Subject: [PATCH v2 0/2] tracing: Make synthetic events a separate option

Hi Steve,

These are the same patches as v1, but after posting v1 I realized that
if you applied them on top of the other patchset I posted awhile back
("[PATCH 0/3] tracing: histogram internals doc, hist_debug, and misc")
[1], you wouldn't be able to apply these.

So assuming you apply the other patchset first, these should apply
cleanly on top of those.

Thanks,

Tom

v1 text:

Since synthetic events can now be used separately from hist triggers,
it makes sense to actually separate them into different options.  It
also makes sense in terms of file bloat - trace_events_hist.c was
getting very large and this makes it smaller and easier to follow.

Thanks,

Tom
