Thanks for testing. Yes, Josh and I have been discussing the orc_unwind
issues. I've root caused one issue already, in that objtool places an
orc_unwind_ip address just outside the section, so my algorithm fails
to relocate this address. There are other issues as well that I still
haven't root caused. I'll be addressing this in v5 and plan to have
something that passes livepatch testing with that version.

FWIW, I'm okay with seeing fgkaslr be developed progressively. Getting
it working with !livepatching would be fine as a first step. There's
value in getting the general behavior landed, and then continuing to
improve it.
