Pull x86 apic updates from Dave Hansen:
 "This includes a very thorough rework of the 'struct apic' handlers.
  Quite a variety of them popped up over the years, especially in the
  32-bit days when odd apics were much more in vogue.

  The end result speaks for itself, which is a removal of a ton of code
  and static calls to replace indirect calls.

  If there's any breakage here, it's likely to be around the 32-bit
  museum pieces that get light to no testing these days.

  Summary:

   - Rework apic callbacks, getting rid of unnecessary ones and
     coalescing lots of silly duplicates.

   - Use static_calls() instead of indirect calls for apic->foo()

   - Tons of cleanups an crap removal along the way"
