Hi Stephen,
Thank you for reporting this. :)
I was aware of this problem by the kbuild rebot, and I think this problem has been fixed by the following patch I sent yesterday, and merged into -mm tree this morning.
Since I could access the lkml web site today, I cannot get an url for you. Please tell me if your problem is not solved after applying this patch. :)
Thanks. :)
[PATCH Bug fix 3/4] Bug fix: Remove the unused sanitize_zone_movable_limit() definition.
When CONFIG_HAVE_MEMBLOCK_NODE_MAP is not defined, sanitize_zone_movable_limit() is also not used. So remove it.
