    Linus Torvalds authored
    Pull core SMP updates from Thomas Gleixner:
     "CPU (hotplug) updates:
    
       - Support for locked CSD objects in smp_call_function_single_async()
         which allows to simplify callsites in the scheduler core and MIPS
    
       - Treewide consolidation of CPU hotplug functions which ensures the
         consistency between the sysfs interface and kernel state. The low
         level functions cpu_up/down() are now confined to the core code and
         not longer accessible from random code"
