In80c89909f3("brw: fixup immediate bindless surface handling") I forgot that we have a special usage for the only _SS surface (the scratch surface). Because it's only delivered in the 31:10 bits of R0 and because we want to minimize the amount of shader instructions for scratch messages, the surface offset in shifted right by the driver to align things properly for the 31:6 extended descriptor format. This is unfortunately incompatible with the full 32bit format of ExBSO. So this surface type currently cannot be considered bindless. We might revisit later if we start using _SS surfaces for other things.
