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
