Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq fixes from Thomas Gleixner: "This contains: - a series of fixes for interrupt drivers to prevent a potential race when installing a chained interrupt handler - a fix for cpumask pointer misuse - a fix for using the wrong interrupt number from struct irq_data - removal of unused code and outdated comments - a few new helper functions which allow us to cleanup the interrupt handling code further in 4.3 I decided against doing the cleanup at the end of this merge window and rather do the preparatory steps for 4.3, so we can run the final ABI change at the end of the 4.3 merge window with less risk" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (26 commits) ARM/LPC32xx: Use irq not hwirq for __irq_set_handler_locked() genirq: Implement irq_set_handler_locked()/irq_set_chip_handler_name_locked() genirq: Introduce helper irq_desc_get_irq() genirq: Remove irq_node() genirq: Clean up outdated comments related to include/linux/irqdesc.h mn10300: Fix incorrect use of irq_data->affinity MIPS/ralink: Fix race in installing chained IRQ handler MIPS/pci: Fix race in installing chained IRQ handler MIPS/ath25: Fix race in installing chained IRQ handler MIPS/ath25: Fix race in installing chained IRQ handler m68k/psc: Fix race in installing chained IRQ handler avr32/at32ap: Fix race in installing chained IRQ handler sh/intc: Fix race in installing chained IRQ handler sh/intc: Fix potential race in installing chained IRQ handler pinctrl/sun4i: Fix race in installing chained IRQ handler pinctrl/samsung: Fix race in installing chained IRQ handler pinctrl/samsung: Fix race in installing chained IRQ handler pinctrl/exynos: Fix race in installing chained IRQ handler pinctrl/st: Fix race in installing chained IRQ handler pinctrl/adi2: Fix race in installing chained IRQ handler ...
