6783fe6253 [MIPS] Wire up the timerfd_*() o32 system calls
This patch enables the system calls timerfd_create(), timerfd_settime()
and timerfd_gettime() for MIPS architecture.

Please see the following Bugzilla entry for more details:

http://bugzilla.kernel.org/show_bug.cgi?id=10038

This was tested using a Malta 4Kc board in both little-endian and
big-endian modes. The unit test program is available from the URL
above.

2eaa7ec286 [MIPS] Handle I-cache coherency in flush_cache_range()
So far flush_cache_range() did't consider the I-cache largely because it
did rarely ever matter to real world code.  This was working primarily
because normally code and data are don't share the same pages - with the
exception of MIPS16 code which uses address constants embedded between
the code.   The following sequence of events may break the code:

 o MIPS16 executable being loaded
 o dynamic linker relocates the address constants embedded into the code:
 o   Uses mprotect(2) to make code pages PROT_READ|PROT_WRITE
 o   Performs the actual relocations by writing to the pages which likely
     are COW.  Because no PROT_EXEC is set I-cache coherence will not be
     considered.
 o   Uses mprotect(2) to switch code pages back to PROT_READ|PROT_EXEC.
     This results in a call to flush_cache_range() which also does not
     consider I-caches.
 o => executing the page just having been relocated may now result in the
   I-cache getting refilled with stale data from memory.

14e04c3f6e ide-cd: fix missing residual count setting in DMA mode
This patch fixes the missing residual count setting in DMA mode,
which was introduced during the conversion to blk-end-request.
The residual count could be used by the request submitter.
So if it isn't set correctly, some upper layers does not work.
(e.g. wodim for CD burning.)

The bug is in only DMA mode.
In PIO mode, we are setting the residual count correctly,
so no need to fix.

0e7d8d4802 ht6560b: force prefetch for some devices
Prefetch needs to be set for some ide devices to work when connected to
a ht6560b interface. This was not always done properly, causing a system
with a HD and CD on the primary interface to not work properly. Or, in
effect, hang hard.

This patch forces prefetch on devices before checking whether it
is necessary to change the settings in the interface

This patch should also be applied to 2.4. I don't currently have a
2.4 tree around.

31eedd823c x86: zap invalid and unused pmds in early boot
The early boot code maps KERNEL_TEXT_SIZE (currently 40MB) starting
from __START_KERNEL_map. The kernel itself only needs _text to _end
mapped in the high alias. On relocatible kernels the ASM setup code
adjusts the compile time created high mappings to the relocation. This
creates invalid pmd entries for negative offsets:

0xffffffff80000000 -> pmd entry: ffffffffff2001e3
It points outside of the physical address space and is marked present.

This starts at the virtual address __START_KERNEL_map and goes up to
the point where the first valid physical address (0x0) is mapped.

Zap the mappings before _text and after _end right away in early
boot. This removes also the invalid entries.

Furthermore it simplifies the range check for high aliases.

51af33e8e4 RDMA/nes: Fix possible array overrun
In nes_create_qp(), the test

	if (nesqp->mmap_sq_db_index > NES_MAX_USER_WQ_REGIONS) {

is used to error out if the db_index is too large; however, if the
test doesn't trigger, then the index is used as

	nes_ucontext->mmap_nesqp[nesqp->mmap_sq_db_index] = nesqp;

and mmap_nesqp is declared as

	struct nes_qp      *mmap_nesqp[NES_MAX_USER_WQ_REGIONS];

which leads to an array overrun if the index is exactly equal to
NES_MAX_USER_WQ_REGIONS.  Fix this by bailing out if the index is
greater than or equal to NES_MAX_USER_WQ_REGIONS.

This was spotted by the Coverity checker (CID 2162).

7c018804c0 V4L/DVB (7197): bttv: Fix overlay divide error
The initial work to convert the bttv driver to V4L2 "Partial conversion
from V4L1 to V4L2" (e84619b174), missed
the line which set the appropriate overlay crop structure in the newly
allocated bttv_buffer.  This then causes a divide error in the
bttv_calc_geo function.

27d0fe1894 V4L/DVB (7194): cx88-mpeg: Allow concurrent access to cx88-mpeg devices
It currently isn't possible to open the frontend device of cx88-mpeg devices
(DVB or Blackbird) multiple times concurrently. (for instance, to attach a
signal monitoring tool while reading a stream, or to send a frequency change
ioctl) This patch fixes that condition.

5caf51342c V4L/DVB (7188): radio-si470x version 1.0.6
This patch combines all the finished discussions and its resulting patches from
the mailing list.

The version 1.0.6 is mainly influenced by Oliver Neukum. He found a lot of
small issues, that are fixed with this patch now. For me the most interesting
thing is, that it's now safer to use it on other architectures.

The history for version 1.0.6 is:
- fixed coverity checker warnings in *_usb_driver_disconnect
- probe()/open() race by correct ordering in probe()
- DMA coherency rules by separate allocation of all buffers
- use of endianness macros
- abuse of spinlock, replaced by mutex
- racy handling of timer in disconnect, replaced by delayed_work
- racy interruptible_sleep_on(), replaced with wait_event_interruptible()
- handle signals in read()

The driver is tested with all Debian/testing radio programs and rdsd. The patch
is tested against checkpatch.pl v1.12.
