Hi all,

This are the leftovers from my pull that landed in 5.12:

https://lore.kernel.org/dri-devel/CAKMK7uHQ=6OJcRguCUtiB456RWdCfwSNEXV8pQsfsPodTJ6uxw@mail.gmail.com/

Only changes compared to the old submission are:
- dropped vfio and kvm patch
- add patch to just remove follow_pfn at the end

Assuming no objections I'd like to lande these three patches in my topic
branch for 5.13, for sufficient amounts of testing in linux-next before
the merge window.

Ack/review especially on the two mm patches very much thought after.

Cheers, Daniel
