I believe that Ingo was suggesting to have CONFIG_NO_HZ give options to what type of config NO_HZ you want. Something like:
config NO_HZ bool "Enable tickless support"
config NO_HZ_IDLE bool "Stop tick when CPU is idle" default y depends on NO_HZ
config NO_HZ_TASK bool "Stop tick on specified CPUs when single task is running" default n depends on NO_HZ
That is, if you select NO_HZ, by default NO_HZ_IDLE is also selected. But in the kernel the NO_HZ_IDLE is used.
