I'm adding SystemTap support for the format strings in the TRACE_EVENT
macros.  The softirq's TP_fast_assign uses softirq_to_name, and so that
array is needed to prepare the softirq's trace string.

So, there's no explicit reference to the symbol in SystemTap -- it's
just indirectly referenced by the tracepoint declaration.

Thanks,

Josh
