Merge branch 'irq-cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip
* 'irq-cleanup-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: (23 commits) genirq: Expand generic show_interrupts() gpio: Fold irq_set_chip/irq_set_handler to irq_set_chip_and_handler gpio: Cleanup genirq namespace arm: ep93xx: Add basic interrupt info arm/gpio: Remove three copies of broken and racy debug code xtensa: Use generic show_interrupts() xtensa: Convert genirq namespace xtensa: Use generic IRQ Kconfig and set GENERIC_HARDIRQS_NO_DEPRECATED xtensa: Convert s6000 gpio irq_chip to new functions xtensa: Convert main irq_chip to new functions um: Use generic show_interrupts() um: Convert genirq namespace m32r: Use generic show_interrupts() m32r: Convert genirq namespace h8300: Use generic show_interrupts() h8300: Convert genirq namespace avr32: Cleanup eic_set_irq_type() avr32: Use generic show_interrupts() avr: Cleanup genirq namespace avr32: Use generic IRQ config, enable GENERIC_HARDIRQS_NO_DEPRECATED ... Fix up trivial conflict in drivers/gpio/timbgpio.c
