Bring this code in line with the perf based generic NMI watchdog in kernel/watchdog.c (which we should convert over to at some point). In particular, don't do anything super fancy when the watchdog triggers, and specifically don't do a do_exit() which only makes things worse. Either panic(), or WARN(). The latter of which will do all of the actions such as give us a stack backtrace. Signed-off-by: David S. Miller <davem@davemloft.net>
