2.5.32-mm4

[Andrew Morton <akpm@zip.com.au>]

http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.32/2.5.32-mm4/

Since -mm2:

- Linus has merged a bunch of things.  Of which O_DIRECT support for ext3
  is the only interesting part.

- mm3 was a temp syncup with wli.  mm4 has survived an overnight deathtest
  and looks pretty good.

+ the block-highmem scsi fix has been changed: we now allow block-highmem
  for all scsi devices, not just disks.

+ added a patch to move the rmap locking functions into their own
  header file.

+ highpte is now working.

  There is no evidence that non-ia32 people have tried to compile this
  code yet.

+ a race in slablru has been fixed.  slablru seems to keep the slabs
  under control quite nicely.

+ added rml's low-latency-zap_page_range patch

+ reinstated buffermem acounting in /proc/meminfo.  This is useful,
  but the implementation's walk across the inode_unused list will
  probably be very costly in some situations.  May need to change it so
  that the inode walk only works correctly for blockdevs, or make
  the inode_unused list (and inode_lock!) per-superblock.

+ The configurable kernel/userspace split patch is back.

+ Added Rohit's ia32 huge tlb page patch.  We don't have any tools
  to test this with at present, which is a bit of a problem.

+ Added Jani Monoses' EXT3_SB cleanup.
