tracing: Add DEFINE_EVENT(), DEFINE_SINGLE_EVENT() support to docbook
The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook style comments that used to live with 'TRACE_EVENT()' are now moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook system understand the new 'DEFINE_EVENT()' macro. In addition I've tried to futureproof the patch, by also adding support for 'DEFINE_SINGLE_EVENT()', since there has been discussion about renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT(). Without this patch the tracepoint docbook fails to build. I've verified that this patch correctly builds the tracepoint docbook which currently covers signals, and irqs. Changes in v2: - properly indent perl 'if' statements Signed-off-by: Jason Baron <jbaron@redhat.com> Acked-by: Steven Rostedt <rostedt@goodmis.org> Acked-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: William Cohen <wcohen@redhat.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca> Cc: Masami Hiramatsu <mhiramat@redhat.com> LKML-Reference: <200912011718.nB1HIn7t011371@int-mx04.intmail.prod.int.phx2.redhat.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
