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

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.

  Revert "sched/fair: Drop always true parameter of
    update_cfs_rq_load_avg()"
  sched/fair: Skip frequency update if CPU about to idle
  cpufreq: schedutil: Use idle_calls counter of the remote CPU
  sched/fair: Correct obsolete comment about cpufreq_update_util
  sched/fair: remove impossible condition from find_idlest_group_cpu
