Subject: [PATCH RESEND 3/3] x86, mm: Move max_pfn_mapped definition to init.c.
Date: Mon, 2 Sep 2013 18:30:29 +0800	[thread overview]
Message-ID: <1378117829-9095-4-git-send-email-tangchen@cn.fujitsu.com> (raw)
In-Reply-To: <1378117829-9095-1-git-send-email-tangchen@cn.fujitsu.com>

min_pfn_mapped is defined in init.c, we can also define max_pfn_mapped here.
