| Subject: nommu: Provide mmap_min_addr definition. |
| |
| 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. |
