Use a common X86_FEATURE_* flag for AMD's PSFD, and suppress it from /proc/cpuinfo via the standard method of an empty string instead of hacking in a one-off "private" #define in KVM. The request that led to KVM defining its own flag was really just that the feature not show up in /proc/cpuinfo, and additional patches+discussions in the interim have clarified that defining flags in cpufeatures.h purely so that KVM can advertise features to userspace is ok so long as the kernel already uses a word to track the associated CPUID leaf. No functional change intended.
