Oh, that is pretty gross. I guess we can just comment out asm-generic's
definition of that macro, as pretty much every architecture is defining it
for itself anyway.

Can you try that? Just have it defined to 1 in
asm-x86_64/mach-xen/asm/pci.h, and comment out the definition in

If that works I'll apply the fix to our tree with appropriate comments.

This isn't going to fly upstream, or probably even in vendor kernels, so
longer term the dummy device in pciback is probably going to be required.
