Linus rationale for this is: - - It's wrong because it will just make people turn off RETPOLINE, and the - asm updates - and return stack clearing - that are independent of the - compiler are likely the most important parts because they are likely the - ones easiest to target. - - And it's annoying because most people won't be able to do anything about - it. The number of people building their own compiler? Very small. So if - their distro hasn't got a compiler yet (and pretty much nobody does), the - warning is just annoying crap. - - It is already properly reported as part of the sysfs interface. The - compile-time warning only encourages bad things. - -Fixes: 76b043848fd2 ("x86/retpoline: Add initial retpoline support") -Requested-by: Linus Torvalds <torvalds@linux-foundation.org> -Signed-off-by: Thomas Gleixner <tglx@linutronix.de> -Cc: David Woodhouse <dwmw@amazon.co.uk> -Cc: Peter Zijlstra (Intel) <peterz@infradead.org> -Cc: gnomes@lxorguk.ukuu.org.uk -Cc: Rik van Riel <riel@redhat.com> -Cc: Andi Kleen <ak@linux.intel.com> -Cc: Josh Poimboeuf <jpoimboe@redhat.com> -Cc: thomas.lendacky@amd.com -Cc: Linus Torvalds <torvalds@linux-foundation.org> -Cc: Jiri Kosina <jikos@kernel.org> -Cc: Andy Lutomirski <luto@amacapital.net> -Cc: Dave Hansen <dave.hansen@intel.com> -Cc: Kees Cook <keescook@google.com> -Cc: Tim Chen <tim.c.chen@linux.intel.com> -Cc: Greg Kroah-Hartman <gregkh@linux-foundation.org> -Link: https://lkml.kernel.org/r/CA+55aFzWgquv4i6Mab6bASqYXg3ErV3XDFEYf=GEcCDQg5uAtw@mail.gmail.com -Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> ---- - arch/x86/Makefile | 2 -- - 1 file changed, 2 deletions(-) - -diff --git a/arch/x86/Makefile b/arch/x86/Makefile -index 1e1a733..cd22cb8 100644 ---- a/arch/x86/Makefile -+++ b/arch/x86/Makefile -@@ -187,8 +187,6 @@ ifdef CONFIG_RETPOLINE - RETPOLINE_CFLAGS += $(call cc-option,-mindirect-branch=thunk-extern -mindirect-branch-register) - ifneq ($(RETPOLINE_CFLAGS),) - KBUILD_CFLAGS += $(RETPOLINE_CFLAGS) -DRETPOLINE -- else -- $(warning CONFIG_RETPOLINE=y, but not supported by the compiler.
