[PATCH v2 0/1] Dont allocate pages on a offline node

[Nico Pache]

Prevent page allocations from occuring on an offlined by adding a check
to confirm the node is online and if not, use the closest node. Some
further work is needed for my previous solution to be complete. This
will provide a fix to the problem while the more complete solution is
being worked on.

V2:
 * drop the first patch that will introduce a regression by adding a
   branch in the hotpath.
 * Remove the for_each_online_nodes introduced as that will require
   further work for memcg and hotplug to work correctly. Long term a
   rework will be needed to either allocate all pgdatas or update all
   memcgs when a new node is onlined.
