KVM: SVM: support writing 0 to K8 performance counter control registers
This lets SVM ignore writes of the value 0 to the performance counter control
registers. Thus enabling them will still fail in the guest, but a write of 0
which keeps them disabled is accepted. This is required to boot Windows
Vista 64bit.
