Subject: [PATCH] cpufreq: governors: implement generic policy_is_shared
Date: Thu, 31 Jan 2013 09:14:24 +0100 [thread overview]
Message-ID: <1359620064-14751-1-git-send-email-fabio.baltieri@linaro.org> (raw)
Implement a generic helper function policy_is_shared() to replace the
current dbs_sw_coordinated_cpus() at cpufreq level, so that it can be
used by code other than cpufreq governors.
Suggested-by: Viresh Kumar <viresh.kumar@linaro.org>
