From: Lai Jiangshan <laijs@cn.fujitsu.com>

This patch adds a tracepoint to raising of softirq.
This is useful if you want to detect which hard interrupt raise softirq
and lets you know a time between raising softirq and performing softirq.
Combinating with other tracepoint, it lets us know a process of packets
(See patch 0/5).

          <idle>-0     [001] 241229.957184: softirq_raise: vec=3 [action=NET_RX]
          <idle>-0     [000] 241229.993399: softirq_raise: vec=1 [action=TIMER]
          <idle>-0     [000] 241229.993400: softirq_raise: vec=9 [action=RCU]

This is a same below.
