CONFIG_FORCE_MAX_ZONE_ORDER was set to 13 because of hugetlbfs No, I just wanted to make sure it wasn't something that you just set for no particular reason. Hmm... is 16MB big enough for hugetlbfs? I presume PAGE_SIZE is still 4KB, so a value of 13 is just 16MB. -- Timur Tabi Linux kernel developer at Freescale
