Merge tag 'irq-core-2022-08-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "Updates for interrupt core and drivers: Core: - Fix a few inconsistencies between UP and SMP vs interrupt affinities - Small updates and cleanups all over the place New drivers: - LoongArch interrupt controller - Renesas RZ/G2L interrupt controller Updates: - Hotpath optimization for SiFive PLIC - Workaround for broken PLIC edge triggered interrupts - Simall cleanups and improvements as usual" * tag 'irq-core-2022-08-01' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (52 commits) irqchip/mmp: Declare init functions in common header file irqchip/mips-gic: Check the return value of ioremap() in gic_of_init() genirq: Use for_each_action_of_desc in actions_show() irqchip / ACPI: Introduce ACPI_IRQ_MODEL_LPIC for LoongArch irqchip: Add LoongArch CPU interrupt controller support irqchip: Add Loongson Extended I/O interrupt controller support irqchip/loongson-liointc: Add ACPI init support irqchip/loongson-pch-msi: Add ACPI init support irqchip/loongson-pch-pic: Add ACPI init support irqchip: Add Loongson PCH LPC controller support LoongArch: Prepare to support multiple pch-pic and pch-msi irqdomain LoongArch: Use ACPI_GENERIC_GSI for gsi handling genirq/generic_chip: Export irq_unmap_generic_chip ACPI: irq: Allow acpi_gsi_to_irq() to have an arch-specific fallback APCI: irq: Add support for multiple GSI domains LoongArch: Provisionally add ACPICA data structures irqdomain: Use hwirq_max instead of revmap_size for NOMAP domains irqdomain: Report irq number for NOMAP domains irqchip/gic-v3: Fix comment typo dt-bindings: interrupt-controller: renesas,rzg2l-irqc: Document RZ/V2L SoC ...
