[PATCH v1 3/3] powerpc: fix node_possible_map limitations
From: Balbir Singh <bsingharora@gmail.com>
Date: 2016-11-14 23:44:28
Also in:
linux-mm
Subsystem:
linux for powerpc (32-bit and 64-bit), the rest · Maintainers:
Madhavan Srinivasan, Linus Torvalds
We've fixed the memory hotplug issue with memcg, hence
this work around should not be required.
Fixes: commit 3af229f2071f
("powerpc/numa: Reset node_possible_map to only node_online_map")
