-# not in Kconfig) with this command:
-#
-# export LC_ALL=C LC_COLLATE=C
-# git grep CONFIG_ |tr ' \t' '\n\n' |sed -n 's/^\(CONFIG_[A-Z0-9_]*\).*/\1/p' \
-#	|sort |uniq >scripts/config_whitelist.txt;

+# Use scripts/build-whitelist.sh to generate the list of current ad-hoc
+# CONFIG options (those which are not in Kconfig).
