As Geert poined out, I'm not seeing anything particular problematic with the
architectures lacking CONFIG_PREEMPT at the moment. This seems to be more
something about organizing KConfig files.

I find it a bit unfair that maintainers of architectures that have huge companies
behind them use their manpower to urge less popular architectures for removal just
because they don't have 150 people working on the port so they can keep up with
design changes quickly.
