Subject: [PART3 Patch 00/14] introduce N_MEMORY

From: Lai Jiangshan <laijs@...fujitsu.com>

This patch is part3 of the following patchset:
    https://lkml.org/lkml/2012/10/29/319

Part1 is here:
    https://lkml.org/lkml/2012/10/31/30

Part2 is here:
    http://marc.info/?l=linux-kernel&m=135166705909544&w=2

You can apply this patchset without the other parts.

we need a node which only contains movable memory. This feature is very
important for node hotplug. So we will add a new nodemask
for all memory. N_MEMORY contains movable memory but N_HIGH_MEMORY
doesn't contain it.

We don't remove N_HIGH_MEMORY because it can be used to search which
nodes contains memory that the kernel can use.

The movable node will implemtent in part4. So N_MEMORY is equal to N_HIGH_MEMORY
now.


Lai Jiangshan (14):
  node_states: introduce N_MEMORY
  cpuset: use N_MEMORY instead N_HIGH_MEMORY
  procfs: use N_MEMORY instead N_HIGH_MEMORY
  memcontrol: use N_MEMORY instead N_HIGH_MEMORY
  oom: use N_MEMORY instead N_HIGH_MEMORY
  mm,migrate: use N_MEMORY instead N_HIGH_MEMORY
  mempolicy: use N_MEMORY instead N_HIGH_MEMORY
  hugetlb: use N_MEMORY instead N_HIGH_MEMORY
  vmstat: use N_MEMORY instead N_HIGH_MEMORY
  kthread: use N_MEMORY instead N_HIGH_MEMORY
  init: use N_MEMORY instead N_HIGH_MEMORY
  vmscan: use N_MEMORY instead N_HIGH_MEMORY
  page_alloc: use N_MEMORY instead N_HIGH_MEMORY change the node_states
    initialization
  hotplug: update nodemasks management
