[PATCH] cpuidle: Measure idle state durations with monotonic clock

Hi all,

The code looks correct and inviting to me as it has led to good cleanups.
I dont think passing 0 as the argument to the function
should lead to problems,as it does not do anything useful with the
passed arguments.

My only curiosity is what was the purpose of passing idle residency time to
sched_clock_idle_wakeup_event() when this data could always be retrieved from
dev->last_residency for each cpu,which gets almost immediately updated.

But this does not seem to come in way of this patch for now.Anyway I
have added Peter to
the list so that he can opine about this issue if possible and needed.
