Wysocki" , Viresh Kumar , linux-pm@vger.kernel.org It is pure mystery to me why we need to be on a specific CPU while looking up a value in an array. My best shot at this is that before commit d4019f0a92ab ("cpufreq: move freq change notifications to cpufreq core") it was required to invoke cpufreq_notify_transition() on a special CPU. Since it looks like a waste, remove it. Cc: "Rafael J.
