From d4faf5a948c03ffe61b4bfd1ebcdc93343727ca4 Mon Sep 17 00:00:00 2001 From: Andrew Cooper Date: Thu, 8 Mar 2012 09:23:27 +0000 Subject: NMI: Command line parameter for watchdog timeout Introduce a command parameter to set the watchtog timeout. Manually specifying "watchdog_timeout=" on the command line will also turn the watchdog on. For consistency, move opt_watchdog into nmi.c along with opt_watchdog_timeout.
