Subject: [PATCH] degrade severity of lockdep printk

From: Kyle McMartin <kyle@...hat.com>

While it means something is awry, the BUG prefix confuses users and
possibly the kerneloops tool. It's also being trivially exhausted in
normal use on my laptop and several other folks machines, but that will
need another look.
