-Subject: x86: add a synthetic TSC_RELIABLE feature bit
-Patch-mainline:
-References: bnc#441338
-
-Impact: None, bit reservation only
-
-Add a synthetic TSC_RELIABLE feature bit which will be used to mark
-TSC as reliable so that we could skip all the runtime checks for
-TSC stablity, which have false positives in virtual environment.
