sched: only update rq->clock while holding rq->lock Vatsa noticed rq->clock going funny and tracked it down to an update_rq_clock() outside a rq->lock section. This is a problem because things like double_rq_lock() update the rq->clock value for both rqs. Therefore disabling interrupts isn't strong enough.
