Subject: [PATCH] of: Provide default of_node_to_nid() when CONFIG_NUMA is not set
Date: Sat, 24 Jul 2010 09:43:31 -0600 [thread overview]
Message-ID: <20100724154331.22701.3409.stgit@angua> (raw)
of_node_to_nid() is only relevant for NUMA. Don't force architectures to
implement it if CONFIG_NUMA is not set.
