e52e15d3c1 [PATCH] sstfb: fix pixclock setting on Voodoo 1/2 cards
Pixclock setting in sstfb didn't work with my Voodoo 2 card with ICS 5342 DAC
(this DAC requires two consecutive writes to one of its registers to program
pixclock - maybe first write merged with second).

28735a7253 [PATCH] gpio_direction_output() needs an initial value
It's been pointed out that output GPIOs should have an initial value, to
avoid signal glitching ...  among other things, it can be some time before
a driver is ready.  This patch corrects that oversight, fixing

 - documentation
 - platforms supporting the GPIO interface
 - users of that call (just one for now, others are pending)

There's only one user of this call for now since most platforms are still
using non-generic GPIO setup code, which in most cases already couples the
initial value with its "set output mode" request.

Note that most platforms are clear about the hardware letting the output
value be set before the pin direction is changed, but the s3c241x docs are
vague on that topic ...  so those chips might not avoid the glitches.

a836f5856a [PATCH] spi: destroy workqueue after spi_unregister_master
Fix a bug in the cleanup of an spi_bitbang bus.

The workqueue associated with the bus was destroyed before the call to
spi_unregister_master.  That meant that spi devices on that bus would be
unable to do IO in their remove method.  The shutdown flag should have been
able to prevent a segfault, but was never getting set.  By waiting to
destroy the workqueue until after the master is unregistered, devices are
able to do IO in their remove methods.  An added benefit is that neither
the shutdown flag nor a wait for the queue of messages to empty is needed.

65b8291c40 [PATCH] dio: invalidate clean pages before dio write
This patch fixes a user-triggerable oops that was reported by Leonid
Ananiev as archived at http://lkml.org/lkml/2007/2/8/337.

dio writes invalidate clean pages that intersect the written region so that
subsequent buffered reads go to disk to read the new data.  If this fails
the interface tries to tell the caller that the cache is inconsistent by
returning EIO.

Before this patch we had the problem where this invalidation failure would
clobber -EIOCBQUEUED as it made its way from fs/direct-io.c to fs/aio.c.
Both fs/aio.c and bio completion call aio_complete() and we reference freed
memory, usually oopsing.

This patch addresses this problem by invalidating before the write so that
we can cleanly return -EIO before ->direct_IO() has had a chance to return
-EIOCBQUEUED.

There is a compromise here.  During the dio write we can fault in mmap()ed
pages which intersect the written range with get_user_pages() if the user
provided them for the source buffer.  This is a crazy thing to do, but we
can make it mostly work in most cases by trying the invalidation again.
The compromise is that we won't return an error if this second invalidation
fails if it's an AIO write and we have -EIOCBQUEUED.

This was tested by having two processes race performing large O_DIRECT and
buffered ordered writes.  Within minutes ext3 would see a race between
ext3_releasepage() and jbd holding a reference on ordered data buffers and
would cause invalidation to fail, panicing the box.  The test can be found
in the 'aio_dio_bugs' test group in test.kernel.org/autotest.  After this
patch the test passes.

4b25a37e20 [PATCH] ufs: zeroize the rest of block in truncate
This patch fix behaviour in such test scenario:

  lseek(fd, BIG_OFFSET)
  write(fd, buf, sizeof(buf))
  truncate(BIG_OFFSET)
  truncate(BIG_OFFSET + sizeof(buf))
  read(fd, buf...)

Because of if file big enough(BIG_OFFSET) we start allocate space by block,
ordinary block size > page size, so we should zeroize the rest of block in
truncate(except last framgnet, about which VFS should care), to not get
garbage, when we extend file.

Also patch corrects conversion from pointer to block to physical block number,
this helps in case of not common used UFS types.

And add to debug output inode number.

2189850f42 [PATCH] ufs2: more correct work with time
This patch corrects work with time in UFS2 case.

1) According to UFS2 disk layout modification/access and so on "time"
   should be hold in two variables one 64bit for seconds and another 32bit for
   nanoseconds,

   at now for some unknown reason we suppose that "inode time" holds in
   three variables 32bit for seconds, 32bit for milliseconds and 32bit for
   nanoseconds.

2) We set amount of nanoseconds in "VFS inode" to 0 during read, instead of
   getting values from "on disk inode"(this should close
   http://bugzilla.kernel.org/show_bug.cgi?id=7991).

d1acb4210a [SPARC64]: Get DEBUG_PAGEALLOC working again.
We have to make sure to use base-pagesize TLB entries even during the
early transition period where we need TLB miss handling but don't have
the kernel page tables setup yet for the linear region.

Also, it is necessary therefore to not use the 4MB TSB for these
translations, and instead use the normal kernel TSB.  This allows us
to also get rid of the 4MB tsb for debug builds which shrinks the
kernel a little bit.

The ipv6_fl_socklist from listening socket is inadvertently shared
with new socket created for connection.  This leads to a variety of
interesting, but fatal, bugs. For example, removing one of the
sockets may lead to the other socket's encountering a page fault
when the now freed list is referenced.

The fix is to not share the flow label list with the new socket.

The warnings does not show up during a normal build due to kbuild
failing to check for section mismatch in vmlinux.
To see these warnings run:
scripts/mod/modpost arch/x86_64/kernel/built-in.o

kbuild will be fixed but the 'noise-level' had to be decresed first.
There remains a few section mismatch warnigns for x86_64 for areas where I did
not feel confident.

From the HDA spec it appears that the buffers written to the BDL and

e7b0d26a86 [PATCH] sysfs: reinstate exclusion between method calls and attribute unregistration
This patch (as869) reinstates the mutual exclusion between sysfs
attribute method calls and attribute unregistration.  The
previously-reported deadlocks have been fixed, and this exclusion is
by far the simplest way to avoid races during driver unbinding.

The check for orphaned read-buffers has been moved down slightly, so
that the remainder of a partially-read buffer will still be available
to userspace even after the attribute has been unregistered.

d9a9cdfb07 [PATCH] sysfs and driver core: add callback helper, used by SCSI and S390
This patch (as868) adds a helper routine for device drivers that need
to set up a callback to perform some action in a different process's
context.  This is intended for use by attribute methods that want to
unregister themselves or their parent device.  Attribute method calls
are mutually exclusive with unregistration, so such actions cannot be
taken directly.

Two attribute methods are converted to use the new helper routine: one
for SCSI device deletion and one for System/390 ccwgroup devices.

0803c30c23 [ARM] 4264/1: ldrex/strex syntax errors with recent compilers
Trying to build some code using atomic_clear_mask() on a ARM v6
processor with a recent compiler (tried with gcc version 4.1.1
(CodeSourcery ARM Sourcery G++ 2006q3-26), but
all gcc > 4.1 might be affected) results in the following:

/tmp/ccWKLJV8.s: Assembler messages:
/tmp/ccWKLJV8.s:581: Error: instruction does not accept this addressing
mode -- `ldrex r0,r3'
/tmp/ccWKLJV8.s:583: Error: instruction does not accept this addressing
mode -- `strex r1,r0,r3'

Older gcc (like gcc version 4.0.0 (DENX ELDK 4.1 4.0.0)) have no problem
with this.

The patch below fixes the compile error. I also verified that gcc-4.0.0 generates identical code using both forms.

This patch fixes the poll routine for the natsemi driver so that if the

069f825636 natsemi: Fix NAPI for interrupt sharing
The interrupt status register for the natsemi chips is clear on read and
was read unconditionally from both the interrupt and from the NAPI poll
routine, meaning that if the interrupt service routine was called (for
example, due to a shared interrupt) while a NAPI poll was scheduled
interrupts could be missed.  This patch fixes that by ensuring that the
interrupt status register is only read by the interrupt handler when
interrupts are enabled from the chip.

It also reverts a workaround for this problem from the netpoll hook and
improves the trace for interrupt events.

Thanks to Sergei Shtylyov <sshtylyov@ru.mvista.com> for spotting the
issue, Mark Huth <mhuth@mvista.com> for a simpler method and Simon
Blake <simon@citylink.co.nz> for testing resources.

14fdd90ef2 natsemi: Consistently use interrupt enable/disable functions
The natsemi drivers include functions for enabling and disabling
interrupts from the chip but these are not used in all code paths.  This
patch changes the code paths that touch the interrupt enable register to
use the functions.  In all cases this adds an extra PCI read to post the
operation but since none of these are in fast paths this shouldn't be
too much of a problem.
