Like Xu 30dab5c0b6 KVM: x86/pmu: Reject userspace attempts to set reserved GLOBAL_STATUS bits 
Reject userspace writes to MSR_CORE_PERF_GLOBAL_STATUS that attempt to set
reserved bits.  Allowing userspace to stuff reserved bits doesn't harm KVM
itself, but it's architecturally wrong and the guest can't clear the
unsupported bits, e.g. makes the guest's PMI handler very confused.
