This allows you to specify the maximum number of CPUs which this
kernel will support. The maximum supported value is 64 and the
can be controlled through /sys/devices/system/cpu/cpu#.
Say N if you want to disable CPU hotplug.

This driver provides the Queued Direct I/O base support for
- IBM mainframes.

- For details please refer to the documentation provided by IBM at
- <http://www10.software.ibm.com/developerworks/opensource/linux390>
+ IBM System z.
To compile this driver as a module, choose M here: the
module will be called qdio.

-config PREEMPT
- bool "Preemptible Kernel"
- help
- This option reduces the latency of the kernel when reacting to
- real-time or interactive events by allowing a low priority process to
- be preempted even if it is in kernel mode executing a system call.
- This allows applications to run more reliably even when the system is
- under load.

- Say N if you are unsure.

Select this option, if you want to share the text segment of the
Linux kernel between different VM guests. This reduces memory
usage with lots of guests but greatly increases kernel size.
+ Also if a kernel was IPL'ed from a shared segment the kexec system
+ call will not work.
You should only select this option if you know what you are
doing and want to exploit this feature.
Select this option to enable the special message interface to
the cooperative memory management.

-config NO_IDLE_HZ

- help
- 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
- timer is active.
-
-config NO_IDLE_HZ_INIT
- bool "HZ timer in idle off by default"
- depends on NO_IDLE_HZ
- help
- The HZ timer is switched off in idle by default. That means the
