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

this cycle has been fairly calm in etnaviv land with most of the action
happening on the userspace side.

Notable changes:
- Improvements to CONFIG option handling to make it harder for users to
shoot themselves in the foot due to kernel misconfiguration.
- Tweaked GEM object population, so that userspace can take considerate
action when memory allocation fails, rather than waking the raging OOM
killer beast.

* 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux:
  drm/etnaviv: switch GEM allocations to __GFP_RETRY_MAYFAIL
  drm/etnaviv: don't fail GPU bind when CONFIG_THERMAL isn't enabled
  drm/etnaviv: switch to drm_*{get,put} helpers
  drm/etnaviv: select CMA and DMA_CMA if available
  drm/etnaviv: populate GEM objects on cpu_prep
  drm/etnaviv: reduce allocation failure message severity
  drm/etnaviv: don't trigger OOM killer when page allocation fails
