Here is the summary with links: - [v18,1/7] RISC-V: Clear SIP bit only when using SBI IPI operations https://git.kernel.org/riscv/c/3ee92565b83e - [v18,2/7] irqchip/riscv-intc: Allow drivers to directly discover INTC hwnode https://git.kernel.org/riscv/c/0c60a31ce62c - [v18,3/7] RISC-V: Treat IPIs as normal Linux IRQs https://git.kernel.org/riscv/c/832f15f42646 - [v18,4/7] RISC-V: Allow marking IPIs as suitable for remote FENCEs https://git.kernel.org/riscv/c/fb0f3d281b7f - [v18,5/7] RISC-V: Use IPIs for remote TLB flush when possible https://git.kernel.org/riscv/c/18d2199d8105 - [v18,6/7] RISC-V: Use IPIs for remote icache flush when possible https://git.kernel.org/riscv/c/627922843235 - [v18,7/7] irqchip/riscv-intc: Add empty irq_eoi() for chained irq handlers https://git.kernel.org/riscv/c/f8415f2def18
