Subject: [PATCH 07/16] arm: use get_personality()
Date: Sat, 23 Feb 2008 16:14:10 +0800 [thread overview]
Message-ID: <12037545311452-git-send-email-xiyou.wangcong@gmail.com> (raw)
In-Reply-To: <1203754519825-git-send-email-xiyou.wangcong@gmail.com>
Use get_personality() macro instead of explicit reference
for arm code.
