Merge tag 'irqchip-5.16' into irq/core
Merge irqchip updates for Linux 5.16 from Marc Zyngier: - A large cross-arch rework to move irq_enter()/irq_exit() into the arch code, and removing it from the generic irq code. Thanks to Mark Rutland for the huge effort! - A few irqchip drivers are made modular (broadcom, meson), because that's apparently a thing... - A new driver for the Microchip External Interrupt Controller - The irq_cpu_offline()/irq_cpu_online() API is now deprecated and can only be selected on the Cavium Octeon platform. Once this platform is removed, the API will be removed at the same time. - A sprinkle of devm_* helper, as people seem to love that. - The usual spattering of small fixes and minor improvements. * tag 'irqchip-5.16': (912 commits) h8300: Fix linux/irqchip.h include mess dt-bindings: irqchip: renesas-irqc: Document r8a774e1 bindings MIPS: irq: Avoid an unused-variable error genirq: Hide irq_cpu_{on,off}line() behind a deprecated option irqchip/mips-gic: Get rid of the reliance on irq_cpu_online() MIPS: loongson64: Drop call to irq_cpu_offline() irq: remove handle_domain_{irq,nmi}() irq: remove CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY irq: riscv: perform irqentry in entry code irq: openrisc: perform irqentry in entry code irq: csky: perform irqentry in entry code irq: arm64: perform irqentry in entry code irq: arm: perform irqentry in entry code irq: add a (temporary) CONFIG_HANDLE_DOMAIN_IRQ_IRQENTRY irq: nds32: avoid CONFIG_HANDLE_DOMAIN_IRQ irq: arc: avoid CONFIG_HANDLE_DOMAIN_IRQ irq: add generic_handle_arch_irq() irq: unexport handle_irq_desc() irq: simplify handle_domain_{irq,nmi}() irq: mips: simplify do_domain_IRQ() ...
