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.
Additionally, the following patch was applied to 2.6.35.6 upstream
stable as a combination of two upstream commits which required
additional backporting. We'd already applied this commit as 3 separate
clean upstream cherry-picks so I've chosen to skip the stable patch in
favor of the cleaner upstream cherry-picks:
* intel_agp, drm/i915: Add all sandybridge graphics devices support
The following patches are in the 2.6.35.6 stable release:
