Merge tag 'drm-intel-fixes-2017-01-05' of git://anongit.freedesktop.org/git/drm-intel
Pull i915 drm fixes from Jani Nikula: "Here's a bunch of drm/i915 fixes for v4.10-rc3. It includes GVT-g fixes. My new year's resolution is to start using signed tags for pulls. If that feels like a déjà vu, it's ((new year's) resolution), not (new (year's resolution))" [ Taking this directly from Jani because Dave Airlie is only partially connected right now. - Linus ] * tag 'drm-intel-fixes-2017-01-05' of git://anongit.freedesktop.org/git/drm-intel: drm/i915: Prevent timeline updates whilst performing reset drm/i915: Silence allocation failure during sg_trim() drm/i915: Don't clflush before release phys object drm/i915: Fix oops in overlay due to frontbuffer tracking drm/i915: Fix oopses in the overlay code due to i915_gem_active stuff drm/i915: Initialize overlay->last_flip properly drm/i915: Move the min_pixclk[] handling to the end of readout drm/i915: Force VDD off on the new power seqeuencer before starting to use it drm/i915/gvt: fix typo in cfg_space range check drm/i915/gvt: fix an issue in emulating cfg space PCI_COMMAND drm/i915/gvt/kvmgt: trival: code cleanup drm/i915/gvt/kvmgt: prevent double-release of vgpu drm/i915/gvt/kvmgt: check returned slot for gfn drm/i915/gvt/kvmgt: dereference the pointer within lock drm/i915/gvt: reset the GGTT entry when vGPU created drm/i915/gvt: fix an error in opregion handling
