Hi Ard,

kernel test robot noticed the following build errors:

Hmm it seems I missed some things in link-vmlinux.sh - I will take a look.

I will insert this before you patch set.
https://lore.kernel.org/linux-kbuild/20250313102604.1491732-1-masahiroy@kernel.org/T/#u

I would have done this earlier.
That is simply because I always run out of my time
and I do not have time to fix issues before someone stumbles on them.

Building linux-next breaks on s390 with DEBUG_INFO_BTF enabled because
of this; just where your addon patch ends:

  LD      vmlinux.unstripped
  BTFIDS  vmlinux
FAILED cannot open vmlinux: No such file or directory
make[2]: *** [scripts/Makefile.vmlinux:91: vmlinux.unstripped] Error 255

make[1]: *** [/home/builder/linux-next/Makefile:1239: vmlinux] Error 2
make: *** [Makefile:248: __sub-make] Error 2

I guess _something_ like below is needed to fix this (works for
me(tm)):
