machines, but will use only one CPU of a multiprocessor machine. If

-config PREEMPT
- bool "Preemptible Kernel"
- help
- This option reduces the latency of the kernel when reacting 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.

- or real-time system. Say N if you are unsure.
