    Pull scheduler updates from Ingo Molnar:
     "The main scheduler changes in this cycle were:
    
       - support Intel Turbo Boost Max Technology 3.0 (TBM3) by introducig a
         notion of 'better cores', which the scheduler will prefer to
         schedule single threaded workloads on. (Tim Chen, Srinivas
         Pandruvada)
    
       - enhance the handling of asymmetric capacity CPUs further (Morten
         Rasmussen)
    
       - improve/fix load handling when moving tasks between task groups
         (Vincent Guittot)
    
       - simplify and clean up the cputime code (Stanislaw Gruszka)
    
       - improve mass fork()ed task spread a.k.a. hackbench speedup (Vincent
         Guittot)
    
       - make struct kthread kmalloc()ed and related fixes (Oleg Nesterov)
    
       - add uaccess atomicity debugging (when using access_ok() in the
         wrong context), under CONFIG_DEBUG_ATOMIC_SLEEP=y (Peter Zijlstra)
    
       - implement various fixes, cleanups and other enhancements (Daniel
         Bristot de Oliveira, Martin Schwidefsky, Rafael J. Wysocki)"
