We may as well just add a prebuild step that runs the entire kernel
through a sed script that changes everything to atomic, then we can
continue writing normal code.

Can we do a smaller diff without all the atomic fluff?

I can agree there's value in moving this stuff out of kernel lock, but
I don't think this amount of churn is productive.
