The machine address we're trying to map is 0x42c000000. That is above
16GB, because the machine has 16GB of RAM plus a 2GB IO hole, meaning
addresses up to 18GB are actually possible.
However, the flag we use to indicate a foreign mapping is the 16GB bit,
0x400000000. (We unfortunately did not start with bits at the top of the
Aside from having Xen pick another bit, we will need a Linux patch
