And you do (after seeing dates of the posts there), sorry for the noise.
Jessica, I think I am perfectly fine with introducing some arch-specific
code because of this problem.
We used generic apply_relocate_add() because it was a single
arch-independent entry point. There is no such things for paravirt_ops,
alternatives, jump labels and such things. In fact only module_finalize()
is there and that is not enough. So some arch-specific code in livepatch
seems to be unnecessary.
Cheers,
Miroslav
