In my pmap_pv API, there's no need to change pmap_enter. All you need
to do is to call pmap_pv_track on driver attach to mark the pages as
device pages. Then pmap can do the bookkeeping

Considering these, PV should be kept in struct vm_physseg, instead of
struct vm_page, ideally.
The only difficulty with that is that you still need a fast way to go
from a struct vm_page to the PV tracking
