Yeah, I understand that and as a short-term solution we maybe can add a check to verify that the goal and limits are under lowmem and fail with NULL if not, but it still is a broken interface and I'd rather not mess with it when memblock is already there. Converting to memblock usually isn't too much work although it expectedly involves some subtleties and fallouts for a while. Do you recall what the problem was with sparsemem and memblock? I don't think I'll directly work on arm but I'll be happy to help on memblock issues.
