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

* 'irq-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (76 commits)
  x86, apic: Fix dummy apic read operation together with broken MP handling
  x86, apic: Restore irqs on fail paths
  x86: Print real IOAPIC version for x86-64
  x86: enable_update_mptable should be a macro
  sparseirq: Allow early irq_desc allocation
  x86, io-apic: Don't mark pin_programmed early
  x86, irq: don't call mp_config_acpi_gsi() if update_mptable is not enabled
  x86, irq: update_mptable needs pci_routeirq
  x86: don't call read_apic_id if !cpu_has_apic
  x86, apic: introduce io_apic_irq_attr
  x86/pci: add 4 more return parameters to IO_APIC_get_PCI_irq_vector(), fix
  x86: read apic ID in the !acpi_lapic case
  x86: apic: Fixmap apic address even if apic disabled
  x86: display extended apic registers with print_local_APIC and cpu_debug code
  x86: read apic ID in the !acpi_lapic case
  x86: clean up and fix setup_clear/force_cpu_cap handling
  x86: apic: Check rev 3 fadt correctly for physical_apic bit
  x86/pci: update pirq_enable_irq() to setup io apic routing
  x86/acpi: move setup io apic routing out of CONFIG_ACPI scope
  x86/pci: add 4 more return parameters to IO_APIC_get_PCI_irq_vector()
