3.16.68-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Tim Chen <tim.c.chen@linux.intel.com>
commit 8eb729b77faf83ac4c1f363a9ad68d042415f24c upstream.
"Reduced Data Speculation" is an obsolete term. The correct new name is "Speculative store bypass disable" - which is abbreviated into SSBD.
