Subject: [PATCH v1 3/3] powerpc: fix node_possible_map limitations
Date: Tue, 15 Nov 2016 10:44:05 +1100 [thread overview]
Message-ID: <1479167045-28136-4-git-send-email-bsingharora@gmail.com> (raw)
In-Reply-To: <1479167045-28136-1-git-send-email-bsingharora@gmail.com>
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")
