Hi Masahiro,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master head: 21e80f3841c01aeaf32d7aee7bbc87b3db1aa0c6 commit: 3753af778dd9d0d5199d6a7d01b0ead33135d095 kbuild: fix single directory build date: 1 year, 1 month ago config: parisc-randconfig-002-20231102 (https://download.01.org/0day-ci/archive/20231103/202311030237.81SbvSC3-lkp@intel.com/config) compiler: hppa-linux-gcc (GCC) 13.2.0 reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20231103/202311030237.81SbvSC3-lkp@intel.com/reproduce)
