Fix reiserfs_writepage so it doesn't race with data=ordered writes.  This
still has a pending fix to redirty the page when it finds a locked buffer. 
Waiting for Andrew to finish sorting that out on ext3 first.

From: Chris Mason <mason@suse.com>

Repacking a tail might leave a journal handle attached to an unmapped buffer.
 If that buffer gets dirtied again (via mmap for example), the reiserfs
data=ordered code might try to write the dirty unmapped buffer to disk.

The fix is to make sure we remove the journal handle when we unmap buffers.

From: Chris Mason <mason@suse.com>

Enable preallocation for reiserfs_file_write when the write size is smaller
than the default preallocation size.

reiserfs data=ordered support.

From: Chris Mason <mason@suse.com>

reiserfs logging rework, making things much faster for small transactions. 
metadata buffers are dirtied when they are safe to write, so normal kernel
mechanisms can contribute to log cleaning.

From: Chris Mason <mason@suse.com>

reiserfs cleanup, get rid of old debugging code.

From: Chris Mason <mason@suse.com>

reiserfs support for nested transactions.  This originally came from Peter
Braam for 2.4.x and was ported forward by Jeff Mahoney.

ext3 transaction batching has been ineffective since the scheduler changes
forced us to replace the yield() with a schedule().

Using schedule_timeout(1) fixes it up again.  Benchmarking is positive with
wither a 1 or 10 millisecond delay in there, so there appears to be no need
to play around with HZ.

From: Kurt Garloff <garloff@suse.de>

A patch to parse the elf binaries for a PT_GNU_STACK section to set the stack
non-executable if possible.  Most parts have been shamelessly stolen from
Ingo Molnar's more ambitious stackshield
http://people.redhat.com/mingo/exec-shield/exec-shield-2.6.4-C9

The toolchain has meanwhile support for marking the binaries with a
PT_GNU_STACK section wwithout x bit as needed.

If no such section is found, we leave the stack to whatever the arch defaults
to.  If there is one, we explicitly disabled the VM_EXEC bit if no x bit is
found, otherwise explicitly enable.

The attached patch fixes a problem with the 32bit statfs call on NFS file
systems.  Some NFS servers return a value of -1 for the f_files and f_ffree.
The current code would think this is a 64bit value that cannot be converted
to 32bits.  Consequently, the system call would always fail.

The patch adds two special if() to detect a value of -1 for f_files and
f_ffree.

This is a update for the cx88 driver.  There are *lots* of changes:

  * vbi support was added.
  * plenty of fixes for audio support (there are still problems
    through).
  * new cards added.
  * serveral minor tweaks.

This patch updates the documentation for the v4l drivers.

This patch updates the bttv driver.  Changes:

  (1) several card-specific tweaks.
  (2) make software vs. hardware i2c configurable per TV card.
  (3) reinitialize image parameters after chip reset.
  (4) make bttv quite by default on frame drops.
  (5) new insmod option: "debug_latency=1" to enable frame drop
      debug messages.

bttv is quite sensitive to irq latencies, especially when capturing both
video and vbi.  There are several reports about problems due to this, I don't
see that on my machines through.  (5) dumps a stracktrace if the driver
thinks the frame drop is is caused by high latencies as experiment, lets see
whenever that helps ...

Some NFS clients respond badly to a TCP connection being reset immediately

- Always drop the oldest connection - Random Early Drop doesn't really help

arch/sparc64/mm/hugetlbpage.c does not include linux/module.h so
EXPORT_SYMBOL prints out warnings, and since sparc64 Makefiles have
-Werror, the build fails.

From: Olof Johansson <olof@austin.ibm.com>

As discussed on the ppc64 list yesterday and today:

On some ppc64 systems, Open Firmware will give memory device nodes that are
only 16MB in size, instead of the 256MB that our NUMA code currently
expects (see MEMORY_INCREMENT in mmzone.h).

Just changing the defines from 256MB to 16MB makes the table blow up from
32KB to 512KB, so this patch also makes it dynamically allocated based on
actual memory size.  Since all this is done before (well, during) bootmem
init so we need to use lmb_alloc().

Finally, there's no need to use a full int for node ID. Current max is 16
nodes, so a signed char still leaves plenty of room to grow.

From: Ingo Molnar <mingo@elte.hu>

Dave reported that /proc/*/status sometimes shows 101% as LoadAVG, which
makes no sense.

the reason of the bug is slightly incorrect scaling of the load_avg value. 
The patch below fixes this.

From: Arjan van de Ven <arjanv@redhat.com>

Below is a patch to enable 4Kb stacks for x86. The goal of this is to

1) Reduce footprint per thread so that systems can run many more threads
   (for the java people)

2) Reduce the pressure on the VM for order > 0 allocations. We see real life
   workloads (granted with 2.4 but the fundamental fragmentation issue isn't
   solved in 2.6 and isn't solvable in theory) where this can be a problem.
   In addition order > 0 allocations can make the VM "stutter" and give more
   latency due to having to do much much more work trying to defragment

The first 2 bits of the patch actually affect compiler options in a generic
way: I propose to disable the -funit-at-a-time feature from gcc.  With this
enabled (and it's default with -O2), gcc will very agressively inline
functions, which is nice and all for userspace, but for the kernel this makes
us suffer a gcc deficiency more: gcc is extremely bad at sharing stackslots,
for example a situation like this:

if (some_condition)
	function_A();
else
	function_B();

with -funit-at-a-time, both function_A() and _B() might get inlined, however
the stack usage of both functions of the parent function grows the stack
usage of both functions COMBINED instead of the maximum of the two.  Even
with the normal 8Kb stacks this is a danger since we see some functions grow
3Kb to 4Kb of stack use this way.  With 4Kb stacks, 4Kb of stack usage growth
obviously is deadly ;-( but even with 8Kb stacks it's pure lottery.
Disabling -funit-at-a-time also exposes another thing in the -mm tree; the
attribute always_inline is considered harmful by gcc folks in that when gcc
makes a decision to NOT inline a function marked this way, it throws an
error.  Disabling -funit-at-a-time disables some of the agressive inlining
(eg of large functions that come later in the .c file) so this would make
your tree not compile.

The 4k stackness of the kernel is included in modversions, so people don't
load 4k-stack modules into 8k-stack kernels.

At present 4k stacks are selectable in config.  When the feature has settled
in we should remove the 8k option.  This will break the nvidia modules.  But
Fedora uses 4k stacks so a new nvidia driver is expected soon.
