I'm conflicted by this change.
You've clearly changed your mind since you rejected my patch introducing
this infrastructure and starting to use it.
Given that it is a reoccurring bug with livepatching which has been in
need of fixing since 2018, I'd organised some work to port Linux's
linkage.h as something more likely to have been acceptable.
