Subject: [PATCH 4/4] ARM: set --be8 when linking modules
Date: Mon, 22 Jul 2013 17:33:53 +0100 [thread overview]
Message-ID: <1374510833-25716-5-git-send-email-ben.dooks@codethink.co.uk> (raw)
In-Reply-To: <1374510833-25716-1-git-send-email-ben.dooks@codethink.co.uk>
To avoid having to make every text section swap the instruction order
of all instructions, make sure modules are built also built with --be8
(as is the current kernel final link).
If we do not do this, we would end up having to swap all instructions
when loading a module, instead of just the instructions that we are
applying ELF relocations to.
