  "message": "kbuild: avoid conflict between -ffunction-sections and -pg on gcc-4.7\n\nArnd Bergmann reported:\n  \"When ftrace is enabled and we build with gcc-4.7 or older, we\n  get a warning for each file on architectures that select\n  CONFIG_LD_DEAD_CODE_DATA_ELIMINATION:\n\n  warning: -ffunction-sections disabled; it makes profiling impossible [enabled by default]\n  \"\n\nSince commit c3f0d0bc5b01 (\"kbuild, LLVMLinux: Add -Werror to\ncc-option to support clang\"), warnings are treated as errors in\ncc-option checks.  CC_FLAGS_FTRACE is blindly added to KBUILD_CFLAGS,\nso $(call cc-option,-ffunction-sections,) should be moved below it\nin order to detect the conflict between the two options.\n\nReported-by: Arnd Bergmann \u003carnd@arndb.de\u003e\nSigned-off-by: Masahiro Yamada \u003cyamada.masahiro@socionext.com\u003e\n",
