Subject: [PATCH v2 7/7] s390: Remove setting for saved_max_pfn
Date: Sun, 26 May 2013 14:45:39 +0800	[thread overview]
Message-ID: <51A1AF93.70202@gmail.com> (raw)
In-Reply-To: <51A1AC4A.60506@gmail.com>

From: Zhang Yanfei <zhangyanfei@cn.fujitsu.com>

The only user of saved_max_pfn in s390 is read_oldmem interface but we
have removed that interface, so saved_max_pfn is now unneeded in s390,
and we needn't set it anymore.
