It's not a bug, it's a feature: to work around a Bulldozer cache aliasing performance problem we have to keep bits 12,13,14 equal for all mappings in the system. Your patch improves upon that fix: by per-boot randomizing the constant portion of the randomized range. Btw., does anyone know how relevant the performance fix is these days? A simpler improvement would be to remove the workaround altogether and recover proper randomization of bits 12,13,14.
