From: Vincent Wiemann Date: Sat, 9 Jun 2018 20:56:47 +0000 (+0200) Subject: mips: fix dynamic ftrace X-Git-Tag: v19.07.0-rc1~3395 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=076d2ea6829855ee14ebd65230146eb27ee16750;p=openwrt%2Fstaging%2Fhauke.git 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.
