$(call ld-option, --fix-cortex-a53-843419) in arch/arm64/Makefile is evaluated every time even for Make targets that do not need the linker, such as "make ARCH=arm64 install". Recently, the Kbuild tree queued up a patch to avoid needless compiler/linker flag evaluation. I beleive it is a good improvement itself, but causing a false-positive warning for arm64 installation in linux-next. (Thanks to Nathan for the report) Kconfig can test the linker capability just once, and store it in the .config file. The build and installation steps that follow do not need to test the liniker over again.

Please suggest a one if you have a better idea. arch/arm64/Kconfig | 3 +++ arch/arm64/Makefile | 2 +- 2 files changed, 4 insertions(+), 1 deletion(-)Would you like this patch to go in via the arm64 tree or you will queue it via the kbuild tree?
I applied this to linux-kbuild with Will's Ack. Thanks. -- Best Regards Masahiro Yamada _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
