Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull IRQ fixes from Ingo Molnar: "Mostly irqchip driver fixes, but also an irq core crash fix and a build fix" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: irqchip/mxs: Add missing set_handle_irq() irqchip/atmel-aic: Fix wrong bit operation for IRQ priority irqchip/gic-v3-its: Recompute the number of pages on page size change base: Export platform_msi_domain_[alloc,free]_irqs of: MSI: Simplify irqdomain lookup irqdomain: Allow domain lookup with DOMAIN_BUS_WIRED token irqchip: Fix dependencies for archs w/o HAS_IOMEM irqchip/s3c24xx: Mark init_eint as __maybe_unused genirq: Validate action before dereferencing it in handle_irq_event_percpu()
