Subject: [RFC PATCH 0/2] sched: move content out of core files for load average

Recent activity has had a focus on moving functionally related blocks of stuff
out of sched/core.c into stand-alone files.  The code relating to load average
calculations has grown significantly enough recently to warrant placing it in
a separate file.

Here we do that, and in doing so, we shed ~20k of code from sched/core.c (~10%).

A couple small static functions in the core sched.h header were also localized
to their singular user in sched/fair.c at the same time, with the goal to also
reduce the amount of "broadcast" content in that sched.h file.

Paul.

[ Patches sent here are tested on tip's sched/core, i.e. v3.9-rc1-38-gb329fd5

  Assuming that this change is OK with folks, the timing can be whatever is most
  convenient -- i.e. I can update/respin it close to the end of the merge window
  for what will be v3.10-rc1, if that is what minimizes the inconvenience to folks
  who might be changing the code that is relocated here. ]

Paul Gortmaker (2):
  sched: fork load calculation code from sched/core --> sched/load_avg
  sched: move update_load_[add/sub/set] from sched.h to fair.c
