Subject: Split multi-line printk in oops output.

Sometimes, bug reports come in where we've had an oops, and the
only record we have is what the reporter saw on screen shortly
before the system locked up completely.  Unfortunatly, syslog
only prints lines beginning with KERN_EMERG to the console, so
some lines get lost.
An example of this can be seen at https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=203723

Some of this information isn't vital to diagnosis, but some parts
are useful, such as the tainted flag.
