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
