 config WATCHDOG
 	bool "Watchdog Timer Support"
 	---help---
 	  If you say Y here (and to one of the following options) and create a
 	  character special file /dev/watchdog with major number 10 and minor
 	  number 130 using mknod ("man mknod"), you will get a watchdog, i.e.:
 	  subsequently opening the file and then failing to write to it for
 	  longer than 1 minute will result in rebooting the machine. This
 	  could be useful for a networked machine that needs to come back
 	  online as fast as possible after a lock-up. There's both a watchdog
 	  implementation entirely in software (which can sometimes fail to
 	  reboot the machine) and a driver for hardware watchdog boards, which
 	  are more robust and can also keep track of the temperature inside
 	  your computer. For details, read <file:Documentation/watchdog/watchdog.txt>
 	  in the kernel source.

 	  The watchdog is usually used together with the watchdog daemon
 	  which is available from
 	  <ftp://ibiblio.org/pub/Linux/system/daemons/watchdog/>. This daemon can
 	  also monitor NFS connections and can reboot the machine when the process
 	  table is full.

 	  If unsure, say N.

 config WATCHDOG_NOWAYOUT
 	bool "Disable watchdog shutdown on close"
 	depends on WATCHDOG
 	help
 	  The default watchdog behaviour (which you get if you say N here) is
 	  to stop the timer if the process managing it closes the file
 	  /dev/watchdog. It's always remotely possible that this process might
 	  get killed. If you say Y here, the watchdog cannot be stopped once
 	  it has been started.

 	  Hardware driver for the TCO timer built into the Intel 82801
 	  I/O Controller Hub family.  The TCO (Total Cost of Ownership)
 	  timer is a watchdog timer that will reboot the machine after
 	  its second expiration. The expiration time can be configured
 	  with the "heartbeat" parameter.

 	  On some motherboards the driver may fail to reset the chipset's

	Hardware driver for the TCO timer built into the Intel 82801
	I/O Controller Hub family. The TCO (Total Cost of Ownership)
	timer is a watchdog timer that will reboot the machine after
	its second expiration. The expiration time can be configured
	with the "heartbeat" parameter.

	On some motherboards the driver may fail to reset the chipset's
	NO_REBOOT flag which prevents the watchdog from rebooting the
	machine. If this is the case you will get a kernel message like
	"failed to reset NO_REBOOT flag, reboot disabled by hardware".

	the watchdog. If you have a card that behave in similar ways,
	you can probably make this driver work with your card as well.

	This driver adds watchdog support for the integrated watchdog in the
	SuperH processors. If you have one of these processors and wish
	to have watchdog support enabled, say Y, otherwise say N.

	As a side note, saying Y here will automatically boost HZ to 1000
	so that the timer has a chance to clear the overflow counter. On
	slower systems (such as the SH-2 and SH-3) this will likely yield
	some performance issues. As such, the WDT should be avoided here
