[PATCH] Allow panics and reboots at oops time.
From: Russell Miller <rmiller@duskglow.com>
A BUG or an oops will often leave a machine in a useless state. There is no
way to remotely recover the machine from that state.
The patch adds a /proc/sys/kernel/panic_on_oops sysctl which, when set, will
cause the x86 kernel to call panic() at the end of the oops handler. If the
user has also set /proc/sys/kernel/panic then a reboot will occur.
The implementation will try to sleep for a while before panicing so the oops
info has a chance of hitting the logs.
The implementation is designed so that other architectures can easily do this
in their oops handlers.
