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

* 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  x86: Skip cpus with apic-ids >= 255 in !x2apic_mode
  x86, x2apic: Allow "nox2apic" to disable x2apic mode setup by BIOS
  x86, x2apic: Fallback to xapic when BIOS doesn't setup interrupt-remapping
  x86, acpi: Skip acpi x2apic entries if the x2apic feature is not present
  x86, apic: Add probe() for apic_flat
  x86: Simplify code by removing a !SMP #ifdefs from 'struct cpuinfo_x86'
  x86: Convert per-cpu counter icr_read_retry_count into a member of irq_stat
  x86: Add per-cpu stat counter for APIC ICR read tries
  pci, x86/io-apic: Allow PCI_IOAPIC to be user configurable on x86
  x86: Fix the !CONFIG_NUMA build of the new CPU ID fixup code support
  x86: Add NumaChip support
  x86: Add x86_init platform override to fix up NUMA core numbering
  x86: Make flat_init_apic_ldr() available
