Subject: [PATCH] Revert: "kexec: lengthen the kernel command line image"
Date: Wed, 27 Mar 2013 20:42:28 +0800	[thread overview]
Message-ID: <5152E934.6000602@gmail.com> (raw)

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

This reverts commit 49320340f705694e387d794f7f19d407ad9baefa. The change
of COMMAND_LINE_SIZE cannot solve Cliff's problem since the kernel side
has the restriction, so it is useless. Let's recover the original value
defined by kernel side.
