Not sure, IIRC we clear that when the TSC sync test fails, eg when we
mark the tsc clocksource unusable.

Worrying. By the time we detect this the guest may already have gotten confused by clocks going backwards.


Upstream, we are marking the TSC unstable preemptively when hardware which will eventually sync test is detected, so this should be fine.

ENOPARSE?
