That's right, but since actual fixes anyway require changes to kexec core,
I think it's better to refactor first. The core than will take care of
proper freeing in the most cases.

And since CMA support in kexec is quite new I think the entire set can be
backported to stable then.

I'm planning to have a closer look at the refactoring Really Soon :)
