Merge branch 'sched-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

* 'sched-v28-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (38 commits)
  sched debug: add name to sched_domain sysctl entries
  sched: sync wakeups vs avg_overlap
  sched: remove redundant code in cpu_cgroup_create()
  sched_rt.c: resch needed in rt_rq_enqueue() for the root rt_rq
  cpusets: scan_for_empty_cpusets(), cpuset doesn't seem to be so const
  sched: minor optimizations in wake_affine and select_task_rq_fair
  sched: maintain only task entities in cfs_rq->tasks list
  sched: fixup buddy selection
  sched: more sanity checks on the bandwidth settings
  sched: add some comments to the bandwidth code
  sched: fixlet for group load balance
  sched: rework wakeup preemption
  CFS scheduler: documentation about scheduling policies
  sched: clarify ifdef tangle
  sched: fix list traversal to use _rcu variant
  sched: turn off WAKEUP_OVERLAP
  sched: wakeup preempt when small overlap
  kernel/cpu.c: create a CPU_STARTING cpu_chain notifier
  kernel/cpu.c: Move the CPU_DYING notifiers
  sched: fix __load_balance_iterator() for cfq with only one task
