+Subject: [PATCH] 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.
