Title:
  Trusty update to v3.13.11-ckt34 stable release

Status in linux package in Ubuntu:
  Confirmed
Status in linux source package in Trusty:
  Fix Committed

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 a mainline/stable Linux tree or
         a minimally backported form of that patch. The v3.13.11-ckt34 upstream stable
         patch set is now available. It should be included in the Ubuntu
         kernel as well.

         git://kernel.ubuntu.com/ubuntu/linux.git

      TEST CASE: TBD

         The following patches from the v3.13.11-ckt34 stable release
