The UV BIOS has been updated to implement some of our interface
functionality differently than originally expected. These patches update
the kernel to the bios implementation and include a few minor bug fixes
which prevent us from doing significant testing on real hardware.

This patch:

For SGI UV systems, translate from a global physical address back to a
socket physical address. This does nothing to ensure the socket physical
address is actually addressable by the kernel. That is the responsibility
of the user of the function.
