ng canonical addressing - both in case of softpin (verifying incoming offset) and when relocating (converting to canonical when updating offset returned to userspace). Unfortunately when considering the need for relocations, we're comparing offset from userspace (in canonical form) with drm_mm node (in non-canonical form), and as a result, we end up always relocating if our offsets are in the "problematic" range. Let's always convert the offsets to avoid the performance impact of relocations.
