Merge branch 'gic' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64 into next/cleanup
* 'gic' of git://git.kernel.org/pub/scm/linux/kernel/git/cmarinas/linux-aarch64:
irqchip: gic: Perform the gic_secondary_init() call via CPU notifier
irqchip: gic: Call handle_bad_irq() directly
arm: Move chained_irq_(enter|exit) to a generic file
arm: Move the set_handle_irq and handle_arch_irq declarations to asm/irq.h
+ Linux 3.9-rc3
