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.
