It looks like your corner case arch and config was never covered by the kbuild robot which has run extensively on this patchset. Anyway, I think the fix is to put back the ioread64/write64 prototypes (even though they are only used in this one corner). Can you try it with the following patch to ensure it fixes things for you?
