FWIW, I have been including versions of this series in my s390 dev environments for a number of months now and have also been building my s390 pci iommufd nested translation series on top of this, so it's seen quite a bit of testing from me at least.

Agreed; I'll trust your reviews for the s390-specific parts, so indeed
it looks like this should have all it needs now and is ready for a nice
long soak in -next once Joerg opens the tree for 6.7 material.
