Put "Kernel hacking" Kconfig menu on a diet

Linus, I've tried to send these along to a couple of different maintainers for a couple of merge windows, but so far nobody has bitten.

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.

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. Here's the original posting:
