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

# 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
