Linux 2.5.4-dj1

Linux 2.5.4-dj1

[Dave Jones]

Mostly compile fixes, and a point-release resync.
Diffsize hasn't come down as much as I expected, so I'll push a few
of the larger chunks to Linus tomorrow.

Patch against 2.5.4 vanilla is available from:
ftp://ftp.kernel.org/pub/linux/kernel/people/davej/patches/2.5/

I ended up sending the following patch to Linus instead.

Would you merge this into your next release, so we can keep the trees in
sync (and not inadvertently push your fix over Linus's later on).  This
approach removes the conditional altogether in the UP+preempt case, so
it is optimal.

Thanks,
