Merge branch 'drm-etnaviv-next' of git://git.pengutronix.de/lst/linux into drm-next

- fix dma-buf export path to return correct SG table
- trivially implement direct dma-buf mapping
- allow DRAW_INSTANCED commands in validator
- make the driver work on i.MX6SX, yielding a working 2D/3D stack
together with Mareks MXS DRM driver

* 'drm-etnaviv-next' of git://git.pengutronix.de/lst/linux:
  MAINTAINERS: add etnaviv mailinglist
  drm/etnaviv: move linear window on MC1.0 parts if necessary
  drm/etnaviv: don't invoke OOM killer from dump code
  drm/etnaviv: fix gem_prime_get_sg_table to return new SG table
  drm/etnaviv: Allow DRAW_INSTANCED commands
  drm/etnaviv: implement dma-buf mmap
