I'm not keen on splitting up printk strings. It makes it more difficult
to grep for them. It's nice and easy if you can just copy most of the
log message into grep and get to the correct bit of code.

There has already been a patch for this -- I don't know if it's stuck in
Greg's queue or it got lost, but that mailing list is now dead so we can
just drop the second half of that message.
