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()
