    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 are:
    
       - lockless wakeup support for futexes and IPC message queues
         (Davidlohr Bueso, Peter Zijlstra)
    
       - Replace spinlocks with atomics in thread_group_cputimer(), to
         improve scalability (Jason Low)
    
       - NUMA balancing improvements (Rik van Riel)
    
       - SCHED_DEADLINE improvements (Wanpeng Li)
    
       - clean up and reorganize preemption helpers (Frederic Weisbecker)
    
       - decouple page fault disabling machinery from the preemption
         counter, to improve debuggability and robustness (David
         Hildenbrand)
    
       - SCHED_DEADLINE documentation updates (Luca Abeni)
    
       - topology CPU masks cleanups (Bartosz Golaszewski)
    
       - /proc/sched_debug improvements (Srikar Dronamraju)"
    
    * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (79 commits)

      sched/deadline: Make init_sched_dl_class() __init
      sched/deadline: Optimize pull_dl_task()
      sched/preempt: Add static_key() to preempt_notifiers
      sched/preempt: Fix preempt notifiers documentation about hlist_del() within unsafe iteration
      sched/stop_machine: Fix deadlock between multiple stop_two_cpus()
      sched/debug: Add sum_sleep_runtime to /proc/<pid>/sched
      sched/debug: Replace vruntime with wait_sum in /proc/sched_debug
      sched/debug: Properly format runnable tasks in /proc/sched_debug

      sched/fair: Prevent throttling in early pick_next_task_fair()
      preempt: Reorganize the notrace definitions a bit
      preempt: Use preempt_schedule_context() as the official tracing preemption point
      sched: Make preempt_schedule_context() function-tracing safe
