From 495dace544bcf0a036187bc5b78a5fab6425f375 Mon Sep 17 00:00:00 2001 From: Josh Poimboeuf Date: Tue, 19 Jun 2018 10:47:50 -0500 Subject: objtool: Add machine_real_restart() to the noreturn list commit 684fb246578b9e81fc7b4ca5c71eae22edb650b2 upstream. machine_real_restart() is annotated as '__noreturn", so add it to the objtool noreturn list. This fixes the following warning with clang and CONFIG_CC_OPTIMIZE_FOR_SIZE=y: arch/x86/kernel/reboot.o: warning: objtool: native_machine_emergency_restart() falls through to next function machine_power_off() Reported-by: Matthias Kaehlcke Signed-off-by: Josh Poimboeuf Signed-off-by: Thomas Gleixner Tested-by: Matthias Kaehlcke Reviewed-by: Matthias Kaehlcke Link: https://lkml.kernel.org/r/791712792aa4431bdd55bf1beb33a169ddf3b4a2.1529423255.git.jpoimboe@redhat.com Signed-off-by: Greg Kroah-Hartman --- tools/objtool/check.c | 1 + 1 file changed, 1 insertion(+) (limited to 'tools') diff --git a/tools/objtool/check.c b/tools/objtool/check.c index 95326c6a7a24..aabbd6fcaa96 100644 --- a/tools/objtool/check.c +++ b/tools/objtool/check.c @@ -165,6 +165,7 @@ static int __dead_end_function(struct objtool_file *file, struct symbol *func, "__reiserfs_panic", "lbug_with_loc", "fortify_panic", + "machine_real_restart", }; if (func->bind == STB_WEAK) -- cgit v1.2.3
