A couple notes with respect to this series:

- The first 2 patches I think are needed because it addresses a regression

- This paragraph is meant to state that this doesn't support vIOMMU, and so I
haven't changed in that area. I am assuming that when the vIOMMU will get resent
for 9.2 where I would address the IOMMUFD counterpart.

In case this be merged, the next Qemu stages after this series are:

1) Mixed mode of VF with IOMMUFD dirty tracking
2) vIOMMU support (with the relaxing vIOMMU patch and IOMMUFD support)

It's not listed in terms of priority, just wanted to make it obvious on the gaps
that are on my list.
