badpage: KERN_ALERT BUG instead of KERN_EMERG
bad_page() and rmap Eeek messages have said KERN_EMERG for a few years, which I've followed in print_bad_pte(). These are serious system errors, on a par with BUGs, but they're not quite emergencies, and we do our best to carry on: say KERN_ALERT "BUG: " like the x86 oops does. And remove the "Trying to fix it up, but a reboot is needed" line: it's not untrue, but I hope the KERN_ALERT "BUG: " conveys as much.
