Enable a few new cpu features including UMONITOR, UMWAIT, TPAUSE,
MOVDIRI and MOVDIR64B.
UMONITOR, UMWAIT, and TPAUSE are a set of user wait instructions.
MOVDIRI moves doubleword or quadword from register to memory through
direct store.
MOVDIR64B moves 64-bytes as direct-store with 64-bytes write atomicity.
Do you have corresponding KVM changes?
Paolo
