Merge branch 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

* 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (25 commits)
  x86: Fix out of order of gsi
  x86: apic: Fix mismerge, add arch_probe_nr_irqs() again
  x86, irq: Keep chip_data in create_irq_nr and destroy_irq
  xen: Remove unnecessary arch specific xen irq functions.
  smp: Use nr_cpus= to set nr_cpu_ids early
  x86, irq: Remove arch_probe_nr_irqs
  sparseirq: Use radix_tree instead of ptrs array
  sparseirq: Change irq_desc_ptrs to static
  init: Move radix_tree_init() early
  irq: Remove unnecessary bootmem code
  x86: Add iMac9,1 to pci_reboot_dmi_table
  x86: Convert i8259_lock to raw_spinlock
  x86: Convert nmi_lock to raw_spinlock
  x86: Convert ioapic_lock and vector_lock to raw_spinlock
  x86: Avoid race condition in pci_enable_msix()
  x86: Fix SCI on IOAPIC != 0
  x86, ia32_aout: do not kill argument mapping
  x86, irq: Move __setup_vector_irq() before the first irq enable in cpu online path
  x86, irq: Update the vector domain for legacy irqs handled by io-apic
  x86, irq: Don't block IRQ0_VECTOR..IRQ15_VECTOR's on all cpu's
