Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull timer fixlets from Thomas Gleixner:
"Two trivial fixes which add missing header fileas and forward
declarations so the code will compile even when the magic include
chains are different"

irqchip/gic-v3: Add missing include for barrier.h
irqchip/gic-v3: Add missing struct device_node declaration
