Merge branch 'x86-irq-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'x86-irq-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
x86, acpi/irq: Define gsi_end when X86_IO_APIC is undefined
x86, irq: Kill io_apic_renumber_irq
x86, acpi/irq: Handle isa irqs that are not identity mapped to gsi's.
x86, ioapic: Simplify probe_nr_irqs_gsi.
x86, ioapic: Optimize pin_2_irq
x86, ioapic: Move nr_ioapic_registers calculation to mp_register_ioapic.
x86, ioapic: In mpparse use mp_register_ioapic
x86, ioapic: Teach mp_register_ioapic to compute a global gsi_end
x86, ioapic: Fix the types of gsi values
x86, ioapic: Fix io_apic_redir_entries to return the number of entries.
x86, ioapic: Only export mp_find_ioapic and mp_find_ioapic_pin in io_apic.h
x86, acpi/irq: Generalize mp_config_acpi_legacy_irqs
x86, acpi/irq: Fix acpi_sci_ioapic_setup so it has both bus_irq and gsi
x86, acpi/irq: pci device dev->irq is an isa irq not a gsi
x86, acpi/irq: Teach acpi_get_override_irq to take a gsi not an isa_irq
x86, acpi/irq: Introduce apci_isa_irq_to_gsi
