Hi Nathan,

First bad commit (maybe != root cause):

tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
head: 692b7dc87ca6d55ab254f8259e6f970171dc9d01
commit: 5eb6e280432ddc9b755193552f3a070da8d7455c ARM: 9289/1: Allow pre-ARMv5 builds with ld.lld 16.0.0 and newer
date: 5 months ago
config: arm-neponset_defconfig (https://download.01.org/0day-ci/archive/20230620/202306201322.xTUPn7A1-lkp@xxxxxxxxx/config)
compiler: clang version 16.0.4 (https://github.com/llvm/llvm-project.git ae42196bc493ffe877a7e3dff8be32035dea4d07)
reproduce: (https://download.01.org/0day-ci/archive/20230620/202306201322.xTUPn7A1-lkp@xxxxxxxxx/reproduce)

the same patch/commit), kindly add following tags
