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
