  KVM: x86: omit "impossible" pmu MSRs from MSR list (2019-10-04 14:01:28 +0200)

----------------------------------------------------------------
ARM and x86 bugfixes of all kinds.  The most visible one is that migrating
a nested hypervisor has always been busted on Broadwell and newer processors,
and that has finally been fixed.
