OK, this should go as a separate change.

They may not need it. The helpers I created were for the macros that are
created by all TRACE_EVENT() instances. If the uprobes and kprobes only
have a single instance, then they probably don't need the helpers. But
they still call the perf_trace_buf_submit(), which can can probably be
cleaned up.
