Since there's no cover letter to reply to, this one will need to do. What
I'm missing in the series is leveraging of the (limited) cleanup potential.
You're obsoleting the PT_IRQ_TYPE_MSI sub-case of
XEN_DOMCTL_{,un}bind_pt_irq. Respective libxc functions could now call the
libdevicemodel ones, rather than invoking those domctl-s. The domctl-s
could then reject attempts to use that sub-case.
