It is indeed NULL at that point and as far as I can see it's an issue of
the fedora-kernel since there in arch/x86_64/mm/init-xen.c:mem_init()
"pci_iommu_alloc()" is called instead of "no_iommu_init()"!
I replaced pci_iommu_alloc() with the "pci_swiotlb_init()" /
"no_iommu_init()"-block from xen-unstable and now it works!
The fedora init-xen.c looks very different to the one on your repository
in many places, but I can't see if theses changes were intended or if
it's just an older revision in the fedora-tree.
