Linus Torvalds: Linux 2.6.8-rc4

Kernel.org
Mirrors

Full Changelog

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.
