Subject: [PATCH 3/5] OpenRISC: Export memory_start and memory_end
Date: Fri, 2 Mar 2012 01:55:13 +0100 [thread overview]
Message-ID: <1330649715-32438-3-git-send-email-richard@nod.at> (raw)
In-Reply-To: <1330649715-32438-1-git-send-email-richard@nod.at>
At least virt_addr_valid() makes use of memory_end.
