[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.
