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

Pull irq fixes from Thomas Gleixner:
 "Three fixes for irq core and irq chip drivers:

   - Do not set the irq type if type is NONE.  Fixes a boot regression
     on various SoCs

   - Use the proper cpu for setting up the GIC target list.  Discovered
     by the cpumask debugging code.

   - A rather large fix for the MIPS-GIC so per cpu local interrupts
     work again.  This was discovered late because the code falls back
     to slower timers which use normal device interrupts"

* 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  irqchip/mips-gic: Fix local interrupts
  irqchip/gicv3: Silence noisy DEBUG_PER_CPU_MAPS warning
  genirq: Skip chained interrupt trigger setup if type is IRQ_TYPE_NONE
