Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "This is a rather large update post rc1 due to the final steps of cleanups and API changes which had to wait for the preparatory patches to hit your tree. - Regression fixes for ARM GIC irqchips - Regression fixes and lockdep anotations for renesas irq chips - The leftovers of the cleanup and preparatory patches which have been ignored by maintainers - Final conversions of the newly merged users of obsolete APIs - Final removal of obsolete APIs - Final removal of ARM artifacts which had been introduced during the conversion of ARM to the generic interrupt code. - Final split of the irq_data into chip specific and common data to reflect the needs of hierarchical irq domains. - Treewide removal of the first argument of interrupt flow handlers, i.e. the irq number, which is not used by the majority of handlers and simple to retrieve from the other argument the irq descriptor. - A few comment updates and build warning fixes" * 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (40 commits) arm64: Remove ununsed set_irq_flags ARM: Remove ununsed set_irq_flags sh: Kill off set_irq_flags usage irqchip: Kill off set_irq_flags usage gpu/drm: Kill off set_irq_flags usage genirq: Remove irq argument from irq flow handlers genirq: Move field 'msi_desc' from irq_data into irq_common_data genirq: Move field 'affinity' from irq_data into irq_common_data genirq: Move field 'handler_data' from irq_data into irq_common_data genirq: Move field 'node' from irq_data into irq_common_data irqchip/gic-v3: Use IRQD_FORWARDED_TO_VCPU flag irqchip/gic: Use IRQD_FORWARDED_TO_VCPU flag genirq: Provide IRQD_FORWARDED_TO_VCPU status flag genirq: Simplify irq_data_to_desc() genirq: Remove __irq_set_handler_locked() pinctrl/pistachio: Use irq_set_handler_locked gpio: vf610: Use irq_set_handler_locked powerpc/mpc8xx: Use irq_set_handler_locked() powerpc/ipic: Use irq_set_handler_locked() powerpc/cpm2: Use irq_set_handler_locked() ...
