+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.
