due to an off-by-one bug in the L1TF patch, the "rare" case of systems still vulnerable
is more frequent.

This typically happens on Nehalem+ destop/entry-level server systems with 32G memory installed.

Originally this was reported in OpenSUSE, but I can confirm this is also happens
with the latest trusty kernel (3.13.0-157-generic)

The following patch increases the memory limit for the mitigation on these systems in general:
