Merge branch 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull SMP/hotplug updates from Thomas Gleixner:
 "A small set of updates for SMP and CPU hotplug:

   - Abort disabling secondary CPUs in the freezer when a wakeup is
     pending instead of evaluating it only after all CPUs have been
     offlined.

   - Remove the shared annotation for the strict per CPU cfd_data in the
     smp function call core code.

   - Remove the return values of smp_call_function() and on_each_cpu()
     as they are unconditionally 0. Fixup the few callers which actually
     bothered to check the return value"

* 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  smp: Remove smp_call_function() and on_each_cpu() return values
  smp: Do not mark call_function_data as shared
  cpu/hotplug: Abort disabling secondary CPUs if wakeup is pending
  cpu/hotplug: Fix notify_cpu_starting() reference in bringup_wait_for_ap()
