Yeah. It's after doing

	git clean -dqfx
	make oldconfig

where I tend to use "git clean -dqfx" instead of "make mrproper" these 
days. 

Note that my "oldconfig" really only does the things I need, so this is 
_not_ a "allmodconfig" or anything like that. That would take much longer. 
It only has the drivers I use, and the stuff I actually need (it's not a 
embedded kernel in any way, but it's definitely pared down config exactly 
because I like being able to rebuild my kernels without wasting time on 
thousands of drivers that I can't use anyway).

Other people can do the "does it compile?" testing. Not worth my time, I 
feel ;)

Well, the difference really is the beefy box. And the fact that I hate 
modules, and I hate building stuff that I don't actually need. 

I literally turn off CONFIG_MODULES entirely.
