Pull irq fixes from Ingo Molnar:
"Mostly irqchip driver fixes, plus a symbol export"
* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
kernel/irq: Export irq_set_parent()
irqchip/gic: Add missing \n to CPU IF adjustment message
irqchip/jcore: Don't show Kconfig menu item for driver
irqchip/eznps: Drop pointless static qualifier in nps400_of_init()
irqchip/gic-v3-its: Fix entry size mask for GITS_BASER
irqchip/gic-v3-its: Fix 64bit GIC{R,ITS}_TYPER accesses
