988 If kallsyms is not working correctly, the build will fail with
989 inconsistent kallsyms data. If that occurs, log a bug report and
990 turn on KALLSYMS_EXTRA_PASS which should result in a stable build.
991 Always say N here unless you find a bug in kallsyms, which must be
992 reported. KALLSYMS_EXTRA_PASS is only a temporary workaround while
993 you wait for kallsyms to be fixed.
