    Is the idea here to mitigate the amount of driver code changes, or
    something else?

    If you are sticking a cookie in there behind the scenes, why go ahead
    and use ioremap?

    We -already- have a system which does remapping and returns cookies and
    such for PCI mem regions. Why not use it for I/O regions too?
