From 054f367a32381b5640c5d150fe0b7ba285564998 Mon Sep 17 00:00:00 2001 From: Daniel Axtens Date: Wed, 12 Jul 2017 14:36:04 -0700 Subject: [PATCH] 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.
