Sorry I missed v1, so I'm going to ask for more changes :}

Putting it here exposes it to the whole kernel, but it's only needed inside arch/powerpc/platforms/powermac.
The right place for the prototype is arch/powerpc/platforms/powermac/pmac.h, which is for platform internal prototypes.

The ifdef around the prototype doesn't gain much, and is extra visual noise, so I'd rather without it.
