After considering Linus's recent feedback on kernel configuration
complexity, I'm reconsidering this approach. He recently emphasized:

        "The kernel config phase is probably one of the biggest pain points for
        random new people trying to build their own kernels, and we DO NOT ASK
        PEOPLE STUIPID THINGS." --Linus

I will respin a new version, dropping this patch from the series to keep Linus’
blood pressure in check.
