  76           By enabling this you make sure that the watchdog does not bite while
  77           printing oopses. Recommended for development systems but not for
  78           production releases.

  83          This options enables the API to a fast timer implementation using
  84          timer1 to get sub jiffie resolution timers (primarily one-shot
  85          timers).
  86          This is needed if CONFIG_ETRAX_SERIAL_FAST_TIMER is enabled.

  88 config PREEMPT
  89         bool "Preemptible Kernel"
  90         help
  91           This option reduces the latency of the kernel when reacting to
  92           real-time or interactive events by allowing a low priority process to
  93           be preempted even if it is in kernel mode executing a system call.
  94           This allows applications to run more reliably even when the system is
  95           under load.
  96
  97           Say Y here if you are building a kernel for a desktop, embedded
  98           or real-time system.  Say N if you are unsure.
