Maverick update to 2.6.35.6 stable release

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