Merge tag 'drm-intel-fixes-2017-07-27' of git://anongit.freedesktop.org/git/drm-intel into drm-fixes
i915 fixes for -rc3 Bit more than usual since we missed -rc2. 4x cc: stable, 2 gvt patches, but all fairly minor stuff. Last minute rebase was to add a few missing cc: stable, I did prep the pull this morning already and made sure CI approves. * tag 'drm-intel-fixes-2017-07-27' of git://anongit.freedesktop.org/git/drm-intel: drm/i915: Fix bad comparison in skl_compute_plane_wm. drm/i915: Force CPU synchronisation even if userspace requests ASYNC drm/i915: Only skip updating execobject.offset after error drm/i915: Only mark the execobject as pinned on success drm/i915: Remove assertion from raw __i915_vma_unpin() drm/i915/cnl: Fix loadgen select programming on ddi vswing sequence drm/i915: Fix scaler init during CRTC HW state readout drm/i915/selftests: Fix an error handling path in 'mock_gem_device()' drm/i915: Unbreak gpu reset vs. modeset locking drm/i915: Fix cursor updates on some platforms drm/i915: Fix user ptr check size in eb_relocate_vma() drm/i915/gvt: Extend KBL platform support in GVT-g drm/i915/gvt: Fix the vblank timer close issue after shutdown VMs in reverse
