Merge branch 'smp-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull SMP hotplug fixes from Thomas Gleixner: "Two fixlets for cpu hotplug: - Fix a subtle ordering problem with the dummy timer. This happened to work before the conversion by chance due to initcall ordering. - Fix the function comment for __cpuhp_setup_state()" * 'smp-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: cpu/hotplug: Clarify description of __cpuhp_setup_state() return value clocksource/dummy_timer: Move hotplug callback after the real timers
