This is because unreachable code might # be the indication that objtool doesn't properly decode object text. # # text data bss dec hex filename # 9551585 3627834 224376 13403795 cc8693 vmlinux.before #

# Taking into account that other problems are encountered with that # 'asm goto' in WARN_ON(), including build failures, keeping that # change is not worth it allthough it is primarily a compiler bug. # # Revert it for now. # # mpe: Retain EMIT_WARN_ENTRY as a synonym for EMIT_BUG_ENTRY to reduce # churn, as there are now nearly as many uses of EMIT_WARN_ENTRY as # EMIT_BUG_ENTRY. # # Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> #
