Dear i915 maintainers,

I wanted to ping you regarding this patch series. If there are no 
comments for the series from you side, would it be possible to land 
Intel-specific and generic patches into drm-intel tree? We will continue 
working on the msm specific parts and merge them through the msm tree.
