Benjamin Herrenschmidt 6879dc137e [PATCH] ppc32: Kill embedded system.map, use kallsyms 
This patch kills the whole embedded System.map mecanism and the
bootloader-passed System.map that was used to provide symbol resolution in
xmon.  Instead, xmon now uses kallsyms like ppc64 does.

No hurry getting that in Linus tree, let it be tested in -mm for a while
first and make sure it doesn't break various embedded configs.
