5a059f1ac0 [ARM] Add more syscalls
Add:
  sys_unshare
  sys_set_robust_list
  sys_get_robust_list
  sys_splice
  sys_arm_sync_file_range
  sys_tee
  sys_vmsplice
  sys_move_pages
  sys_getcpu

Special note about sys_arm_sync_file_range(), which is implemented as:

asmlinkage long sys_arm_sync_file_range(int fd, unsigned int flags,
                                        loff_t offset, loff_t nbytes)
{
        return sys_sync_file_range(fd, offset, nbytes, flags);
}

We can't export sys_sync_file_range() directly on ARM because the
argument list someone picked does not fit in the available registers.
Would be nice if... there was an arch maintainer review mechanism for
new syscalls before they hit the kernel.

* We provide pm_suspend() to avoid unresolved symbols in apm.o. We are
unable to truly suspend now, hence the stub.

* Speaker/microphone enabling got removed because it will be placed in the alsa driver.

5cbded585d [PATCH] getting rid of all casts of k[cmz]alloc() calls

	  echo "De-casting $f..."
	  perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
	done

And then go through and reinstate those cases where code is casting pointers
to non-pointers.

And then drop a few hunks which conflicted with outstanding work.

More fixes to build breakage from the work_struct changes ...  this updates

NOTE that until the i2c core gets fixed to work without SMBUS_QUICK,
kernels needing this driver must still use "tps65010.force=0,0x48" on the

f0d1b0b30d [PATCH] LOG2: Implement a general integer log2 facility in the kernel
This facility provides three entry points:

	ilog2()		Log base 2 of unsigned long
	ilog2_u32()	Log base 2 of u32
	ilog2_u64()	Log base 2 of u64

These facilities can either be used inside functions on dynamic data:

	int do_something(long q)
	{
		...;
		y = ilog2(x)
		...;
	}

Or can be used to statically initialise global variables with constant values:

	unsigned n = ilog2(27);

When performing static initialisation, the compiler will report "error:
initializer element is not constant" if asked to take a log of zero or of
something not reducible to a constant.  They treat negative numbers as
unsigned.

When not dealing with a constant, they fall back to using fls() which permits
them to use arch-specific log calculation instructions - such as BSR on
x86/x86_64 or SCAN on FRV - if available.

7174d85260 [ARM] 3983/2: remove unused argument to __bug()
It appears that include/asm-arm/bug.h requires include/linux/stddef.h
for the definition of NULL. It seems that stddef.h was always included
indirectly in most cases, and that issue was properly fixed a while ago.

Then commit 5047f09b56 incorrectly reverted
change from commit ff10952a54 (bad dwmw2)
and the problem recently resurfaced.

Because the third argument to __bug() is never used anyway, RMK suggested
getting rid of it entirely instead of readding #include <linux/stddef.h>
which this patch does.

285f5fa7e9 [ARM] 3995/1: iop13xx: add iop13xx support
The iop348 processor integrates an Xscale (XSC3 512KB L2 Cache) core with a
Serial Attached SCSI (SAS) controller, multi-ported DDR2 memory
controller, 3 Application Direct Memory Access (DMA) controllers, a 133Mhz
PCI-X interface, a x8 PCI-Express interface, and other peripherals to form
a system-on-a-chip RAID subsystem engine.

The iop342 processor replaces the SAS controller with a second Xscale core
for dual core embedded applications.

The iop341 processor is the single core version of iop342.

This patch supports the two Intel customer reference platforms iq81340mc
for external storage and iq81340sc for direct attach (HBA) development.

The developer's manual is available here:

db68b189f4 [PATCH] add rtc-omap driver
This creates a new RTC-framework driver for the RTC/calendar module found
in various OMAP1 chips.  (OMAP2 and OMAP3 use external RTCs, like those in
TI's multifunction PM companion chips.) It's been in the Linux-OMAP tree
for several months now, and other trees before that, so it's quite stable.
The most notable issue is that the OMAP IRQ code doesn't yet support the
RTC IRQ as a wakeup event.  Once that's fixed, a patch will be needed.

afe4b25e7d [ARM] 3881/4: xscale: clean up cp0/cp1 handling
XScale cores either have a DSP coprocessor (which contains a single
40 bit accumulator register), or an iWMMXt coprocessor (which contains
eight 64 bit registers.)

Because of the small amount of state in the DSP coprocessor, access to
the DSP coprocessor (CP0) is always enabled, and DSP context switching
is done unconditionally on every task switch.  Access to the iWMMXt
coprocessor (CP0/CP1) is enabled only when an iWMMXt instruction is
first issued, and iWMMXt context switching is done lazily.

CONFIG_IWMMXT is supposed to mean 'the cpu we will be running on will
have iWMMXt support', but boards are supposed to select this config
symbol by hand, and at least one pxa27x board doesn't get this right,
so on that board, proc-xscale.S will incorrectly assume that we have a
DSP coprocessor, enable CP0 on boot, and we will then only save the
first iWMMXt register (wR0) on context switches, which is Bad.

This patch redefines CONFIG_IWMMXT as 'the cpu we will be running on
might have iWMMXt support, and we will enable iWMMXt context switching
if it does.'  This means that with this patch, running a CONFIG_IWMMXT=n
kernel on an iWMMXt-capable CPU will no longer potentially corrupt iWMMXt
state over context switches, and running a CONFIG_IWMMXT=y kernel on a
non-iWMMXt capable CPU will still do DSP context save/restore.

These changes should make iWMMXt work on PXA3xx, and as a side effect,
enable proper acc0 save/restore on non-iWMMXt capable xsc3 cores such
as IOP13xx and IXP23xx (which will not have CONFIG_CPU_XSCALE defined),
as well as setting and using HWCAP_IWMMXT properly.

fcc63716a5 [ARM] 3957/1: AT91: Physically mapped flash on DK and EK boards
This patch converts the old CONFIG_MTD_PHYSMAP_ options to the new
physmap API by creating a physmap platform device for the NOR flash
found on the Atmel AT91RM9200-DK and AT91RM9200-EK boards.

122214428a [ARM] 3911/2: Simplify alloc_thread_info on ARM
Remove ARM local cache of 4 struct thread_info.
Can cause oops under certain circumstances.

Russell indicated the original optimization was
required on older kernels to avoid thread starvation
on memory fragmentation, but may no longer be
required.  I've updated the patch to 19rc4 and
ensured no <config.h> dain-bramage slipped in this
time (sorry about that).

Original description follows:

I was given some test results which pointed to an
Oops in alloc_thread_info (happened 2x), and after
looking at the code, I see that ARM has its own
local cache of 4 struct thread_info. There wasn't
any clear (to me) synchronization between the
alloc_thread_info and the free_thread_info.

I looked over the other arch, and they all simply
allocate them on an as needed basis, so I simplified
the ARM to do the same, based on the other arch
(e.g. PPC) and the folks doing the testing have
indicated that this fixed the oops.

5e70982750 [ARM] 3927/1: Allow show_mem() to work with holes in memory map.
show_mem() was not correctly handling holes in the memory
map.  It was treating the freed sections of the map as
though they contained valid struct page entries.  This
could cause incorrect debugging output or even a kernel
panic.

This patch keeps the struct meminfo around after system
initialization so that show_mem() can use it when
scanning memory.  show_mem() now walks over each bank
of each online node, rather than assuming that each node
contains a single contiguous bank.

984d115bbf [ARM] 3918/1: ixp4xx irq-chip rework
This is a rework of the ixp4xx irq_chip implementation.  The use of
two irq_chip structures and potentially switching between them is a
violation of the intended use of the IRQ framework.  The current
implementation does not work with current in-kernel spinlock debugging
or lockdep due to lock recursion problems caused by calling
set_irq_chip/handler from within the chip's set_irq_type().

This patch goes back to using one irq_chip structure and handling the
differences between edge/level, normal/GPIO interrupts inside the
ack/mask/unmask routines themselves.

75d3521377 [PATCH] atmel_serial: Pass fixed register mappings through platform_data
In order to initialize the serial console early, the atmel_serial
driver had to do a hack where it compared the physical address of the
port with an address known to be permanently mapped, and used it as a
virtual address. This got around the limitation that ioremap() isn't
always available when the console is being initalized.

This patch removes that hack and replaces it with a new "regs" field
in struct atmel_uart_data that the board-specific code can initialize
to a fixed virtual mapping for platform devices where this is possible.
It also initializes the DBGU's regs field with the address the driver
used to check against.

On AVR32, the "regs" field is initialized from the physical base
address when this it can be accessed through a permanently 1:1 mapped
segment, i.e. the P4 segment.

If regs is NULL, the console initialization is delayed until the "real"
driver is up and running and ioremap() can be used.

Add the ability to have pxafb use only certain fixed video modes

Following this, add support for the cxx00 QVGA mode. Mode information
is passed to the lcd_power call to allowing the panel drivers to
configure the display hardware accordingly (corgi_lcd already contains
the functionality for the cxx00 panel).

This mirrors the setup already used by w100fb.

So we can kill wall_jiffies completely.

This is just a cleanup and logically should not change any real behavior
except for one thing: RTC updating code in (old) ppc and xtensa use a
condition "jiffies - wall_jiffies == 1".  This condition is never met so I
suppose it is just a bug.  I just remove that condition only instead of
kill the whole "if" block.

2552fc27ff [ARM] 3809/3: get rid of 4 megabyte kernel image size limit
We currently have a hardcoded 4 megabyte uncompressed kernel image
size limit, which is easily exceeded by, for example, enabling some of
the various kernel debugging options.

When setting up the initial page tables (which is where this 4M limit
is hardcoded), it's actually relatively easy to find out the true size
of the uncompressed kernel image and create enough page table entries
for things to fit, so this patch makes it so.

In the decompressor, we also need to know the size of the uncompressed
kernel image, to figure out whether there is any chance that uncompressing
the kernel might overwrite the compressed kernel image stored elsewhere
in memory. We don't have that info at this boot stage, though, so we
approximate the size of the uncompressed kernel by taking the compressed
kernel image size and allowing for a maximum 4x expansion.

3171a0305d [PATCH] simplify update_times (avoid jiffies/jiffies_64 aliasing problem)
Pass ticks to do_timer() and update_times(), and adjust x86_64 and s390
timer interrupt handler with this change.

Currently update_times() calculates ticks by "jiffies - wall_jiffies", but
callers of do_timer() should know how many ticks to update.  Passing ticks
get rid of this redundant calculation.  Also there are another redundancy
pointed out by Martin Schwidefsky.

This cleanup make a barrier added by
5aee405c66 needless.  So this patch removes
it.

As a bonus, this cleanup make wall_jiffies can be removed easily, since now
wall_jiffies is always synced with jiffies.  (This patch does not really
remove wall_jiffies.  It would be another cleanup patch)

f400e198b2 [PATCH] pidspace: is_init()
This is an updated version of Eric Biederman's is_init() patch.
(http://lkml.org/lkml/2006/2/6/280).  It applies cleanly to 2.6.18-rc3 and
replaces a few more instances of ->pid == 1 with is_init().

Further, is_init() checks pid and thus removes dependency on Eric's other
patches for now.

Eric's original description:

	There are a lot of places in the kernel where we test for init
	because we give it special properties.  Most  significantly init
	must not die.  This results in code all over the kernel test
	->pid == 1.

	Introduce is_init to capture this case.

	With multiple pid spaces for all of the cases affected we are
	looking for only the first process on the system, not some other
	process that has pid == 1.

df67b3daea [PATCH] make PROT_WRITE imply PROT_READ
Make PROT_WRITE imply PROT_READ for a number of architectures which don't
support write only in hardware.

While looking at this, I noticed that some architectures which do not
support write only mappings already take the exact same approach.  For
example, in arch/alpha/mm/fault.c:

"
        if (cause < 0) {
                if (!(vma->vm_flags & VM_EXEC))
                        goto bad_area;
        } else if (!cause) {
                /* Allow reads even for write-only mappings */
                if (!(vma->vm_flags & (VM_READ | VM_WRITE)))
                        goto bad_area;
        } else {
                if (!(vma->vm_flags & VM_WRITE))
                        goto bad_area;
        }
"

Thus, this patch brings other architectures which do not support write only
mappings in-line and consistent with the rest.  I've verified the patch on
ia64, x86_64 and x86.

Additional discussion:

Several architectures, including x86, can not support write-only mappings.
The pte for x86 reserves a single bit for protection and its two states are
read only or read/write.  Thus, write only is not supported in h/w.

Currently, if i 'mmap' a page write-only, the first read attempt on that page
creates a page fault and will SEGV.  That check is enforced in
arch/blah/mm/fault.c.  However, if i first write that page it will fault in
and the pte will be set to read/write.  Thus, any subsequent reads to the page
will succeed.  It is this inconsistency in behavior that this patch is
attempting to address.  Furthermore, if the page is swapped out, and then
brought back the first read will also cause a SEGV.  Thus, any arbitrary read
on a page can potentially result in a SEGV.

According to the SuSv3 spec, "if the application requests only PROT_WRITE, the
implementation may also allow read access." Also as mentioned, some
archtectures, such as alpha, shown above already take the approach that i am
suggesting.

The counter-argument to this raised by Arjan, is that the kernel is enforcing
the write only mapping the best it can given the h/w limitations.  This is
true, however Alan Cox, and myself would argue that the inconsitency in
behavior, that is applications can sometimes work/sometimes fails is highly
undesireable.  If you read through the thread, i think people, came to an
agreement on the last patch i posted, as nobody has objected to it...

In nommu mode, the exception vector location depends on the platforms.
Some of the implementations may have some special exception control
forwarding method in their ROM/flash and for some of them has its own
re-mapping mechanism by the h/w.

This patch introduces a special configuration CONFIG_CPU_HIGH_VECTOR which
turns on the CR_V bit in nommu mode. The CR_V bit is turned off by default.

b2bbb20b37 USB: pxa2xx_udc understands GPIO based VBUS sensing
This updates the PXA 25x UDC board-independent infrastructure for VBUS sensing
and the D+ pullup.  The original code evolved from rather bizarre support on
Intel's "Lubbock" reference hardware, so that on more sensible hardware it
doesn't work as well as it could/should.

The change is just to teach the UDC driver how to use built-in PXA GPIO pins
directly.  This reduces the amount of board-specfic object code needed, and
enables the use of a VBUS sensing IRQ on boards (like Gumstix) that have one.
With VBUS sensing, the UDC is unclocked until a host is actually connected.

fefdaa06cc [ARM] nommu: defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU
By merging of uClinux/ARM, we need to treat various CPU cores which have
MMU, MPU or even none for memory management. The memory management
coprocessors are controlled by CP15 register set and the ARM core family
can be categorized by 5 groups by the register ;
  G-a. CP15 is MMU : 610, 710, 720, 920, 922, 925, 926, 1020, 1020e, 1022,
		v6 and the derivations sa1100, sa110, xscale, xsc3.
  G-b. CP15 is MPU : 740, 940, 946, 996, 1156.
  G-c. CP15 is MPU or MMU : 1026 (selectable by schematic design)
  G-d. CP15 is exist, but nothing for memory managemnt : 966, 968.
  G-e. no-CP15 : 7tdmi, 9tdmi, 9e, 9ej

This patch defines CPU_CP15, CPU_CP15_MMU and CPU_CP15_MPU. Thus the
family can be defined as :
  - CPU_CP15 only : G-d
  - CPU_CP15_MMU(implies CPU_CP15) : G-a, G-c(selectable)
  - CPU_CP15_MPU(implies CPU_CP15) : G-b, G-c(selectable)
  - !CPU_CP15 : G-e

46a82b2d55 [PATCH] Standardize pxx_page macros
One of the changes necessary for shared page tables is to standardize the
pxx_page macros.  pte_page and pmd_page have always returned the struct
page associated with their entry, while pte_page_kernel and pmd_page_kernel
have returned the kernel virtual address.  pud_page and pgd_page, on the
other hand, return the kernel virtual address.

Shared page tables needs pud_page and pgd_page to return the actual page
structures.  There are very few actual users of these functions, so it is
simple to standardize their usage.

Since this is basic cleanup, I am submitting these changes as a standalone
patch.  Per Hugh Dickins' comments about it, I am also changing the
pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.
