For the purposes of review and testing, this is going to be hard to pick
apart and compare. It doesn't apply against 3.7-rc5 and when trying to
resolve the conflicts it quickly becomes obvious that the series depends
on other scheduler patches such as

sched: Add an rq migration call-back to sched_class
sched: Introduce temporary FAIR_GROUP_SCHED dependency for load-tracking

This is not a full list, it was just the first I hit. What are the other
scheduler patches you are depend on? Knowing that will probably help pick
apart some of the massive patches like "sched, numa, mm: Add adaptive
NUMA affinity support" which is a massive monolithic patch I have not even
attempted to read yet but the diffstat for it alone says a lot.
