I don't see spurious wake-ups with only hotplug operations.

So we'll have to reconsider if that patch is still needed once we merge
the cpuidle driver.  It certainly won't go into mainline in its current 
form in any case.

I do hope it is not required though -- that should be the job of the 
firmware.
