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

Pull irq updates from Thomas Gleixner:
 "Nothing exciting from the irq side for this merge window:

   - a new driver for a Mediatek SoC

   - ACPI support for ARM GICV3

   - support for shared nested interrupts

   - the usual pile of fixes and updates all over te place"
