Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next
Pull core irq updates from Thomas Gleixner:
"The irq department delivers:
- Another tree wide update to get rid of the horrible create_irq
interface along with its even more horrible variants. That also
gets rid of the last leftovers of the initial sparse irq hackery.
arch/driver specific changes have been either acked or ignored.
- A fix for the spurious interrupt detection logic with threaded
interrupts.
- A new ARM SoC interrupt controller
- The usual pile of fixes and improvements all over the place"
