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"
