From: Arnd Bergmann <arnd@arndb.de>

Most of the patches I sent so far for the -Wmissing-prototype warnings
have made it into linux-next now. There are a few that I'm resending
now as nobody has picked them up, and then a number of fixes that I
found while test-building across all architectures rather than just the
ones I usually test.

The first 15 patches in this series should be uncontroversial, so
I expect that either a subsystem maintainer or Andrew Morton can
apply these directly.

For the last two patches, these might still need some debate about how
to handle them. I added a Kconfig option to turn off most of the missing
prototype warnings in the architectures that nobody has fixed yet,
see patch 16 for those. The last patch does cause some known warnings
and likely unknown ones for architectures other than x86 and arm,
so applying it now will bring new problems, but not applying it also
means that new warnings creep in, so I think this is mainly a question
of what the best timing is for having this in linux-next.
