[PATCH RFC 0/5] sched and cpufreq fixes/cleanups

[Joel Fernandes <joelaf@google.com>]

Here are some patches that are generally minor changes and I am posting them
together. Patches 1/5 and 2/5 are related to skipping cpufreq updates for the
dequeue of the last task before the CPU enters idle. That's just a rebase of
[1] mostly. Patches 3/5 and 4/5 fix some minor things I noticed after the
remote cpufreq update work. and patch 5/5 is just a small clean up of
find_idlest_group. Let me know your thoughts and thanks. I've based these
patches on peterz's queue.git master branch.
