Linux 2.5.1-dj2

Dave Jones: “Keeping the ball rolling.. Fix up some merge errors, scoop
up another bunch of pending fixes, and back out some problem bits
for now.”

Patch is available from:
http://www.codemonkey.org.uk/patches/2.5/patch-2.5.1-dj2.diff.bz2

Some of these fixes still haven't found their way back to Marcelo yet
but should show up in 2.4.17-rc2 / 2.4.18pre1 with any luck.
