Just one special case (since i915 lost its ums code, yay): - radeon: Has slots for the old ums ioctls which don't have DRM_UNLOCKED, but all filled with drm_invalid_op. So ok to drop it everywhere. Every other kms driver just has DRM_UNLOCKED for all their ioctls, as they should. v2: admgpu happened, include that one too. And i915 lost its UMS support which means we can change all the i915 ioctls too. v3: Rebased on top of new vmwgfx DX interface extensions. v4: Rebase on top of render-node support in exynos.
