[PATCH 0/5][Trusty][CVE-2016-2069] Race condition in arch/x86/mm/tlb.c

[Luis Henriques]

Following this email I am sending the backport of the fix for
CVE-2016-2069.  This backport is based on a backport I've done before for
the stable 3.16 (hence the comment in the commit summary referring to this
kernel version).

This CVE is fixed in all the other ubuntu kernels, only Trusty is missing
it.

Obviously, the actual fix is just the 1st patch; I'm sending the 2nd for
completeness.
