Ingo Molnar 2cd4d0ea19 [PATCH] sched: make cpu_clock() not use the rq clock 
it is enough to disable interrupts to get the precise rq-clock
of the local CPU.

this also solves an NMI watchdog regression: the NMI watchdog
calls touch_softlockup_watchdog(), which might deadlock on
rq->lock if the NMI hits an rq-locked critical section.
