Subject: [PATCH] Remove arch independent NODES_SPAN_OTHER_NODES
Date: Thu, 17 Nov 2005 14:41:38 -0800 [thread overview]
Message-ID: <20051117224138.GA5393@w-mikek2.ibm.com> (raw)
The NODES_SPAN_OTHER_NODES config option was created so that DISCONTIGMEM
could handle pSeries numa layouts. However, support for DISCONTIGMEM has
been replaced by SPARSEMEM on powerpc. As a result, this config option and
supporting code is no longer needed.
I have already sent a patch to Paul that removes the option from powerpc
specific code. This removes the arch independent piece. Doesn't really
matter which is applied first.
