From 1820568178aca33d03f08482159d49320faff0a4 Mon Sep 17 00:00:00 2001 From: Behan Webster Date: Wed, 24 Sep 2014 01:06:46 +0100 Subject: ARM: 8158/1: LLVMLinux: use static inline in ARM ftrace.h With compilers which follow the C99 standard (like modern versions of gcc and clang), "extern inline" does the wrong thing (emits code for an externally linkable version of the inline function). In this case using static inline and removing the NULL version of return_address in return_address.c does the right thing.
