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"
