Hi Ard,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master head: 4853c74bd7ab7fdb83f319bd9ace8a08c031e9b6 commit: 9cf42bca30e98a1c6c9e8abf876940a551eaa3d1 efi: libstub: use EFI_LOADER_CODE region when moving the kernel in memory date: 9 months ago config: x86_64-rhel-8.3 (https://download.01.org/0day-ci/archive/20230817/202308172116.yPoBelLU-lkp@intel.com/config) compiler: gcc-12 (Debian 12.2.0-14) 12.2.0 reproduce: (https://download.01.org/0day-ci/archive/20230817/202308172116.yPoBelLU-lkp@intel.com/reproduce)
If you fix the issue in a separate patch/commit (i.e. not just a new version of the same patch/commit), kindly add following tags | Reported-by: kernel test robot <lkp@intel.com> | Closes: https://lore.kernel.org/oe-kbuild-all/202308172116.yPoBelLU-lkp@intel.com/
