Subject: linux-next: build failure after merge of the execve tree

Hi all,

After merging the execve tree, today's linux-next build (x86_64
allmodconfig) failed like this:

fs/binfmt_elf.c: In function 'load_elf_library':
fs/binfmt_elf.c:1323:37: error: unused variable 'len' [-Werror=unused-variable]
 1323 |         unsigned long elf_bss, bss, len;
      |                                     ^~~
fs/binfmt_elf.c:1323:32: error: unused variable 'bss' [-Werror=unused-variable]
 1323 |         unsigned long elf_bss, bss, len;
      |                                ^~~
fs/binfmt_elf.c:1323:23: error: unused variable 'elf_bss' [-Werror=unused-variable]
 1323 |         unsigned long elf_bss, bss, len;
      |                       ^~~~~~~
cc1: all warnings being treated as errors

Caused by commit

  f2a1e5fab9ae ("binfmt_elf: Use elf_load() for library")

I have used the execve tree from next-20230929 for today.
