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]
