  84           By enabling this you make sure that the watchdog does not bite while
  85           printing oopses. Recommended for development systems but not for
  86           production releases.

  91          This options enables the API to a fast timer implementation using
  92          timer1 to get sub jiffie resolution timers (primarily one-shot
  93          timers).
  94          This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.

  96 config PREEMPT
  97         bool "Preemptible Kernel"
  98         help
  99           This option reduces the latency of the kernel when reacting to
 100           real-time or interactive events by allowing a low priority process to
 101           be preempted even if it is in kernel mode executing a system call.
 102           This allows applications to run more reliably even when the system is
 103           under load.
 104
 105           Say Y here if you are building a kernel for a desktop, embedded
 106           or real-time system.  Say N if you are unsure.
