	In general it's preferable to avoid placing cpumasks on the stack, as for large values of NR_CPUS these can consume significant amounts of stack space and make stack overflows more likely. Use cpumask_first_and_and() to avoid the need for a temporary cpumask on the stack.

2024-03-25	irqchip: Add RISC-V advanced PLIC driver for direct-mode	Anup Patel
	The RISC-V advanced interrupt architecture (AIA) specification defines advanced platform-level interrupt controller (APLIC) which has two modes of operation: 1) Direct mode and 2) MSI mode. (For more details, refer https://github.com/riscv/riscv-aia) In APLIC direct-mode, wired interrupts are forwared to CPUs (or HARTs) as a local external interrupt. Add a platform irqchip driver for the RISC-V APLIC direct-mode to support RISC-V platforms having only wired interrupts.
