x86/cpufeature: Enable RING3MWAIT for Knights Landing Enable ring 3 MONITOR/MWAIT for Intel Xeon Phi x200 codenamed Knights Landing. Presence of this feature cannot be detected automatically (by reading any other MSR) therefore it is required to explicitly check for the family and model of the CPU before attempting to enable it.
