Linus,

Please pull the latest sched-core-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-for-linus

# HEAD: 096aa33863a5e48de52d2ff30e0801b7487944f4 sched/numa: Decay ->wakee_flips instead of zeroing

The main scheduling related changes in this cycle were:

- various sched/numa updates, for better performance

- tree wide cleanup of open coded nice levels

- nohz fix related to rq->nr_running use

- cpuidle changes and continued consolidation to improve the
kernel/sched/idle.c high level idle scheduling logic. As part of
this effort I pulled cpuidle driver changes from Rafael as well.

- standardized idle polling amongst architectures

- continued work on preparing better power/energy aware scheduling

- sched/rt updates

- misc fixlets and cleanups

Thanks,

Ingo
