| |
2.6.30-stable review patch. If anyone has any objections, please let us know.
------------------
From: Paul Mundt <lethal@linux-sh.org>
commit 35f2c2f6f6ae13ef23c4f68e6d3073753077ca43 upstream.
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.
