Следующим образом:

  config NO_HZ
	  bool "Old Idle dynticks config"
	  help
	    This is the old config entry that enables dynticks idle.
	    We keep it around for a little while to enforce backward
	    compatibility with older config files.

Фраща "old". Плюс фраза "old obsolete dynticks idle symbol" в коммите,
который добавляет этот текст:

  commit 0644ca5c774f1a7033bfc83c7ed0660f74f28b56
  AuthorDate: Fri Apr 12 16:40:12 2013 +0200

      Namely we want:

	      config NO_HZ # old obsolete dynticks idle symbol
		      bool

	      config NO_HZ_IDLE # new dynticks idle symbol
		      default NO_HZ


Я так же не нахожу в коде использования CONFIG_NO_HZ.

(ps. У меня на defconfig она оказалась =y, но сейчас я его перегенерировал и
она стала =y. Значит тут я ошибся.)
