Subject: [PATCH 0/2] xen-paciback: Fixes for PCI passthrough of AMD GPU.

I've got this patch series from Dwayne Litzenberger, as a fix for AMD GPU
passthrough. I don't have this hardware myself, so I can't test this, but he
claims it works. I'm not sure if allowing guest to enable/disable expansion ROM
is safe thing to do, but the comment in rom_write for me suggests it is but
wasn't considered necessary. Other than this uncertainty, the patches looks
good for me.
