Subject: [PATCH 02/11] acpi: Print hotplug info in SRAT.
Date: Fri, 5 Apr 2013 17:39:52 +0800	[thread overview]
Message-ID: <1365154801-473-3-git-send-email-tangchen@cn.fujitsu.com> (raw)
In-Reply-To: <1365154801-473-1-git-send-email-tangchen@cn.fujitsu.com>

The Hot Pluggable field in SRAT points out if the memory could be
hotplugged while the system is running. It is useful to print out
this info when parsing SRAT.
