Hmmm.  If we need to do this then maybe we should just get rid of the
arch/ppc versions of the relevant files and make ARCH=ppc use the
versions from arch/powerpc.

What do people think?  Do we make ARCH=ppc use more and more stuff
from arch/powerpc, and delete the duplicates from arch/ppc, or do
people want to be conservative and keep arch/ppc largely unchanged?
(I would prefer the former, myself.)

Paul.
