Subject: [PATCH] tracing: Set user_events to BROKEN

From: "Steven Rostedt (Google)" <rostedt@...dmis.org>

After being merged, user_events become more visible to a wider audience
that have concerns with the current API. It is too late to fix this for
this release, but instead of a full revert, just mark it as BROKEN (which
prevents it from being selected in make config). Then we can work finding
a better API. If that fails, then it will need to be completely reverted.
