This driver adds support for systems with ACPI Watchdog Action
Table (WDAT) table. Servers typically have this but it can be
found on some desktop machines as well. This driver will take
over the native iTCO watchdog driver found on many Intel CPUs.

To compile this driver as module, choose M here: the module will
be called wdat_wdt.
