Anup Patel 5cf998ba8c RISC-V: self-contained IPI handling routine ... Currently, the IPI handling routine riscv_software_interrupt() does not take any argument and also does not perform irq_enter()/irq_exit(). This patch makes IPI handling routine more self-contained by: 1. Passing "pt_regs *" argument 2. Explicitly doing irq_enter()/irq_exit() 3. Explicitly save/restore "pt_regs *" using set_irq_regs() With above changes, IPI handling routine does not depend on caller function to perform irq_enter()/irq_exit() and save/restore of "pt_regs *" hence its more self-contained. This also enables us to call IPI handling routine from IRQCHIP drivers.
