[PATCH RFC v1 05/18] clocksource/hyperv: use MSR-based access if running as root
...be available to the root partition (as
HV_MSR_REFERENCE_TSC_AVAILABLE is set), why don't we use it? (I
understand that with TSC scaling support in modern CPUs even migration
is a no-issue and we can use raw TSC but this all seems to be
independent from root/non-root partition question).
