Merge branch 'gic/cleanup' into next/soc
Merge in the gic cleanup since it has a handful of annoying internal conflicts with soc development branches. All of them are delete/delete conflicts. * gic/cleanup: irqchip: vic: add include of linux/irq.h 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 Signed-off-by: Olof Johansson <olof@lixom.net> Conflicts: arch/arm/mach-shmobile/smp-emev2.c arch/arm/mach-shmobile/smp-r8a7779.c arch/arm/mach-shmobile/smp-sh73a0.c arch/arm/mach-socfpga/platsmp.c
