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: (32 commits) x86: disable __do_IRQ support sparseirq, powerpc/cell: fix unused variable warning in interrupt.c genirq: deprecate obsolete typedefs and defines genirq: deprecate __do_IRQ genirq: add doc to struct irqaction genirq: use kzalloc instead of explicit zero initialization genirq: make irqreturn_t an enum genirq: remove redundant if condition genirq: remove unused hw_irq_controller typedef irq: export remove_irq() and setup_irq() symbols irq: match remove_irq() args with setup_irq() irq: add remove_irq() for freeing of setup_irq() irqs genirq: assert that irq handlers are indeed running in hardirq context irq: name 'p' variables a bit better irq: further clean up the free_irq() code flow irq: refactor and clean up the free_irq() code flow irq: clean up manage.c irq: use GFP_KERNEL for action allocation in request_irq() kernel/irq: fix sparse warning: make symbol static irq: optimize init_kstat_irqs/init_copy_kstat_irqs ...
