Linux 2.6.8-rc4

[Linus Torvalds]

Hmm.. Not a huge amount of changes, but enough that I wouldn't have felt
comfortable releasing it as 2.6.8. I've been hoping to resolve the dcache
reports, and we found _one_ bug, but that one would likely not affect a
whole lot of people, so..

Some ARM updates, the i586 AES code rewrite, some ppc updates.. A large 
portion of the patch actually ends up being cleaning up some /proc files 
(thanks to Al for doing seq-file conversions) and me fixing some broken 
calling conventions in sysctl and sound /proc handling.

The shortlog gives a reasonable picture of the changes.
