Sorry, I did not have a clean base and the Kconfig had another change.

Here is a tree with the changes applied:

That's because I don't know if the later patches will be accepted. By
queueing this patch first it can be applied standalone to ppc tree
without regard for the other patches. It's a copy of the s390 code so it
needs the same rework - not really adding complexity.
