I did some basic testing including running a 4K video on Chrome whilst
running intel_gpu_top. The intel_gpu_top program doesn't display
anything on 4.12 either with or without the patch as neither I nor
Canonical enabled CONFIG_DRM_I915_ALPHA_SUPPORT. Do you think that the
stable tag should exclude 4.12 because of the 'alpha quality support'
and if so do you want a V2 of the patch?

Best regards,
Ian
