Nope.  All of the places that it gets used here are in
initialization-time paths.  The two we have here are when kvm and the
host are setting up a new vcpu and when the kvmclock clocksource is
being registered.  A CPU getting hotplugged is the only thing that might
even have these get called more than at boot.
