From: Daniel Axtens <dja@xxxxxxxxxx> Subject: powerpc: don't fortify prom_init prom_init is a bit special; in theory it should be able to be linked separately to the kernel. To keep this from getting too complex, the symbols that prom_init.c uses are checked. Fortification adds symbols, and it gets quite messy as it includes things like panic(). So just don't fortify prom_init.c for now.
