Subject: [PATCH 07/10] cpuidle: Remove unnecessary current_clr_polling() on poll_idle()
There is no point in clearing TIF_NR_POLLING and folding TIF_NEED_RESCHED
upon poll_idle() exit because cpuidle_idle_call() is going to set again
TIF_NR_POLLING anyway. Also if TIF_NEED_RESCHED is set, it will be
folded and TIF_NR_POLLING will be cleared at the end of do_idle().
