[PATCH V2 0/3] improve -overcommit cpu-pm=on|off

Currently, if running "-overcommit cpu-pm=on" on hosts that don't have MWAIT support, the MWAIT/MONITOR feature is advertised to the guest and executing MWAIT/MONITOR on the guest triggers #UD. V2: - [PATCH 1]: took Thomas' suggestion for more generic fix - [PATCH 2/3]: no c
