Thanks will update the patch. As you noticied the patch series was not
tested on anything other than power7 and power8 (BE/LE). So any testing
on other platforms is going to be really useful. Now I did compile test
this with large number of configs. I guess none of them enable
STRICT_MM_TYPES.

Did the series boot fine on the platform after the above fix ?
