2.5.40-mm1

[Andrew Morton <akpm@digeo.com>]

url: http://www.zip.com.au/~akpm/linux/patches/2.5/2.5.40/2.5.40-mm1/

Mainly a resync.

- A few minor problems in the per-cpu-pages code have been fixed.

- Updated dcache RCU code.

- Significant brain surgery on the SARD patch.

- Decreased the disk scheduling tunable `fifo_batch' from 32 to 16 to
  improve disk read latency.

- Updated ext3 htree patch from Ted.

- Included a patch from Mala Anand which _should_ speed up kernel<->userspace
  memory copies for Intel ia32 hardware.  But I can't measure any difference
  with poorly-aligned pagecache copies.
