This is the 4.18.7 stable release

i915 fixes

sound fixes for 4.19-rc3

Just a few small fixes:
- a fix for the recursive work cancellation in a specific HD-audio
  operation mode
- a fix for potentially uninitialized memory access via rawmidi
- the register bit access fixes for ASoC HD-audio

Merge tag 'gvt-next-2018-09-04'

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

But this pull also include fixes for DP SST, small VDSC register fix
and GVT's bucked with "BXT fixes, two guest warning fixes, dmabuf
format mod fix and one for recent multiple VM timeout failure."
