Paolo, can you hold off on queuing this patch?  Long story short, this jogged my
memory for something tangentially related and I ended up with series that kills
off __ex() / ____kvm_handle_fault_on_reboot() completely.  It's coded up, I just
need to test.  I'm OOO for a few days, will hopefully get it posted next week.

Thanks!
