Jian Jun Chen 1d194ede61 hv: support reference time enlightenment ... Two time related synthetic MSRs are implemented in this patch. Both of them are partition wide MSR. - HV_X64_MSR_TIME_REF_COUNT is read only and it is used to return the partition's reference counter value in 100ns units. - HV_X64_MSR_REFERENCE_TSC is used to set/get the reference TSC page, a sequence number, an offset and a multiplier are defined in this page by hypervisor and guest OS can use them to calculate the normalized reference time since partition creation, in 100ns units.
