In my k3s-wip branch, I have a series of kernel configs directly related
and named for kubernetes .. I had hoped to just merge this into that
effort, but as you can see from my posts, getting k3s done is taking
longer than I wanted.

So I've gone ahead and merged this, and I'll consolidate them later when
I finish k3s.
