Revision f172ddc61ad7a7c444b2b3e08992a45c76b821f9 authored by Chen Gong on 29 April 2008, 08:42:05 UTC, committed by Wim Van Sebroeck on 25 May 2008, 09:43:06 UTC
On Book-E SMP systems each core has its own private watchdog.  If only one
watchdog is enabled, when the core that doesn't enable the watchdog is hung,
system can't reset because no watchdog is running on it.  That's bad.  It
means we must enable watchdogs on both cores.

We can use smp_call_function() to send appropriate messages to all the other
cores to enable and update the watchdog.
