That won't work like this. We use a virtual resource start for this
check here.

Just replace this whole test with calling amdgpu_bo_in_cpu_visible_vram().

Same here, just call amdgpu_bo_in_cpu_visible_vram() instead.

This doesn't belong into this patch and would break if only this patch
is applied.
Please move it into a later patch.
Apart from those comments that looks good now,
Christian.
