Bug description:
  SRU Justification

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



         The following patches are in the stable release:
