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() ...
