Subject: [patch] ARM: fix module-bound check in setting page attributes
Date: Mon, 04 May 2015 10:52:31 +0800 [thread overview]
Message-ID: <019401d08615$5e093000$1a1b9000$@alibaba-inc.com> (raw)
In-Reply-To: <5543C529.4080203@labbott.name>
It was introduced in commit f2ca09f381a59
(ARM: 8311/1: Don't use is_module_addr in setting page attributes)
We have no need to check start twice, but see if end is also in range.
