ARCH=arm64 build breakage for Kbuild for-next branch

ARCH=arm64 build breakage for Kbuild for-next branch

[Masahiro Yamada]

Hi Stephen,

If you pull the latest kbuild for-next branch,
ARCH=arm64 will fail to build.

I will fix it soon.

For today's linux-next, you can patch
as follows.
(or, you can use the old branch)


diff --git a/Makefile b/Makefile
index f80c4ff93ec9..fbb4b95ae648 100644
--- a/Makefile
+++ b/Makefile
@@ -1074,7 +1074,7 @@ build-dirs        := $(vmlinux-dirs)
 clean-dirs     := $(vmlinux-alldirs)

 # Externally visible symbols (used by link-vmlinux.sh)
-KBUILD_VMLINUX_OBJS := $(head-y) $(addsuffix built-in.a, $(core-y))
+KBUILD_VMLINUX_OBJS := $(head-y) $(patsubst %/,%/built-in.a, $(core-y))
 KBUILD_VMLINUX_OBJS += $(addsuffix built-in.a, $(filter %/, $(libs-y)))
 ifdef CONFIG_MODULES
 KBUILD_VMLINUX_OBJS += $(patsubst %/, %/lib.a, $(filter %/, $(libs-y)))


Thanks.

OK, thanks, I will apply that at some point, since I have already
merged your tree.

And then I forgot, sorry.  I assume it will be fixed tomorrow.
