So I tested using real x86 livepatches, and it worked as expected. The test was
done by taking the livepatches, removing all externalized variables (those that
we need to call kallsyms_lookup), and compiling as usual and using
klp-convert to create the necessary relocation entries.

I'll keep testing with more livepatches for now on, and let you know if I find
any issue.
