Merge branch 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git...

Pull x86 apic updates from Ingo Molnar:
 "The main changes are:

   - Persistent CPU/node numbering across CPU hotplug/unplug events.
     This is a pretty involved series of changes that first fetches all
     the information during bootup and then uses it for the various
     hotplug/unplug methods. (Gu Zheng, Dou Liyang)

   - IO-APIC hot-add/remove fixes and enhancements. (Rui Wang)

   - ... various fixes, cleanups and enhancements"
