In linux kernel since version 3.16 (release Date: 2014-08-03)  
IBM s/390 and zSeries machines running under z/VM 5.1 or later
provide a virtual watchdog timer to their guest that cause a
user define Control Program command to be executed after a
timeout.
LPAR provides a very similar interface. This driver handles
both.

To compile this driver as a module, choose M here. The module
will be called diag288_wdt.
