From b43a7ffbf33be7e4d3b10b7714ee663ea2c52fe2 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Sun, 24 Mar 2013 11:56:43 +0530 Subject: cpufreq: Notify all policy->cpus in cpufreq_notify_transition() policy->cpus contains all online cpus that have single shared clock line. And their frequencies are always updated together. Many SMP system's cpufreq drivers take care of this in individual drivers but the best place for this code is in cpufreq core. This patch modifies cpufreq_notify_transition() to notify frequency change for all cpus in policy->cpus and hence updates all users of this API.
