[PATCH V2 10/19] tick-common: call tick_check_percpu() from tick_check_preferred()

From: Viresh Kumar
Date: Mon Apr 21 2014 - 06:00:08 EST


tick_check_percpu() and tick_check_preferred() are called from two places and in
exactly same order. So, would make sense to call tick_check_percpu() from
tick_check_preferred() instead, so that their caller can just call
tick_check_preferred().
