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

Pull irq updates from Thomas Gleixner:
 "The irq department provides:

   - a major update to the auto affinity management code, which is used
     by multi-queue devices

   - move of the microblaze irq chip driver into the common driver code
     so it can be shared between microblaze, powerpc and MIPS

   - a series of updates to the ARM GICV3 interrupt controller

   - the usual pile of fixes and small improvements all over the place"
