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 |.......................................................................... | pre 30 41 118 645 3769 6214 12233 14312 | post 299 603 1211 2418 4697 6847 11606 14557 | | 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its size sched: Improve scalability via 'CPU buddies', which withstand random perturbations cpusets: Remove/update outdated comments cpusets, hotplug: Restructure functions that are invoked during hotplug cpusets, hotplug: Implement cpuset tree traversal in a helper function CPU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
