Subject: Re: [PATCH 6/7] Cpuidle: Deal with timer expiring in the past

NAK

tick_nohz_get_sleep_length() has exactly 1 consumer -- cpuidle.

Rather than have cpuidle second guess what is returned,
tick_nohz_get_sleep_length() should be updated to return a value
that makes sense to cpuidle.

thanks,
