tracing: Make graph related irqs/preemptsoff functions global
Move trace_graph_function() and print_graph_headers_flags() functions to the trace_function_graph.c to be globaly available. Signed-off-by: Jiri Olsa <jolsa@redhat.com> LKML-Reference: <1285243253-7372-3-git-send-email-jolsa@redhat.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
