> irq: Add tracepoint to softirq_raise
>
> Add a tracepoint for tracing when softirq action is raised.
>
> This and the existing tracepoints complete softirq's tracepoints:
> softirq_raise, softirq_entry and softirq_exit.
>
> And when this tracepoint is used in combination with
> the softirq_entry tracepoint we can determine
> the softirq raise latency.
