From c2cbcf533a1d7443cf1d6aae1127491792601587 Mon Sep 17 00:00:00 2001 From: Laurent Dufour Date: Tue, 24 Jun 2014 10:53:59 +0200 Subject: [PATCH] powerpc/module: Fix TOC symbol CRC The commit 71ec7c55ed91 introduced the magic symbol ".TOC." for ELFv2 ABI. This symbol is built manually and has no CRC value computed. A zero value is put in the CRC section to avoid modpost complaining about a missing CRC. Unfortunately, this breaks the kernel module loading when the kernel is relocated (kdump case for instance) because of the relocation applied to the kcrctab values. This patch compute a CRC value for the TOC symbol which will match the one compute by the kernel when it is relocated - aka '0 - relocate_start' done in maybe_relocated called by check_version (module.c).
