    Merge branch 'smp-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
    
    Pull CPU hotplug fix from Thomas Gleixner:
     "A single fix preventing the concurrent execution of the CPU hotplug
      callback install/invocation machinery. Long standing bug caused by a
      massive brain slip of that Gleixner dude, which went unnoticed for
      almost a year"
