[PATCH 7/7] sched: export the newly added tracepoints

[Qais Yousef <qais.yousef@arm.com>]

So that external modules can hook into them and extract the info they
need. Since these new tracepoints have no events associated with them
exporting these tracepoints make them useful for external modules to
perform testing and debugging. There's no other way otherwise to access
them.
