KVM: ignore reads from AMDs C1E enabled MSR
If the Linux kernel detects an C1E capable AMD processor (K8 RevF and higher), it will access a certain MSR on every attempt to go to halt. Explicitly handle this read and return 0 to let KVM run a Linux guest with the native AMD host CPU propagated to the guest. Signed-off-by:Andre Przywara <andre.przywara@amd.com> Signed-off-by:
