This bit of information is in the Kconfig help text:
Note the boot CPU will still be kept outside the range to handle the timekeeping duty.
However neither the variable NO_HZ_FULL_ALL, or the prompt convey this important detail, so lets add it to the prompt to make it more explicitly obvious to the average user.
