* Add more checks when writing VPMU control registers
* Explicitly disable PEBS since calculating reserved bits in
MSR_IA32_PEBS_ENABLE
is somewhat non-trivial (and pointless since PEBS is not supported)
Boris Ostrovsky (2):
x86/VPMU: Check more carefully which bits are allowed to be written
to MSRs
x86/VPMU: Don't allow any non-zero writes to MSR_IA32_PEBS_ENABLE
