There are 50+ cases of Kconfig options setting the DEBUG flag, so there
might be room for a series to remove some of those. (Note that Joe says
there are valid reasons to use a Kconfig option to set this flag, if I'm
not misunderstanding Joe.) For what it's worth, I've added the list of
these (for v3.14-rc5) below.
