    Pull scheduler changes from Ingo Molnar:
     "Major changes:
    
       - Reworked CPU capacity code, for better SMP load balancing on
         systems with assymetric CPUs. (Vincent Guittot, Morten Rasmussen)
    
       - Reworked RT task SMP balancing to be push based instead of pull
         based, to reduce latencies on large CPU count systems. (Steven
         Rostedt)
    
       - SCHED_DEADLINE support updates and fixes. (Juri Lelli)
    
       - SCHED_DEADLINE task migration support during CPU hotplug. (Wanpeng Li)
    
       - x86 mwait-idle optimizations and fixes. (Mike Galbraith, Len Brown)
    
       - sched/numa improvements. (Rik van Riel)
    
       - various cleanups"
