Merge tag 'drm-next-2020-10-15' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "Not a major amount of change, the i915 trees got split into display and gt trees to better facilitate higher level review, and there's a major refactoring of i915 GEM locking to use more core kernel concepts (like ww-mutexes). msm gets per-process pagetables, older AMD SI cards get DC support, nouveau got a bump in displayport support with common code extraction from i915. Outside of drm this contains a couple of patches for hexint moduleparams which you've acked, and a virtio common code tree that you should also get via it's regular path.
