  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.

  96config 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.
