[PATCH 2/9] tracing/softirq: Move __raise_softirq_irqoff() out of header

[Steven Rostedt]

From: Steven Rostedt <srostedt@xxxxxxxxxx>

The __raise_softirq_irqoff() contains a tracepoint. As tracepoints in headers
can cause issues, and not to mention, bloats the kernel when they are
in a static inline, it is best to move the function that contains the
tracepoint out of the header and into softirq.c.
