When more than one header is included under CREATE_TRACE_POINTS the DECLARE_TRACE() macro is not defined back to its original meaning and the second include will fail to initialize the TRACE_EVENT() and DECLARE_TRACE() correctly. To fix this the tracepoint.h file moves the define of DECLARE_TRACE() out of the #ifdef _LINUX_TRACEPOINT_H protection (just like the define of the TRACE_EVENT()). This way the define_trace.h will undef the DECLARE_TRACE() at the end and allow new headers to start from scratch. This patch also requires fixing the include/events/napi.h It currently uses DECLARE_TRACE() and should be converted to a TRACE_EVENT() format. But I'll leave that change to the authors of that file. But since the napi.h file depends on using the CREATE_TRACE_POINTS and does not define its own DEFINE_TRACE() it must use the define_trace.h method instead.
