- Allow the use of tracepoints as software performance events.

- When this is enabled, you can create perf events based on
- tracepoints using PERF_TYPE_TRACEPOINT and the tracepoint ID
- found in debugfs://tracing/events/*/*/id. (The -e/--events
- option to the perf tool can parse and interpret symbolic
- tracepoints, in the subsystem:tracepoint_name format.)
