tracing: Add new trace_marker_raw
A new file is created: /sys/kernel/debug/tracing/trace_marker_raw This allows for appications to create data structures and write the binary data directly into it, and then read the trace data out from trace_pipe_raw into the same type of data structure. This saves on converting numbers into ASCII that would be required by trace_marker. Suggested-by: Olof Johansson <olof@lixom.net> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
