Yes, but they generate warnings from sparse, and there
are currently quite a lot of them.
Maybe the patch should move the init functions into their
respective header files, i'll look at sortig that out and
re-issuing them.

I missed the actual definition, but, you notice it is
wrappered in `CONFIG_X86`, which isn't much used on non X86
systems.
