[PATCH v2 7/8] drm/virtio: Support memory shrinking

[Emil Velikov]

Greetings everyone,

Food for thought: Would it make sense to have the madvise ioctl as
generic DRM one?
Looking around - i915, msm & panfrost already have one and the virtio
implementation [below] seems as generic as it gets.

This seems to be based on panfrost/msm yet names (bo_handle vs
handle), layout and documentation varies.
Why is that - copy/paste is cheap :-P
