Yup, that part of the patch looks wrong.
However, a mechanical replacement of unsigned long's with
resource_size_t to hold physical addresses should be fine despite the
lack of feedback from LSI.
Pravin, that ioremap definitely seems like it has nothing to do there,
port IO is already remapped for you by the core PCI code and should work
"as is". Please respin without that change.
