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
