From 505a314fb28ce122091691c51426fa85c084e115 Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 8 Oct 2018 15:08:31 +1100 Subject: powerpc: Fix HMIs on big-endian with CONFIG_RELOCATABLE=y HMIs will crash the kernel due to BRANCH_LINK_TO_FAR(hmi_exception_realmode) Calling into the OPD instead of the actual code.
