    Linus Torvalds authored
    Pull scheduler updates from Ingo Molnar:
     "The main changes are:
    
       - Migrate CPU-intense 'misfit' tasks on asymmetric capacity systems,
         to better utilize (much) faster 'big core' CPUs. (Morten Rasmussen,
         Valentin Schneider)
    
       - Topology handling improvements, in particular when CPU capacity
         changes and related load-balancing fixes/improvements (Morten
         Rasmussen)
    
       - ... plus misc other improvements, fixes and updates"
