Hi all,
the GVT code in the i915 is a bit of a mess right now due to strange
abstractions and lots of indirect calls. This series refactors various
bits to clean that up. The main user visible change is that almost all
of the GVT code moves out of the main i915 driver and into the kvmgt
module.
Tested on my Thinkpad with a Kaby Lake CPU and integrated graphics.

Gitweb:

Changes since v2:
- rebased on top of Linx 5.18-rc +
"Refactor GVT-g MMIO tracking table and handlers"
- don't fold the gvt Makefile into the main Makefile
- add the mdev patches to remove the legacy interface that is now
unused to the end of the series
Changes since v1:
- rebased on Linux 5.15
- allow the kvmgvt module to be loaded at any time and thus solve
the deadlock when both i915 amd kvmgvt are modular
- include the conversion to the modern mdev API
Note that I do expect to rebased this again against 5.16-rc1 once
released, but I'd like to get this out for review ASAP.
