   - stolen memory fix

  imx:
   - regression fix

  qxl:
   - remove a bad warning

  etnaviv:
   - VM locking fix"

* tag 'drm-fixes-2019-05-31' of git://anongit.freedesktop.org/drm/drm:
  drm/amdgpu: reserve stollen vram for raven series
  drm/etnaviv: lock MMU while dumping core
  drm/imx: ipuv3-plane: fix atomic update status query for non-plus i.MX6Q
  drm/qxl: drop WARN_ONCE()
  drm/amd/display: Don't load DMCU for Raven 1 (v2)
