Subject: [PATCH] arm64: pageattr: Correctly adjust unaligned start addresses
Date: Thu, 11 Sep 2014 15:10:32 -0700 [thread overview]
Message-ID: <1410473432-13381-1-git-send-email-lauraa@codeaurora.org> (raw)
In-Reply-To: <54112831.6010800@codeaurora.org>
The start address needs to be actually updated after it
is detected to be unaligned. Adjust it and the end address
properly.
