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. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
