[PATCH 0/2] KVM: selftests: Fix PMU counters test flakiness

[Sean Christopherson <seanjc@xxxxxxxxxx>]

v2 of Maxim's patch to fix the flakiness with the PMU counters test do to
a single CLFLUSH not guaranteeing an LLC miss.

v2:
 - Add a prep patch to tweak the macros in preparation for moving CLFUSH{,OPT}
   into the loop.
 - Keep the MFENCE (because paranoia doesn't hurt in this case).
