OK, so I just gave this a try...

- It forces the generation of a kernel configuration, something that the
  docs build has never done until now.  What are our changes of
  eliminating that?

- It did a bunch of other building, starting with objtool - again, never
  needed for the docs build before.

In the end, it died with:

> BINDGEN rust/bindings/bindings_generated.rs
> Failed to run rustfmt: No such file or directory (os error 2) (non-fatal, continuing)

Perhaps this is because I ignored the warnings about my Rust toolchain
being too new? (Rust 1.65.0, bindgen 0.63.0).  I get that only one
version is really supported, but it would be nice to fail a bit more
gracefully if at all possible.

Anyway, I've unapplied these for now; thoughts on all this?

Thanks,
