It's ok for me to revert, but if it's reverted should consider
the warning only patch version instead.

https://git.kernel.org/pub/scm/linux/kernel/git/ak/linux-misc.git/commit/?h=spec/retpoline-module-2&id=b40b7c1dbffaa636906b774ef5519882060e1aa0

I had posted that earlier, but reviewers in the end preferred
the simple modversions variant.

I think we should have something at least for 4.15 to catch mistakes.
