drm-intel-next-2018-09-06-1:
UAPI Changes:
- GGTT coherency GETPARAM: GGTT has turned out to be non-coherent for some
  platforms, which we've failed to communicate to userspace so far. SNA was
  modified to do extra flushing on non-coherent GGTT access, while Mesa will
  mitigate by always requiring WC mapping (which is non-coherent anyway).
- Neuter Resource Streamer uAPI: There never really were users for the feature,
  so neuter it while keeping the interface bits for compatibility. This is a
  long due item from past.

Cross-subsystem Changes:
- Backmerge of branch drm-next-4.19 for DP_DPCD_REV_14 changes

Core Changes:
- None

- Use a cached mapping for the physical HWS on older gens (Chris)
- Force slow path of writing relocations to buffer if unable to write to userspace (Chris)
- Do a full device reset after being wedged (Chris)
- Keep forcewake counts over reset (in case of debugfs user) (Imre, Chris)
- Avoid false-positive errors from power wells during init (Imre)
- Reset engines forcibly in exchange of declaring whole device wedged (Mika)
- Reduce context HW ID lifetime in preparation for Icelake (Chris)

- Exercise resetting in the middle of a wait-on-fence in selftests (Chris)
- Fix coherency issues on selftests for Baytrail (Chris)
- Various other GEM fixes / self-test updates (Chris, Matt)
- GuC doorbell self-tests (Daniele)
- PSR mode control through debugfs for IGTs (Maarten)
- Degrade expected WM latency errors to DRM_DEBUG_KMS (Chris)
- Cope with errors better in MST link training (Dhinakaran)
- Fix WARN on KBL external displays (Azhar)
- Power well code cleanups (Imre)
