Pull x86 fixes from Ingo Molnar:
 "Half of the fixes are for various build time warnings triggered by
  randconfig builds. Most (but not all...) were harmless.

  There's also:

   - ACPI boundary condition fixes

   - UV platform fixes

   - defconfig updates

   - an AMD K6 CPU init fix

   - a %pOF printk format related preparatory change

   - .. and a warning fix related to the tlb/PCID changes"
