I though that we agreed that Xen will take care of doing all the MMIO
mappings for HVMlite/PVHv2 guests:
http://lists.xenproject.org/archives/html/xen-devel/2016-02/msg01609.html
My first idea was to use the MMIO device mapping hypercall (just like
ARM) on the hardware domain, but I think we can get away without it on x86.
Roger.
