There are already PCI probe and remove callbacks in dom0 (c/s 593 in
linux-2.6.18-xen.hg). So it is not necessary to enumerate devices for dom0 in
Xen.
Espen had a patch (c/s 17975) to do the same thing, but his patch was reverted
in order to allow old dom0 kernels to work with iommu-capable platforms. Xen
3.3 has been released for a few months, I think it's time to clean up it. The
rebased patch is attached.
Keir, what's your opinion?
