[PATCH] mm: remove arch independent NODES_SPAN_OTHER_NODES 

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been replaced by SPARSEMEM on powerpc.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.
