Patches 1 and 2 are already being reviewed elsewhere. Discussion on 2nd patch made me revive something I started after comment from Ville at https://patchwork.freedesktop.org/patch/428168/?series=88988&rev=1#comme...
This removes CNL completely from the driver, while trying to rename functions and macros where appropriate (usually to GLK when dealing with display or with ICL otherwise). It starts with display, which is more straightforward, and then proceed to the rest of i915.
diff stat removing 1600 lines of dead code seems to pay the pain of doing this.
