Merge branch 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux into drm-next
Highlights this time:
1. Fix for a nasty Kconfig dependency chain issue from Philipp.
2. Occlusion query buffer address added to the cmdstream validator by
Christian.
3. Fixes and cleanups to the job handling from me. This allows us to
turn on the GPU performance profiling added in the last cycle.
It is also prep work for hooking in the DRM GPU scheduler, which I hope
to land for the next cycle.
* 'etnaviv/next' of https://git.pengutronix.de/git/lst/linux: (32 commits)
