Subject: memcg: use __GFP_NOWARN in page cgroup allocation
From: KAMEZAWA Hiroyuki <kamezawa.hiroyu@xxxxxxxxxxxxxx>
page_cgroup's page allocation at init/memory hotplug uses kmalloc() and
vmalloc(). If kmalloc() failes, vmalloc() is used.
This is because vmalloc() is very limited resource on 32bit systems.
We want to use kmalloc() first.
But in this kind of call, __GFP_NOWARN should be specified.
