sched: fix rq->clock warps on frequency changes
sched: fix rq->clock warps on frequency changes Fix 2bacec8c318ca0418c0ee9ac662ee44207765dd4 (sched: touch softlockup watchdog after idling) that reintroduced warps on frequency changes. touch_softlockup_watchdog() calls __update_rq_clock that checks rq->clock for warps, so call it after adjusting rq->clock.
