That's precisely my plan. The conversion of pci-assign to the new APIs
is too hairy to combine it with a refactoring and upstream push. But
this depends on this series being merged back into qemu-kvm first.

This and also the previous MSI work will cause some merge conflicts.
Once upsteam accepted these series, I will provide the usual merge work
as pull request.

There are also some other "smaller" pieces to prepare for device
assignment (e.g. PCI IRQ routing hooks, full PCI address properties)
that I'm preparing for upstream. Will send some of them later.
