I don't see any patch.

Looks like the amdgpu driver has never fully initialized GDS support for
SI family GPUs, and this now triggers the DRM_MM_BUG_ON which was added
to drm_mm_init in 4.11.

AMD folks, should this be addressed by fleshing out SI GDS support, or
by completely disabling GDS initialization for SI?
