Thanks for this work!

I would like to add to the motivation here:

It is actually useful to livepatch OOT modules in production.
When using kpatch-build, we (Meta) generally do not patch OOT
modules. But there was one case where we had to do it, and it
required quite some manual work.

If we can make building livepatch for OOT easy, we are likely to
use it regularly in the future.

Thanks,
Song
