Marc Zyngier e7b5771aa0 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
