Subject: [PATCH 12/38] tick-common: call tick_check_percpu() from tick_check_preferred()
Date: Mon, 14 Apr 2014 21:53:34 +0530	[thread overview]
Message-ID: <3dc98fbdafb209e105b42925770da2884da8237e.1397492345.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1397492345.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1397492345.git.viresh.kumar@linaro.org>

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 common caller can just call
tick_check_preferred().
