From 076d2ea6829855ee14ebd65230146eb27ee16750 Mon Sep 17 00:00:00 2001 From: Vincent Wiemann Date: Sat, 9 Jun 2018 22:56:47 +0200 Subject: [PATCH] mips: fix dynamic ftrace The kernel patch *-mips_module_reloc.patch breaks dynamic ftrace as dynamic ftrace depends on -mlong-calls. See http://patchwork.linux-mips.org/patch/675/ Thus we always set -mlong-calls if the kernel is being compiled with dynamic ftrace support.
