[PATCH] kprobes exception notifier fix
This patch modifies the return value of kprobes exceptions notify handler.
The kprobes exception notifier returns NOTIFY_STOP on handling
notification. This patch helps other debuggers to co-exists with the
Kprobes. Other debuggers registered for exceptions notification must
return NOTIFY_STOP on handling the notification.
