[PATCH 5/5] cpufreq: Use cpufreq_policy_list for iterating over policies

From: Viresh Kumar
Date: Tue Aug 20 2013 - 02:41:09 EST


To iterate over all policies we currently iterate over all CPUs and
then get the policy for each of them. Let's use the newly created
cpufreq_policy_list for this purpose.
