There is currently no 64-bit machine that is supported by current kernels,
and I don't think there is any reason to add this again.

I'm not sure what the point of your plan to replace CONFIG_POWER4 is, but
it sounds like this case is slightly different, as you remove a potential
feature, so I guess it should be a separate patch.
