This patch is in regard to bugme.osdl.org bug 619, link here:

http://bugme.osdl.org/show_bug.cgi?id=619

This is the first of two patches to fix this bug.  This patch changes 
the nine files that #include <asm/topology.h> to #include 
<linux/topology.h>.  It also creates include/linux/topology.h, but 
solely as a shell.  The next patch fills it in.
