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

The following upstream stable patches were skipped due to non trivial revert issues:
* drm/i915: add 'reclaimable' to i915 self-reclaimable page allocations
* drm/i915: fix hibernation since i915 self-reclaim fixes
* drm: stop information leak of old kernel stack.
The following upstream stable patches were skipped due to having been previously applied as a CVE:
* can: add limit for nframes and clean up signed/unsigned variables
