Well, it's new now :-) I never expected people to use more than one
TRACE_SYSTEM in a single file, so I never documented that it shouldn't
be done.

I'm more worried about people using the same TRACE_SYSTEM in different
files, which will probably break now too.

I should update the comments about that.

Hmm, I must have missed the iwlwifi part, as that should have not built
with an allmodconfig :-/

Right, I'll need to pull this in my tree, as I have a set of patches
dependent on this.
