Subject: [PATCH -next] nommu: Provide mmap_min_addr definition.
Date: Tue, 9 Jun 2009 17:48:56 +0900 [thread overview]
Message-ID: <20090609084856.GA18528@linux-sh.org> (raw)
With the "security: use mmap_min_addr indepedently of security models"
change, mmap_min_addr is used in common areas, which susbsequently blows
up the nommu build. This stubs in the definition in the nommu case as
well.
