Patch looks good to me. Thanks Tim.

I expect this will also improve other pm-qos users, but of course they
are likely not as frequently used as the idle governour.

(and before anyone makes jokes about optimizing the idle loop: idle 
latency is very important for workloads with lots of wakeups out of
idle)
