[patch 69/71] nommu: Provide mmap_min_addr definition.

[Greg KH]

2.6.30-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Paul Mundt <lethal@xxxxxxxxxxxx>

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.
