Subject: [Qemu-devel] [PATCH v2 3/4] numa: Store boot memory address range in node_info
Date: Fri, 19 Jun 2015 10:40:23 +0530 [thread overview]
Message-ID: <1434690624-8628-4-git-send-email-bharata@linux.vnet.ibm.com> (raw)
In-Reply-To: <1434690624-8628-1-git-send-email-bharata@linux.vnet.ibm.com>
Store memory address range information of boot memory in address
range list of numa_info.
This helps to have a common NUMA node lookup by address function that
works for both boot time memory and hotplugged memory.
