Yes! That is the idea - to have the xen-pcifront upstream. Thought as
you experienced first hand, first the SWIOTLB need to be in the kernel
to make the PCI front patches work.

ready for upstream. They don't have all of the nice bells and whistles
that xen/next has - just the basics to get xen-pcifront working.
