Backporting all the detection logic is to invasive, but you could just go into drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c and forcefull use the other code path.
Just look out for "#ifdef CONFIG_SWIOTLB" checks and disable those.
Do you mean just taking the 4.15 code as is and replacing "#ifdef CONFIG_SWIOTLB" with "#if 0" in drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c or are you talking about using a different version of drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c ?
