Christoph, this is why I had to have LARGE_ALLOCS enabled on sparc64 all this time, for that MAX_OBJ_ORDER logic in mm/slab.c in order to get 512K and 1MB slab caches usable. This inconsistency is painful for platforms. If I enable LARGE_ALLOCS on sparc64 then SLAB works but it's a total waste for SLUB. Right now if I enable LARGE_ALLOCS, SLUB will break again due to that KMALLOC_SHIFT_HIGH bug we fixed the other week, Christophe can you at least push that fix to Linus if you haven't already? Thanks. - To unsubscribe from this list: send the line "unsubscribe sparclinux" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
