Subject: [PATCH part2 1/4] acpi: Print Hot-Pluggable Field in SRAT.
Date: Thu, 8 Aug 2013 13:03:56 +0800 [thread overview]
Message-ID: <1375938239-18769-2-git-send-email-tangchen@cn.fujitsu.com> (raw)
In-Reply-To: <1375938239-18769-1-git-send-email-tangchen@cn.fujitsu.com>
The Hot-Pluggable field in SRAT suggests if the memory could be
hotplugged while the system is running. Print it as well when
parsing SRAT will help users to know which memory is hotpluggable.
