[Lucid] SRU: Update to 2.6.32.23

[Brad Figg]

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/649483

SRU Justification

Impact:

The upstream process for stable tree updates is quite similar in scope
to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a
bug, and each patch is vetted by upstream by originating either directly
from Linus' tree or in a minimally backported form of that patch.

The 2.6.32.23 upstream stable patch set is now available. It should be
included in the Ubuntu kernel as well.
