3.16.7-ckt7 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Alex Deucher <alexander.deucher@amd.com>

commit a124d068bf5be6be2ff4b9fab77b1b7509107e68 upstream.

Should be the same as cayman.  We don't use VM by default
on NI parts so this isn't critical.
