Hi Daniel, kernel build 4.4.20 - I am still seeing this warning: drivers/gpu/drm/i915/intel_display.c: In function ‘intel_plane_obj_offset’: drivers/gpu/drm/i915/intel_display.c:2969:11: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] offset = (unsigned char *)vma->node.start; but according to here: https://patchwork.kernel.org/patch/7897461/ this has been fixed up. Any reason why it hasn't in the latest 4.4.x longterm tree? Thanks, Nick -- Gosh that takes me back... or is it forward?

Took me a while to find it if this is it - a bit of a re-write in the whole file I think: https://github.com/torvalds/linux/commit/44eb0cb9620c6a53ec8e7073262e2af8079b727f Thanks, Nick -- Gosh that takes me back... or is it forward?

Why not just use 4.7? Why are you stuck at 4.4? And is this a real bug in 4.4 or just a build warning? thanks, greg k-h

Why are you stuck at 4.4? I only recently moved over to 4.4 from 3.18.x as it's longterm support. I may try 4.7 over the weekend - or maybe even just use the patchwork diff on my own local builds. > And is this a real bug in 4.4 or just a build warning? No, it's not a bug (that I have found or seen, anyway), just GCC squinnying. Thanks for your help, and sorry for the noise. Nick -- Gosh that takes me back... or is it forward?
