shared mount. A new mount 'C'
+	which is clone of 'A', is created. Its root dentry is 'a' . 'C' is
+	mounted on mount 'B' at dentry 'b'. Also new mount 'C1', 'C2', 'C3' ...
+	are created and mounted at the dentry 'b' on all mounts where 'B'
+	propagates to. A new propagation tree containing 'C1',..,'Cn' is
+	created. This propagation tree is identical to the propagation tree of
+	'B'.  And finally the peer-group of 'C' is merged with the peer group
+	of 'A'.
+
+	2. 'A' is a private mount and 'B' is a shared mount. A new mount 'C'
+	which is clone of 'A', is created. Its root dentry is 'a'. 'C' is
+	mounted on mount 'B' at dentry 'b'. Also new mount 'C1', 'C2', 'C3' ...
+	are created and mounted at the dentry 'b' on all mounts where 'B'
+	propagates to. A new propagation tree is set containing all new mounts
+	'C', 'C1', .., 'Cn' with exactly the same configuration as the
+	propagation tree for 'B'.
+
+	3. 'A' is a slave mount of mount 'Z' and 'B' is a shared mount. A new
+	mount 'C' which is clone of 'A', is created. Its root dentry is 'a' .
+	'C' is mounted on mount 'B' at dentry 'b'. Also new mounts 'C1', 'C2',
+	'C3' ... are created and mounted at the dentry 'b' on all mounts where
+	'B' propagates to. A new propagation tree containing the new mounts
+	'C','C1',..  'Cn' is created. This propagation tree is identical to the
+	propagation tree for 'B'. And finally the mount 'C' and its peer group
+	is made the slave of mount 'Z'.  In other words, mount 'C' is in the
+	state 'slave and shared'.
+
+	4. 'A' is a unbindable mount and 'B' is a shared mount. This is a
+	invalid operation.
+
+	5. 'A' is a private mount and 'B' is a non-shared(private or slave or
+	unbindable) mount. A new mount 'C' which is clone of 'A', is created.
+	Its root dentry is 'a'. 'C' is mounted on mount 'B' at dentry 'b'.
+
+	6. 'A' is a shared mount and 'B' is a non-shared mount. A new mount 'C'
+	which is a clone of 'A' is created. Its root dentry is 'a'. 'C' is
+	mounted on mount 'B' at dentry 'b'.  'C' is made a member of the
+	peer-group of 'A'.
+
+	7. 'A' is a slave mount of mount 'Z' and 'B' is a non-shared mount. A
+	new mount 'C' which is a clone of 'A' is created. Its root dentry is
+	'a'.  'C' is mounted on mount 'B' at dentry 'b'. Also 'C' is set as a
+	slave mount of 'Z'. In other words 'A' and 'C' are both slave mounts of
+	'Z'.  All mount/unmount events on 'Z' propagates to 'A' and 'C'. But
+	mount/unmount on 'A' do not propagate anywhere else. Similarly
+	mount/unmount on 'C' do not propagate anywhere else.
+
+	8. 'A' is a unbindable mount and 'B' is a non-shared mount. This is a
+	invalid operation. A unbindable mount cannot be bind mounted.
+
+5c) Rbind semantics
+
+	rbind is same as bind. Bind replicates the specified mount.  Rbind
+	replicates all the mounts in the tree belonging to the specified mount.
+	Rbind mount is bind mount applied to all the mounts in the tree.
+
+	If the source tree that is rbind has some unbindable mounts,
+	then the subtree under the unbindable mount is pruned in the new
+	location.
+
+	eg: lets say we have the following mount tree.
+
+		A
+	      /   \
+	      B   C
+	     / \ / \
+	     D E F G
+
+	     Lets say all the mount except the mount C in the tree are
+	     of a type other than unbindable.
+
+	     If this tree is rbound to say Z
+
+	     We will have the following tree at the new location.
+
+		Z
+		|
+		A'
+	       /
+	      B'		Note how the tree under C is pruned
+	     / \ 		in the new location.
+	    D' E'
+
+
+
+5d) Move semantics
+
+	Consider the following command
+
+	mount --move A  B/b
+
+	where 'A' is the source mount, 'B' is the destination mount and 'b' is
+	the dentry in the destination mount.
+
+	The outcome depends on the type of the mount of 'A' and 'B'. The table
+	below is a quick reference.

+   |   |      |               |                |                |            |
+   |   v      |               |                |                |            |

+   |non-shared| shared        |      private   |    slave       | unbindable |
+   ***************************************************************************
+	NOTE: moving a mount residing under a shared mount is invalid.
+
+      Details follow:
+
+	1. 'A' is a shared mount and 'B' is a shared mount.  The mount 'A' is
+	mounted on mount 'B' at dentry 'b'.  Also new mounts 'A1', 'A2'...'An'
+	are created and mounted at dentry 'b' on all mounts that receive
+	propagation from mount 'B'. A new propagation tree is created in the
+	exact same configuration as that of 'B'. This new propagation tree
+	contains all the new mounts 'A1', 'A2'...  'An'.  And this new
+	propagation tree is appended to the already existing propagation tree
+	of 'A'.
+
+	2. 'A' is a private mount and 'B' is a shared mount. The mount 'A' is
+	mounted on mount 'B' at dentry 'b'. Also new mount 'A1', 'A2'... 'An'
+	are created and mounted at dentry 'b' on all mounts that receive
+	propagation from mount 'B'. The mount 'A' becomes a shared mount and a
+	propagation tree is created which is identical to that of
+	'B'. This new propagation tree contains all the new mounts 'A1',
+	'A2'...  'An'.
+
+	3. 'A' is a slave mount of mount 'Z' and 'B' is a shared mount.  The
+	mount 'A' is mounted on mount 'B' at dentry 'b'.  Also new mounts 'A1',
+	'A2'... 'An' are created and mounted at dentry 'b' on all mounts that
+	receive propagation from mount 'B'. A new propagation tree is created
+	in the exact same configuration as that of 'B'. This new propagation
+	tree contains all the new mounts 'A1', 'A2'...  'An'.  And this new
+	propagation tree is appended to the already existing propagation tree of
+	'A'.  Mount 'A' continues to be the slave mount of 'Z' but it also
+	becomes 'shared'.
+
+	4. 'A' is a unbindable mount and 'B' is a shared mount. The operation
+	is invalid. Because mounting anything on the shared mount 'B' can
+	create new mounts that get mounted on the mounts that receive
+	propagation from 'B'.  And since the mount 'A' is unbindable, cloning
+	it to mount at other mountpoints is not possible.
+
+	5. 'A' is a private mount and 'B' is a non-shared(private or slave or
+	unbindable) mount. The mount 'A' is mounted on mount 'B' at dentry 'b'.
+
+	6. 'A' is a shared mount and 'B' is a non-shared mount.  The mount 'A'
+	is mounted on mount 'B' at dentry 'b'.  Mount 'A' continues to be a
+	shared mount.
+
+	7. 'A' is a slave mount of mount 'Z' and 'B' is a non-shared mount.
+	The mount 'A' is mounted on mount 'B' at dentry 'b'.  Mount 'A'
+	continues to be a slave mount of mount 'Z'.
+
+	8. 'A' is a unbindable mount and 'B' is a non-shared mount. The mount
+	'A' is mounted on mount 'B' at dentry 'b'. Mount 'A' continues to be a
+	unbindable mount.
+
+5e) Mount semantics
+
+	Consider the following command
+
+	mount device  B/b
+
+	'B' is the destination mount and 'b' is the dentry in the destination
+	mount.
+
+	The above operation is the same as bind operation with the exception
+	that the source mount is always a private mount.
+
+
+5f) Unmount semantics
+
+	Consider the following command
+
+	umount A
+
+	where 'A' is a mount mounted on mount 'B' at dentry 'b'.
+
+	If mount 'B' is shared, then all most-recently-mounted mounts at dentry
+	'b' on mounts that receive propagation from mount 'B' and does not have
+	sub-mounts within them are unmounted.
+
+	Example: Lets say 'B1', 'B2', 'B3' are shared mounts that propagate to
+	each other.
+
+	lets say 'A1', 'A2', 'A3' are first mounted at dentry 'b' on mount
+	'B1', 'B2' and 'B3' respectively.
+
+	lets say 'C1', 'C2', 'C3' are next mounted at the same dentry 'b' on
+	mount 'B1', 'B2' and 'B3' respectively.
+
+	if 'C1' is unmounted, all the mounts that are most-recently-mounted on
+	'B1' and on the mounts that 'B1' propagates-to are unmounted.
+
+	'B1' propagates to 'B2' and 'B3'. And the most recently mounted mount
+	on 'B2' at dentry 'b' is 'C2', and that of mount 'B3' is 'C3'.
+
+	So all 'C1', 'C2' and 'C3' should be unmounted.
+
+	If any of 'C2' or 'C3' has some child mounts, then that mount is not
+	unmounted, but all other mounts are unmounted. However if 'C1' is told
+	to be unmounted and 'C1' has some sub-mounts, the umount operation is
+	failed entirely.
+
+5g) Clone Namespace
+
+	A cloned namespace contains all the mounts as that of the parent
+	namespace.
+
+	Lets say 'A' and 'B' are the corresponding mounts in the parent and the
+	child namespace.
+
+	If 'A' is shared, then 'B' is also shared and 'A' and 'B' propagate to
+	each other.
+
+	If 'A' is a slave mount of 'Z', then 'B' is also the slave mount of
+	'Z'.
+
+	If 'A' is a private mount, then 'B' is a private mount too.
+
+	If 'A' is unbindable mount, then 'B' is a unbindable mount too.
+
+
+6) Quiz
+
+	A. What is the result of the following command sequence?
+
+		mount --bind /mnt /mnt
+		mount --make-shared /mnt
+		mount --bind /mnt /tmp
+		mount --move /tmp /mnt/1
+
+		what should be the contents of /mnt /mnt/1 /mnt/1/1 should be?
+		Should they all be identical? or should /mnt and /mnt/1 be
+		identical only?
+
+
+	B. What is the result of the following command sequence?
+
+		mount --make-rshared /
+		mkdir -p /v/1
+		mount --rbind / /v/1
+
+		what should be the content of /v/1/v/1 be?
+
+
+	C. What is the result of the following command sequence?
+
+		mount --bind /mnt /mnt
+		mount --make-shared /mnt
+		mkdir -p /mnt/1/2/3 /mnt/1/test
+		mount --bind /mnt/1 /tmp
+		mount --make-slave /mnt
+		mount --make-shared /mnt
+		mount --bind /mnt/1/2 /tmp1
+		mount --make-slave /mnt
+
+		At this point we have the first mount at /tmp and
+		its root dentry is 1. Lets call this mount 'A'
+		And then we have a second mount at /tmp1 with root
+		dentry 2. Lets call this mount 'B'
+		Next we have a third mount at /mnt with root dentry
+		mnt. Lets call this mount 'C'
+
+		'B' is the slave of 'A' and 'C' is a slave of 'B'
+		A -> B -> C
+
+		at this point if we execute the following command
+
+		mount --bind /bin /tmp/test
+
+		The mount is attempted on 'A'
+
+		will the mount propagate to 'B' and 'C' ?
+
+		what would be the contents of
+		/mnt/1/test be?
+
+7) FAQ
+
+	Q1. Why is bind mount needed? How is it different from symbolic links?
+		symbolic links can get stale if the destination mount gets
+		unmounted or moved. Bind mounts continue to exist even if the
+		other mount is unmounted or moved.
+
+	Q2. Why can't the shared subtree be implemented using exportfs?
+
+		exportfs is a heavyweight way of accomplishing part of what
+		shared subtree can do. I cannot imagine a way to implement the
+		semantics of slave mount using exportfs?
+
+	Q3 Why is unbindable mount needed?
+
+		Lets say we want to replicate the mount tree at multiple
+		locations within the same subtree.
+
+		if one rbind mounts a tree within the same subtree 'n' times
+		the number of mounts created is an exponential function of 'n'.
+		Having unbindable mount can help prune the unneeded bind
+		mounts. Here is a example.
+
+		step 1:
+		   lets say the root tree has just two directories with
+		   one vfsmount.
+				    root
+				   /    \
+				  tmp    usr
+
+		    And we want to replicate the tree at multiple
+		    mountpoints under /root/tmp
+
+		step2:
+		      mount --make-shared /root
+
+		      mkdir -p /tmp/m1
+
+		      mount --rbind /root /tmp/m1
+
+		      the new tree now looks like this:
+
+				    root
+				   /    \
+				 tmp    usr
+				/
+			       m1
+			      /  \
+			     tmp  usr
+			     /
+			    m1
+
+			  it has two vfsmounts
+
+		step3:
+			    mkdir -p /tmp/m2
+			    mount --rbind /root /tmp/m2
+
+			the new tree now looks like this:
+
+				      root
+				     /    \
+				   tmp     usr
+				  /    \
+				m1       m2
+			       / \       /  \
+			     tmp  usr   tmp  usr
+			     / \          /
+			    m1  m2      m1
+				/ \     /  \
+			      tmp usr  tmp   usr
+			      /        / \
+			     m1       m1  m2
+			    /  \
+			  tmp   usr
+			  /  \
+			 m1   m2
+
+		       it has 6 vfsmounts
+
+		step 4:
+			  mkdir -p /tmp/m3
+			  mount --rbind /root /tmp/m3
+
+			  I wont' draw the tree..but it has 24 vfsmounts
+
+
+		at step i the number of vfsmounts is V[i] = i*V[i-1].
+		This is an exponential function. And this tree has way more
+		mounts than what we really needed in the first place.
+
+		One could use a series of umount at each step to prune
+		out the unneeded mounts. But there is a better solution.
+		Unclonable mounts come in handy here.
+
+		step 1:
+		   lets say the root tree has just two directories with
+		   one vfsmount.
+				    root
+				   /    \
+				  tmp    usr
+
+		    How do we set up the same tree at multiple locations under
+		    /root/tmp
+
+		step2:
+		      mount --bind /root/tmp /root/tmp
+
+		      mount --make-rshared /root
+		      mount --make-unbindable /root/tmp
+
+		      mkdir -p /tmp/m1
+
+		      mount --rbind /root /tmp/m1
+
+		      the new tree now looks like this:
+
+				    root
+				   /    \
+				 tmp    usr
+				/
+			       m1
+			      /  \
+			     tmp  usr
+
+		step3:
+			    mkdir -p /tmp/m2
+			    mount --rbind /root /tmp/m2
+
+		      the new tree now looks like this:
+
+				    root
+				   /    \
+				 tmp    usr
+				/   \
+			       m1     m2
+			      /  \     / \
+			     tmp  usr tmp usr
+
+		step4:
+
+			    mkdir -p /tmp/m3
+			    mount --rbind /root /tmp/m3
+
+		      the new tree now looks like this:
+
+				    	  root
+				      /    	  \
+				     tmp    	   usr
+			         /    \    \
+			       m1     m2     m3
+			      /  \     / \    /  \
+			     tmp  usr tmp usr tmp usr

+	->mnt_master
+
+	->mnt_share links togather all the mount to/from which this vfsmount
+		send/receives propagation events.
+
+	->mnt_slave_list links all the mounts to which this vfsmount propagates
+		to.
+
+	->mnt_slave links togather all the slaves that its master vfsmount
+		propagates to.
+
+	->mnt_master points to the master vfsmount from which this vfsmount
+		receives propagation.
+
+	->mnt_flags takes two more flags to indicate the propagation status of
+		the vfsmount.  MNT_SHARE indicates that the vfsmount is a shared
+		vfsmount.  MNT_UNCLONABLE indicates that the vfsmount cannot be
+		replicated.
+
+	All the shared vfsmounts in a peer group form a cyclic list through
+	->mnt_share.
+
+	All vfsmounts with the same ->mnt_master form on a cyclic list anchored
+	in ->mnt_master->mnt_slave_list and going through ->mnt_slave.
+
+	 ->mnt_master can point to arbitrary (and possibly different) members
+	 of master peer group.  To find all immediate slaves of a peer group
+	 you need to go through _all_ ->mnt_slave_list of its members.
+	 Conceptually it's just a single set - distribution among the
+	 individual lists does not affect propagation or the way propagation
+	 tree is modified by operations.
+
+	A example propagation tree looks as shown in the figure below.
+	[ NOTE: Though it looks like a forest, if we consider all the shared
+	mounts as a conceptual entity called 'pnode', it becomes a tree]
+
+
+		        A <--> B <--> C <---> D
+		       /|\	      /|      |\
+		      / F G	     J K      H I
+		     /
+		    E<-->K
+			/|\
+		       M L N
+
+	In the above figure  A,B,C and D all are shared and propagate to each
+	other.   'A' has got 3 slave mounts 'E' 'F' and 'G' 'C' has got 2 slave
+	mounts 'J' and 'K'  and  'D' has got two slave mounts 'H' and 'I'.
+	'E' is also shared with 'K' and they propagate to each other.  And
+	'K' has 3 slaves 'M', 'L' and 'N'
+
+	A's ->mnt_share links with the ->mnt_share of 'B' 'C' and 'D'
+
+	A's ->mnt_slave_list links with ->mnt_slave of 'E', 'K', 'F' and 'G'
+
+	E's ->mnt_share links with ->mnt_share of K
+	'E', 'K', 'F', 'G' have their ->mnt_master point to struct
+				vfsmount of 'A'
+	'M', 'L', 'N' have their ->mnt_master point to struct vfsmount of 'K'
+	K's ->mnt_slave_list links with ->mnt_slave of 'M', 'L' and 'N'
+
+	C's ->mnt_slave_list links with ->mnt_slave of 'J' and 'K'
+	J and K's ->mnt_master points to struct vfsmount of C
+	and finally D's ->mnt_slave_list links with ->mnt_slave of 'H' and 'I'
+	'H' and 'I' have their ->mnt_master pointing to struct vfsmount of 'D'.
+
+
+	NOTE: The propagation tree is orthogonal to the mount tree.
+
+
+8B Algorithm:
+
+	The crux of the implementation resides in rbind/move operation.
+
+	The overall algorithm breaks the operation into 3 phases: (look at
+	attach_recursive_mnt() and propagate_mnt())
+
+	1. prepare phase.
+	2. commit phases.
+	3. abort phases.
+
+	Prepare phase:
+
+	for each mount in the source tree:
+		   a) Create the necessary number of mount trees to
+		   	be attached to each of the mounts that receive
+			propagation from the destination mount.
+		   b) Do not attach any of the trees to its destination.
+		      However note down its ->mnt_parent and ->mnt_mountpoint
+		   c) Link all the new mounts to form a propagation tree that
+		      is identical to the propagation tree of the destination
+		      mount.
+
+		   If this phase is successful, there should be 'n' new
+		   propagation trees; where 'n' is the number of mounts in the
+		   source tree.  Go to the commit phase
+
+		   Also there should be 'm' new mount trees, where 'm' is
+		   the number of mounts to which the destination mount
+		   propagates to.
+
+		   if any memory allocations fail, go to the abort phase.
+
+	Commit phase
+		attach each of the mount trees to their corresponding
+		destination mounts.
+
+	Abort phase
+		delete all the newly created trees.
+
+	NOTE: all the propagation related functionality resides in the file
+	pnode.c
