Tao Xu 6e3ba4abce KVM: vmx: Emulate MSR IA32_UMWAIT_CONTROL ... UMWAIT and TPAUSE instructions use 32bit IA32_UMWAIT_CONTROL at MSR index E1H to determines the maximum time in TSC-quanta that the processor can reside in either C0.1 or C0.2. This patch emulates MSR IA32_UMWAIT_CONTROL in guest and differentiate IA32_UMWAIT_CONTROL between host and guest. The variable mwait_control_cached in arch/x86/kernel/cpu/umwait.c caches the MSR value, so this patch uses it to avoid frequently rdmsr of IA32_UMWAIT_CONTROL.
