In my environment, my patch applies to linux-2.6.18-xen(changeset:855).
Could you try to apply the attached file? The file is the output of
'hg' command and I tested that the file applies.

This patch supports SBDF with "guestdev=" boot parameter and removes
"reassigndev=" boot parameter.
Currently there are three boot parameters which specifics PCI device
for PCI pass-through.
pciback.hide=
guestdev=
reassigndev=
I'd like to simplify them before xen 3.4 is released. To achieve this,
I'd like to make "guestdev=" boot parameter support SBDF, and remove
"reassigndev=".
When we don't need to reassign resources and use device path,
pciback.hide= boot parameter can be used. The parameter is also needed
for backward compatibility.
pciback.hide=(00:01.0)(00:02.0)
When we need to reassign resources or use device path, guestdev= boot
parameter can be used. reassign_resources boot parameter is needed to
reassign resources, too.
guestdev=00:01.0,00:02.0 reassign_resources
guestdev=PNP0A08:0-1.0,PNP0A08:0-2.0
guestdev=PNP0A08:0-1.0,PNP0A08:0-2.0 reassign_resources
With this patch, Isaku-san will not need to add guestioemuldev
boot parameter for IO space multiplexing, though it will be necessary
to add a flag and omit func# from guestdev.
