Hi

With an ARM Landing Team branch based on LSK 3.18 Android I'm seeing a hang if I

After bisecting, I fixed this problem by reverting commit 553b785b5383 ("cpufreq: Iterate over all the possible cpus to create powerstats.")

So in this patch I believe instead of "for_each_possible_cpu" we should use "for_each_online_cpu". Can you please re-enable this patch and try this change?

I was tempted to also revert the other scheduler and cpufreq mods from Google that are part of the same series, just as a precaution, because they don't fill me with confidence, but have left them in for now.
