void arch_cpu_kick ( struct cpu * cpu )

Makes another CPU enter the kernel now, with an inter-processor interrupt: to run a thread that just became ready if it's idle, or so that its thread sees it was killed or takes its signals.

Each architecture implements it; with one CPU, it does nothing.

Parameters

cpu the CPU
