I'm a little concerned here. This sounds like forced unification. If we can't clean up the infrastructure so things are obviously better and cleanly factored for both architectures we should not unify the files. As a general principle I would rather have two crudy files side by side the one super crudy file. So for unification I suggest finally fixing this right and taking the apics completely out of the kexec on panic path.
