Merge tag 'v3.13' into stable-3.14
Linux 3.13
Conflicts:
security/selinux/hooks.c
Trivial merge issue in selinux_inet_conn_request() likely due to me
including patches that I sent to the stable folks in my next tree
resulting in the patch hitting twice (I think). Thankfully it was an
easy fix this time, but regardless, lesson learned, I will not do that
again.
