This patch set is about fine grained tuning of what tracepoints get
enabled and which don't. I honestly think that this should only be
permitted if CONFIG_EMBEDDED is set (if it should be permitted at all).
I would much rather find a way to lower the tracepoint footprint than to
pick and choose what tracepoints get enabled.
