Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (25 commits) sched: Fix SCHED_MC regression caused by change in sched cpu_power sched: Don't use possibly stale sched_class kthread, sched: Remove reference to kthread_create_on_cpu sched: cpuacct: Use bigger percpu counter batch values for stats counters percpu_counter: Make __percpu_counter_add an inline function on UP sched: Remove member rt_se from struct rt_rq sched: Change usage of rt_rq->rt_se to rt_rq->tg->rt_se[cpu] sched: Remove unused update_shares_locked() sched: Use for_each_bit sched: Queue a deboosted task to the head of the RT prio queue sched: Implement head queueing for sched_rt sched: Extend enqueue_task to allow head queueing sched: Remove USER_SCHED sched: Fix the place where group powers are updated sched: Assume *balance is valid sched: Remove load_balance_newidle() sched: Unify load_balance{,_newidle}() sched: Add a lock break for PREEMPT=y sched: Remove from fwd decls sched: Remove rq_iterator from move_one_task ... Fix up trivial conflicts in kernel/sched.c
