Merge branch 'drm-next-4.1' of git://people.freedesktop.org/~agd5f/linux into drm-next
Some final bits for 4.1. Some fixes for userptrs and allow a new packet for VCE to enable some new features in mesa. * 'drm-next-4.1' of git://people.freedesktop.org/~agd5f/linux: drm/radeon: allow creating overlapping userptrs drm/radeon: add userptr config option drm/radeon: add video usability info support for VCE
