Please don't do any pathname changes. Even if ppc64 isn't correct it's
what applications expect and what we should provide for a coherent user
interface.

This should be the only change you need, and it should follow kernel
coding style, aka:
if (!machine_is(pseries) && !machine_is(chrp))
return -ENODEV;

And given this check I wonder why we need the platform check at all. It
should be safe to just remove it.
