Subject[PATCH 4.14 080/146] x86/speculation: Update the TIF_SSBD comment
Date
4.14-stable 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.
