Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull core irq updates from Thomas Gleixner: "Updates from the irq departement: - Update the interrupt spreading code so it handles numa node with different CPU counts properly. - A large overhaul of the ARM GiCv3 driver to support new PPI and SPI ranges. - Conversion of all alloc_fwnode() users to use physical addresses instead of virtual addresses so the virtual addresses are not leaked. The physical address is sufficient to identify the associated interrupt chip. - Add support for Marvel MMP3, Amlogic Meson SM1 interrupt chips. - Enforce interrupt threading at compile time if RT is enabled. - Small updates and improvements all over the place" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (37 commits) irqchip/gic-v3-its: Fix LPI release for Multi-MSI devices irqchip/uniphier-aidet: Use devm_platform_ioremap_resource() irqdomain: Add the missing assignment of domain->fwnode for named fwnode irqchip/mmp: Coexist with GIC root IRQ controller irqchip/mmp: Mask off interrupts from other cores irqchip/mmp: Add missing chained_irq_{enter,exit}() irqchip/mmp: Do not use of_address_to_resource() to get mux regs irqchip/meson-gpio: Add support for meson sm1 SoCs dt-bindings: interrupt-controller: New binding for the meson sm1 SoCs genirq/affinity: Remove const qualifier from node_to_cpumask argument genirq/affinity: Spread vectors on node according to nr_cpu ratio genirq/affinity: Improve __irq_build_affinity_masks() irqchip: Remove dev_err() usage after platform_get_irq() irqchip: Add include guard to irq-partition-percpu.h irqchip/mmp: Do not call irq_set_default_host() on DT platforms irqchip/gic-v3-its: Remove the redundant set_bit for lpi_map irqchip/gic-v3: Add quirks for HIP06/07 invalid GICD_TYPER erratum 161010803 irqchip/gic: Skip DT quirks when evaluating IIDR-based quirks irqchip/gic-v3: Warn about inconsistent implementations of extended ranges irqchip/gic-v3: Add EPPI range support ...
