Subject[GIT PULL] scheduler updates
Linus,

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

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

# HEAD: 82845079160817cc6ac64e5321bbd935e0a47b3a Merge branch 'linus' into sched/urgent, to resolve conflicts

This tree includes the following changes:

- membarrier updates (Mathieu Desnoyers)

- SMP balancing optimizations (Mel Gorman)

- stats update optimizations (Peter Zijlstra)

- RT scheduler race fixes (Steven Rostedt)

- misc fixes and updates

Note: I merged in a (tested) version of your tree to resolve three separate
conflicts, two trivial, the third one a bit more complex - but feel free to pull
the original sha1 before the merge as well.

Thanks,

Ingo
