Well, the limitations of the current code have been exposed while trying
to fix kexec. So I would say this is the best place to fix those
limitations.

If you're intending these patches to the backported into stable release
then you could first fix the issues and later patches *in the same
series* can do the refactor. That way, the patches that have the actual
fix can be backported and we can avoid backporting the refactor.
