Subject: [PATCH 11/16] arm: mark heap and frametable limits as read mostly
Date: Mon, 3 Sep 2012 13:30:51 +0000 [thread overview]
Message-ID: <1346679056-8108-11-git-send-email-ian.campbell@citrix.com> (raw)
In-Reply-To: <1346678886.32462.9.camel@zakaz.uk.xensource.com>
These are used in virt_to_page and page_to_virt so I imagine there's
some small benefit to this (but I've not measured)
