Thanks, I've taken them. v7 was sent out.

Yes. I cherry-pick his iommufd_hwpt to 6.3-rc2 and then try a
merge and then cherry-pick the replace and nesting series from
your above branch. Though the order between cdev and
iommufd_hwpt not perfect, we may use it as a wip baseline
when we try to address the comments w.r.t. nesting and
replace series.
