ce697cce - kbuild: remove head-y syntax

Sat, 24 Sep 2022 18:19:15 +0000

kbuild: remove head-y syntaxKbuild puts the objects listed in head-y at the head of vmlinux.Conventionally, we do this for head*.S, which contains the kernel entrypoint.A counter approach is to control the section order by the linker script.Actually, the code marked as __HEAD goes into the ".head.text" section,which is placed before the normal ".text" section.I do not know if both of them are needed. From the build systemperspective, head-y is not mandatory. If you can achieve the proper codeplacement by the linker script only, it would be cleaner.I collected the current head-y objects into head-object-list.txt. It isa whitelist. My hope is it will be reduced in the long run.Signed-off-by: Masahiro Yamada Tested-by: Nick Desaulniers Reviewed-by: Nicolas Schier List of files: /linux-6.15/arch/csky/Makefile

8212f898 - kbuild: use more subdir- for visiting subdirectories while cleaning

Wed, 13 Oct 2021 06:36:22 +0000

kbuild: use more subdir- for visiting subdirectories while cleaningDocumentation/kbuild/makefiles.rst suggests to use "archclean" forcleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement.Since commit d92cc4d51643 ("kbuild: require all architectures to havearch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick forall architectures. This can take advantage of the parallel option (-j)for "make clean".I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep"target no longer exists.Signed-off-by: Masahiro Yamada Reviewed-by: Kees Cook Acked-by: Geert Uytterhoeven Acked-by: Michael Ellerman (powerpc) List of files: /linux-6.15/arch/csky/Makefile

csky: Fixup calltrace panicThe implementation of show_stack will panic with wrong fp:addr = *fp++;because the fp isn't checked properly.The current implementations of show_stack, wchan and stack_tracehaven't been designed properly, so just deprecate them.This patch is a reference to riscv's way, all codes are modified fromarm's.

bd305f25 - kconfig: make arch/*/configs/defconfig the default of KBUILD_DEFCONFIG

kconfig: make arch/*/configs/defconfig the default of KBUILD_DEFCONFIGUntil recently, if KBUILD_DEFCONFIG was not set by the arch Makefile,the default path arch/*/defconfig was used.The last users of the default are gone by the following commits:- Commit f3e20ad67b4c ("s390: move arch/s390/defconfig to arch/s390/configs/defconfig")- Commit 986a13769c4b ("alpha: move arch/alpha/defconfig to arch/alpha/configs/defconfig")Let's set arch/*/configs/defconfig as a new default.
