Subject: [Bug fix PATCH 2/2] acpi, movablemem_map: Set numa_nodes_hotplug nodemask when using SRAT info.
Date: Tue, 19 Feb 2013 21:01:44 +0800 [thread overview]
Message-ID: <1361278904-8690-3-git-send-email-tangchen@cn.fujitsu.com> (raw)
In-Reply-To: <1361278904-8690-1-git-send-email-tangchen@cn.fujitsu.com>
We should also set movablemem_map.numa_nodes_hotplug nodemask when we
insert a hot-pluggable range in SRAT into movablemem_map.map[].
