ppc64 really needs ioaddr_t to be 64-bit, since I/O addresses really
are MMIO addresses, and remapped to a high range.

While the type is exported to userspace, there hasn't been any platforms
with PCMCIA on 64-bit powerpc until now, so changing it won't regress
any existing users.
In fact the only use of the type should be in the obsolete ioctl-based user
interface.  So instead of changing the size of the type you should

 a) make sure you're not using cardmgr
 b) fix up those places that still use ioaddr_t where they shouldn't
    and switch the to kio_addr_t (why not just unsigned long like all
    other busses?) 
I just noticed that feature-removal-schedule.txt says November 2005 for
the removal of the pcmcia ioctl's, but they're still there. I'm missing
the history here, any reason they weren't removed yet?
