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