Merge branch irq/riscv-ipi into irq/irqchip-next
* irq/riscv-ipi: : . : RISC-V IPI rework from Anup Patel: : : "This series aims to improve IPI support in Linux RISC-V in following ways: : 1) Treat IPIs as normal per-CPU interrupts instead of having custom RISC-V : specific hooks. This also makes Linux RISC-V IPI support aligned with : other architectures. : 2) Remote TLB flushes and icache flushes should prefer local IPIs instead : of SBI calls whenever we have specialized hardware (such as RISC-V AIA : IMSIC and RISC-V SWI) which allows S-mode software to directly inject : IPIs without any assistance from M-mode runtime firmware." : . irqchip/riscv-intc: Add empty irq_eoi() for chained irq handlers RISC-V: Use IPIs for remote icache flush when possible RISC-V: Use IPIs for remote TLB flush when possible RISC-V: Allow marking IPIs as suitable for remote FENCEs RISC-V: Treat IPIs as normal Linux IRQs irqchip/riscv-intc: Allow drivers to directly discover INTC hwnode RISC-V: Clear SIP bit only when using SBI IPI operations Signed-off-by: Marc Zyngier <maz@kernel.org>
