John Allen d0671151c2 kvm/svm: PKU not currently supported ... commit a47970ed74 upstream. Current SVM implementation does not have support for handling PKU. Guests running on a host with future AMD cpus that support the feature will read garbage from the PKRU register and will hit segmentation faults on boot as memory is getting marked as protected that should not be. Ensure that cpuid from SVM does not advertise the feature.
