Merge branch 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 apic updates from Ingo Molnar:
"The main changes in this cycle were:
- introduce optimized single IPI sending methods on modern APICs
(Linus Torvalds, Thomas Gleixner)
- kexec/crash APIC handling fixes and enhancements (Hidehiro Kawai)
- extend lapic vector saving/restoring to the CMCI (MCE) vector as
well (Juergen Gross)
- various fixes and enhancements (Jake Oshins, Len Brown)"
