	  A software monitoring watchdog and NMI sourcing driver. This driver

	  will detect lockups and provide stack trace. Also, when an NMI

	  occurs this driver will make the necessary BIOS calls to log

	  the cause of the NMI. This is a driver that will only load on a

	  HP ProLiant system with a minimum of iLO2 support.

	  To compile this driver as a module, choose M here: the

	  module will be called hpwdt.

	help

	  Watchdog driver for the built in watchdog hardware in Sibyte

	  SoC processors.  There are apparently two watchdog timers

	  on such processors; this driver supports only the first one,

	  because currently Linux only supports exporting one watchdog

	  to userspace.

	  The module will be called sb_wdog.
