From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Fix a div-by-zero on gen2, and make the L-shaped memory detection actually work on cl/ctg. Atm the SWIZZLE_UNKNOWN stuff just trips some GEM_BUG_ONs. This doesn't fix those but since I populate all my memory channels symmetrically I get to avoid the GEM_BUG_ONs by correctly detecting that I don't have an L-shaped memory configuration.
