On patch creation, I had handled them literally, individually. Now they're blended into CC_FLAGS_FTRACE, which greatly simplified things. Done.

I can't think of anywhere we would want to disable -pg but not disable -mprofile-kernel? Or vice versa. cheers ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
[PATCH v7 07/10] ppc64 ftrace: disable profiling for some files
This patch complements the "notrace" attribute for selected functions. It adds -mprofile-kernel to the cc flags to be stripped from the command line for code-patching.o and feature-fixups.o, in addition to "-pg" Signed-off-by: Torsten Duwe--- arch/powerpc/lib/Makefile | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/powerpc/lib/Makefile b/arch/powerpc/lib/Makefile index a47e142..98e22b2 100644 --- a/arch/powerpc/lib/Makefile +++ b/arch/powerpc/lib/Makefile @@ -6,8 +6,8 @@ subdir-ccflags-$(CONFIG_PPC_WERROR) := -Werror ccflags-$(CONFIG_PPC64):= $(NO_MINIMAL_TOC) -CFLAGS_REMOVE_code-patching.o = -pg -CFLAGS_REMOVE_feature-fixups.o = -pg +CFLAGS_REMOVE_code-patching.o = -pg -mprofile-kernel +CFLAGS_REMOVE_feature-fixups.o = -pg -mprofile-kernel obj-y += string.o alloc.o crtsavres.o ppc_ksyms.o code-patching.o \ feature-fixups.o -- 1.8.5.6 ___ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
