We need to have some Makefile logic to only enable -mprofile-kernel when it's known to work, ie. for versions where the notrace fix is in. Looking at GCC history it looks like the fix is in 4.9.0 and anything later. But a version check doesn't work with patched distro/vendor toolchains. So we probably need some sort of runtime check. cheers -- To unsubscribe from this list: send the line "unsubscribe live-patching" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
