Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (116 commits) x86: Enable forced interrupt threading support x86: Mark low level interrupts IRQF_NO_THREAD x86: Use generic show_interrupts x86: ioapic: Avoid redundant lookup of irq_cfg x86: ioapic: Use new move_irq functions x86: Use the proper accessors in fixup_irqs() x86: ioapic: Use irq_data->state x86: ioapic: Simplify irq chip and handler setup x86: Cleanup the genirq name space genirq: Add chip flag to force mask on suspend genirq: Add desc->irq_data accessor genirq: Add comments to Kconfig switches genirq: Fixup fasteoi handler for oneshot mode genirq: Provide forced interrupt threading sched: Switch wait_task_inactive to schedule_hrtimeout() genirq: Add IRQF_NO_THREAD genirq: Allow shared oneshot interrupts genirq: Prepare the handling of shared oneshot interrupts genirq: Make warning in handle_percpu_event useful x86: ioapic: Move trigger defines to io_apic.h ... Fix up trivial(?) conflicts in arch/x86/pci/xen.c due to genirq name space changes clashing with the Xen cleanups. The set_irq_msi() had moved to xen_bind_pirq_msi_to_irq().
