Hi Anthony.
With the following 3 patches applied, xen panics.
0 A hypercall_for_vtd2.patch
1 A ia64-px-xen-setpxinfo-update.patch
2 A add_head_file_for_VTD2.patch
dom0->arch.pdev_list doesn't seem to be initialized.
diversity_vtd.patch has the corresponding line, but the hunk should
be included
[I added Kyouya and Akio to CC for comments on the hunk in vtlb.c]
