    Subjectrefactor the i915 GVT support and move to the modern mdev API v2
    Date
    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.

    Git tree:

    git://git.infradead.org/users/hch/misc.git i915-gvt

    Gitweb:

    http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/i915-gvt

    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.
