The proper way to fix this is to include either

	linux/io-64-nonatomic-hi-lo.h

or

	linux/io-64-nonatomic-lo-hi.h

whichever is appropriate.

Hmmmm, is that not what I did?

Although I did not know about io-64-nonatomic-hi-lo.h. What is the
difference and which one is needed here?

There is apparently another failure when OF_MDIO is not set, I guess I
can try to look into that as well and respin into a series if
necessary.

Cheers,
Nathan
