Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar: "The main changes in this cycle are: - 'Nested Sleep Debugging', activated when CONFIG_DEBUG_ATOMIC_SLEEP=y. This instruments might_sleep() checks to catch places that nest blocking primitives - such as mutex usage in a wait loop. Such bugs can result in hard to debug races/hangs. Another category of invalid nesting that this facility will detect is the calling of blocking functions from within schedule() -> sched_submit_work() -> blk_schedule_flush_plug(). There's some potential for false positives (if secondary blocking primitives themselves are not ready yet for this facility), but the kernel will warn once about such bugs per bootup, so the warning isn't much of a nuisance. This feature comes with a number of fixes, for problems uncovered with it, so no messages are expected normally. - Another round of sched/numa optimizations and refinements, for CONFIG_NUMA_BALANCING=y. - Another round of sched/dl fixes and refinements. Plus various smaller fixes and cleanups" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (54 commits) sched: Add missing rcu protection to wake_up_all_idle_cpus sched/deadline: Introduce start_hrtick_dl() for !CONFIG_SCHED_HRTICK sched/numa: Init numa balancing fields of init_task sched/deadline: Remove unnecessary definitions in cpudeadline.h sched/cpupri: Remove unnecessary definitions in cpupri.h sched/deadline: Fix rq->dl.pushable_tasks bug in push_dl_task() sched/fair: Fix stale overloaded status in the busiest group finding logic sched: Move p->nr_cpus_allowed check to select_task_rq() sched/completion: Document when to use wait_for_completion_io_*() sched: Update comments about CLONE_NEWUTS and CLONE_NEWIPC sched/fair: Kill task_struct::numa_entry and numa_group::task_list sched: Refactor task_struct to use numa_faults instead of numa_* pointers sched/deadline: Don't check CONFIG_SMP in switched_from_dl() sched/deadline: Reschedule from switched_from_dl() after a successful pull sched/deadline: Push task away if the deadline is equal to curr during wakeup sched/deadline: Add deadline rq status print sched/deadline: Fix artificial overrun introduced by yield_task_dl() sched/rt: Clean up check_preempt_equal_prio() sched/core: Use dl_bw_of() under rcu_read_lock_sched() sched: Check if we got a shallowest_idle_cpu before searching for least_loaded_cpu ...
