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.
