Merge tag 'irqchip-core-3.18' of git://git.infradead.org/users/jcooper/linux into irq/core
irqchip core changes for v3.18
- renesas: suspend to RAM, runtime PM, cleanups and DT binding docs
- keystone: add new driver
- hip04: add Hisilicon HiP04 driver (without touching irq-gic.c)
- gic: Use defines instead of magic number, preserve v2 bybass bits
- handle_domain_irq: common low level interrupt entry handler
