To all,

The next few forwarded messages comprise my responses to Greg's
questions about the patch I submitted to deal with pci devices
that do not respond correctly to x86 mmconf accesses.

Please accept my apologies for not having including the community
in my original responses.

Yes, of course. I missed that. Thank you.

Should I resubmit that one patch? Or would you prefer I resubmit
the whole patch set?

I take that back.

This struct must be declared extern because it is referenced in
arch/x86/pci/common.c by pcibios_fix_bus_scan_quirk()

Sure, but you do not reference it in this patch, right?  So it's not
needed until you actually use it, so just include it in the patch that
you are needing it in.
