Title:
  Saucy update to 3.11.6 stable release

Status in “linux” package in Ubuntu:
  New
Status in “linux” source package in Saucy:
  New

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

         git://git.kernel.org/

      TEST CASE: TBD
