Merge tag 'irq-core-2021-10-31' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "Updates for the interrupt subsystem: Core changes: - Prevent a potential deadlock when initial priority is assigned to a newly created interrupt thread. A recent change to plug a race between cpuset and __sched_setscheduler() introduced a new lock dependency which is now triggered. Break the lock dependency chain by moving the priority assignment to the thread function. - A couple of small updates to make the irq core RT safe. - Confine the irq_cpu_online/offline() API to the only left unfixable user Cavium Octeon so that it does not grow new usage. - A small documentation update Driver changes: - A large cross architecture rework to move irq_enter/exit() into the architecture code to make addressing the NOHZ_FULL/RCU issues simpler. - The obligatory new irq chip driver for Microchip EIC - Modularize a few irq chip drivers - Expand usage of devm_*() helpers throughout the driver code - The usual small fixes and improvements all over the place" * tag 'irq-core-2021-10-31' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (53 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() ...
