Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler changes from Ingo Molnar:
"The biggest change is a performance improvement on SMP systems:
| 4 socket 40 core + SMT Westmere box, single 30 sec tbench
| runs, higher is better:
|
| clients 1 2 4 8 16 32 64 128

| A nice increase in performance.
which speedup is particularly noticeable on heavily interacting
few-tasks workloads, so the changes should help desktop-style Xorg
workloads and interactivity as well, on multi-core CPUs.
There are also cpuset suspend behavior fixes/restructuring and various
smaller tweaks."
* 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
sched: Fix race in task_group()
sched: Improve balance_cpu() to consider other cpus in its group as target of (pinned) task
sched: Reset loop counters if all tasks are pinned and we need to redo load balance
sched: Reorder 'struct lb_env' members to reduce its size
sched: Improve scalability via 'CPU buddies', which withstand random perturbations
cpusets: Remove/update outdated comments
cpusets, hotplug: Restructure functions that are invoked during hotplug
cpusets, hotplug: Implement cpuset tree traversal in a helper function
CPU hotplug, cpusets, suspend: Don't modify cpusets during suspend/resume
sched/x86: Remove broken power estimation
