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/202505230141.4YBHhrPI-lkp@intel.com/
All errors (new ones prefixed by >>):

Hmm, this statement is under IS_ENABLED(CONFIG_X86_FRED), which should be a compile time FALSE with i386. Why it is still being compiled?
Thanks! Xin
