-Subject: [PATCH] drm/i915: Disallow pin ioctl completely for kms drivers
-
-The problem here is that SNA pins batchbuffers to etch out a bit more
-performance. Iirc it started out as a w/a for i830M (which we've
-implemented in the kernel since a long time already). The problem is
-that the pin ioctl wasn't added in

-    drm/i915: Prevent negative relocation deltas from wrapping
-
-Fix this by simply disallowing pinning from userspace so that the
-kernel is in full control of batch placement again. Especially since
-distros are moving towards running X as non-root, so most users won't
-even be able to see any benefits.
-
-UMS support is dead now, but we need this minimal patch for
-backporting. Follow-up patch will remove the pin ioctl code
-completely.
-
-Note to backporters: You must have both
