Subject: [PATCH 0/7] Put "Kernel hacking" Kconfig menu on a diet

Michal, I figure you're the most logical person for these to go
through.

There is a fair amount of churn in the areas around these patches
so I've resolved conflicts a couple of times.  For the patches that
are almost purely code move patches, I'm doing this:

	cat foo.patch | grep '^[-+]' | perl -pe 's/^.//' | sort | uniq -c | sort -n

and watching for any non-even numbers coming out of uniq.  This
helps me make sure I'm not adding/removing code that I should not
be.

The Signed-off-by's in here look funky.  I changed employers
while working on this set, so I have signoffs from both email
addresses.

I think the "Kernel Hacking" menu has gotten a bit out of hand.  It
is over 120 lines long on my system with everything enabled and
options are scattered around it haphazardly.

Let's try to introduce some sanity.  This set takes that 120 lines
down to 55 and makes it vastly easier to find some things.  It's a
start.

This set stands on its own, but there is plenty of room for follow-up
patches.  The arch-specific debug options still end up getting stuck
in the top-level "kernel hacking" menu.  OPTIMIZE_INLINING, for
instance, could obviously go in to the "compiler options" menu, but
the fact that it is defined in arch/ in a separate Kconfig file keeps
it on its own for the moment.
