/*
* Stage 1 of the trace events.
*
* Override the macros in <trace/trace_event_types.h> to include the following:
*
* struct ftrace_raw_<call> {
* struct trace_entry ent;
* <type> <item>;
* [...]
* };
*
* The <type> <item> is created by the TRACE_FIELD(type, item, assign)
* macro. We simply do "type item;", and that will create the fields
* in the structure.
