From 6879dc137ea4efad65cab8bf8a7c0b742bcf92cc Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Tue, 21 Jun 2005 17:15:30 -0700 Subject: [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.
