If anyone has any objections, please let me know. ------------------ Content-Length: 983 Lines: 33 From: Dave Jones commit af0e5d565d2fffcd97d1e2d89669d627cc04e8b8 upstream. Disable the new -Wunused-but-set-variable that was added in gcc 4.6.0 It produces more false positives than useful warnings. This can still be enabled using W=1 [gregkh - No it can not for 2.6.32, but we don't care] Signed-off-by: Dave Jones Acked-by: Sam Ravnborg Tested-by: Sam Ravnborg Signed-off-by: Michal Marek Signed-off-by: Greg Kroah-Hartman --- Makefile | 3 +++ 1 file changed, 3 insertions(+) --- a/Makefile +++ b/Makefile @@ -537,6 +537,9 @@ ifndef CONFIG_CC_STACKPROTECTOR KBUILD_CFLAGS += $(call cc-option, -fno-stack-protector) endif +# This warning generated too much noise in a regular build. +KBUILD_CFLAGS += $(call cc-option, -Wno-unused-but-set-variable) + ifdef CONFIG_FRAME_POINTER KBUILD_CFLAGS += -fno-omit-frame-pointer -fno-optimize-sibling-calls else
