Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip into next
Pull core irq updates from Thomas Gleixner: "The irq department delivers: - Another tree wide update to get rid of the horrible create_irq interface along with its even more horrible variants. That also gets rid of the last leftovers of the initial sparse irq hackery. arch/driver specific changes have been either acked or ignored. - A fix for the spurious interrupt detection logic with threaded interrupts. - A new ARM SoC interrupt controller - The usual pile of fixes and improvements all over the place" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits) Documentation: brcmstb-l2: Add Broadcom STB Level-2 interrupt controller binding irqchip: brcmstb-l2: Add Broadcom Set Top Box Level-2 interrupt controller genirq: Improve documentation to match current implementation ARM: iop13xx: fix msi support with sparse IRQ genirq: Provide !SMP stub for irq_set_affinity_notifier() irqchip: armada-370-xp: Move the devicetree binding documentation irqchip: gic: Use mask field in GICC_IAR genirq: Remove dynamic_irq mess ia64: Use irq_init_desc genirq: Replace dynamic_irq_init/cleanup genirq: Remove irq_reserve_irq[s] genirq: Replace reserve_irqs in core code s390: Avoid call to irq_reserve_irqs() s390: Remove pointless arch_show_interrupts() s390: pci: Check return value of alloc_irq_desc() proper sh: intc: Remove pointless irq_reserve_irqs() invocation x86, irq: Remove pointless irq_reserve_irqs() call genirq: Make create/destroy_irq() ia64 private tile: Use SPARSE_IRQ tile: pci: Use irq_alloc/free_hwirq() ...
