Cover letter [PATCH v2 0/3] improvements about lowmem_reserve and /proc/zoneinfo
In this post, I just drop the patch 4 and patch 5 in old v1 since David and Michal worried moving per-node stats to the front of /proc/zoneinfo has potential to break the existing user space scripts. For patch 1~3, there's no change, seems no risk is found out so far, so just keep them and repost.
