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

Browse source 
Pull x86 apic updates from Thomas Gleixner:
 "This udpate contains:

   - rework the irq vector array to store a pointer to the irq
     descriptor instead of the irq number to avoid a lookup of the irq
     descriptor in the irq entry path

   - lguest interrupt handling cleanups

   - conversion of the local apic timer to the new clockevent callbacks

   - preparatory changes for the irq argument removal of interrupt flow
     handlers"
