- The faster copy_*_user patch for Intel ia32 CPUs has been updated to
  be a little faster.

- A few 2.5.43 compilation fixes are included.

- Ingo's get_unmapped_area() speedup is added

- Included the extended attributes and posix ACL code.  This feature
  is late, IMO.  People who want this would be advised to help shake
  it down.

- There are still a few problems with the shared pagetable code.  One
  of David's fixup patches didn't work out, so there are two followup
  patches over in the experimental/ directory.  They're for David - don't
  use them.

- There's a little tweak here (no-reclaim-throttle.patch) which will
  improve interactivity on small machines during heavy writeout.

  But generally, for those people who have had problems with sluggishness
  and swappiness in the 2.5 VM: 2.5.43 pretty much has it all.  Please
  give it a shot.

  /proc/sys/vm/swappiness is available for playing with.  Default value
  is 60%, and 100 gives you the previous 2.5 behaviour.

  Some things are slower - most notably things which involve simultaneous
  reading from and writing to the same disk.  Such workloads were traded
  off against latency under write loads.  I expect that with careful attention
  some of this can be pulled back, but it's not a large regression.  Maybe
  up to 10-20%.
