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 v4.2.8 upstream stable
       patch set is now available. It should be included in the Ubuntu
       kernel as well.



       The following patches are in the v4.2.8 stable release:
