Merge branch 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull CPU hotplug updates from Ingo Molnar:
"Two changes in this cycle:
- Make the /sys/devices/system/cpu/smt/* files available on all
arches, so user space has a consistent way to detect whether SMT is
enabled.
- Sparse annotation fix"
* 'smp-hotplug-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
smpboot: Place the __percpu annotation correctly
cpu/hotplug: Create SMT sysfs interface for all arches
