491 help
492 Switches the regular HZ timer off when the system is going idle.
493 This helps z/VM to detect that the Linux system is idle. VM can
494 then "swap-out" this guest which reduces memory usage. It also
495 reduces the overhead of idle systems.
496
497 The HZ timer can be switched on/off via /proc/sys/kernel/hz_timer.
498 hz_timer=0 means HZ timer is disabled. hz_timer=1 means HZ
499 timer is active.

506 HZ timer is already disabled at boot time.
