Your complaint was specifically about me adding it to paging.h so I
could use IS_ENABLED() and not out-of-line a trivial function.

As for general availably, while I agree in general that we have far too
much stuff included by default (I have some plans for that), the
contents of kconfig.h is fairly small, and exactly the same category of
information as config.h

I am looking to push for the use of IS_ENABLED() in preference to #ifdef
where possible, to reduce code-rot.
