Paolo Bonzini 095cf55df7 KVM: x86: Hyper-V tsc page setup ... Lately tsc page was implemented but filled with empty values. This patch setup tsc page scale and offset based on vcpu tsc, tsc_khz and HV_X64_MSR_TIME_REF_COUNT value. The valid tsc page drops HV_X64_MSR_TIME_REF_COUNT msr reads count to zero which potentially improves performance.
