Do you even need these? Can they be changed by ftrace?
And see the previous email about not touching the original location at all, adn just duplicating that entry, avoiding all the need for shuffling. I *really* hope that ftrace doesn't depend on changing the return %eip on the stack. That would be truly nasty.
