From 822d5d5f19cb8de7f0fdad9db9dee2aad6d13a62 Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Sun, 18 May 2014 19:45:00 +0200 Subject: [PATCH] duma: not available on non-MMU platforms By design, building duma on Blackfin and other non-MMU platforms is quite useless: it uses page mappings to detect buffer overrun and use-after-free programming errors. Therefore, this commit simply marks duma as not available on non-MMU platforms.
