Subject: [PATCH 0/2] KVM: x86/pmu: do not mask the value that is written to fixed PMUs

The first patch is a small refactoring to enforce masking of values
returned by RDPMC and RDMSR.  The second patch fix pmu_intel.c to
behave the same as real hardware; this fixes the failing tests
introduced in kvm-unit-tests by "x86: PMU: Fix PMU counters masking".

(Nadav, this is just FYI.  I am not CCing you on individual patches
to avoid problems with your corporate overlords, and I am not expecting
a review from you).
