Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "This updated pull request does not contain the last few GIC related patches which were reported to cause a regression. There is a fix available, but I let it breed for a couple of days first. The irq departement provides: - new infrastructure to support non PCI based MSI interrupts - a couple of new irq chip drivers - the usual pile of fixlets and updates to irq chip drivers - preparatory changes for removal of the irq argument from interrupt flow handlers - preparatory changes to remove IRQF_VALID" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (129 commits) irqchip/imx-gpcv2: IMX GPCv2 driver for wakeup sources irqchip: Add bcm2836 interrupt controller for Raspberry Pi 2 irqchip: Add documentation for the bcm2836 interrupt controller irqchip/bcm2835: Add support for being used as a second level controller irqchip/bcm2835: Refactor handle_IRQ() calls out of MAKE_HWIRQ PCI: xilinx: Fix typo in function name irqchip/gic: Ensure gic_cpu_if_up/down() programs correct GIC instance irqchip/gic: Only allow the primary GIC to set the CPU map PCI/MSI: pci-xgene-msi: Consolidate chained IRQ handler install/remove unicore32/irq: Prepare puv3_gpio_handler for irq argument removal tile/pci_gx: Prepare trio_handle_level_irq for irq argument removal m68k/irq: Prepare irq handlers for irq argument removal C6X/megamode-pic: Prepare megamod_irq_cascade for irq argument removal blackfin: Prepare irq handlers for irq argument removal arc/irq: Prepare idu_cascade_isr for irq argument removal sparc/irq: Use access helper irq_data_get_affinity_mask() sparc/irq: Use helper irq_data_get_irq_handler_data() parisc/irq: Use access helper irq_data_get_affinity_mask() mn10300/irq: Use access helper irq_data_get_affinity_mask() irqchip/i8259: Prepare i8259_irq_dispatch for irq argument removal ...
