From acd41539d630688e9891003c9b51cace3e113316 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Wed, 22 Jun 2016 15:47:20 +0300 Subject: linux: arc: disable kernel unwinding to fix modules loading With update of binutils for ARC (this is now based on upstream 2.26) we noticed issues with loadable kernel modules. Something like that was happening: --------------------->8------------------- mbcache: unknown relocation: 49 insmod: can't insert './mbcache.ko': invalid module format --------------------->8------------------- More details could be found in that discussion in binutils mailing list: http://thread.gmane.org/gmane.comp.gnu.binutils/74662 As of now the simplest work-around is to disable in-kernel unwinder for now. That will at least allow us to use modules again.
