It uses it to filter out interrupts, as well as to print the:

"<=========="

"==========>"

annotations. Since function tracing only traces C functions, this will
be lost.

That said, we could possibly replace that check with keeping track
of the hardirq state in the "flags" field of the trace event entry.
