Huh?  Who cares where it's mapped.  "Some unused space."
A pointer is a pointer.

In my case there is a direct correlation between the "base address"
and the "ioremaped address" -- the addition of a constant.  That's
the win for using 64-bit pointers.  ;-)

The only machines I knew about that had this were the DEC NUMA
machines.  What does your bus configuration look like?
