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

* 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  x86, ioapic: Print IR_IO_APIC_route_entry when IR is enabled
  x86, ioapic: Print IRTE when IR is enabled
  x86, x2apic: Preserve high 32-bits of IA32_APIC_BASE MSR
  x86, ioapic: Also print Dest field
  x86, ioapic: Format clean up for IOAPIC output
  x86: print APIC data a little later during boot
