-          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.
-          Unfortunately the kernel code has some race conditions if both
-          CONFIG_SMP and CONFIG_PREEMPT are enabled, so this option is
-          currently disabled if you are building an SMP kernel.

-          Say Y here if you are building a kernel for a desktop, embedded
-          or real-time system.  Say N if you are unsure.
