Use preempt_model_str() instead of manually conducting the preemption
model. Use pr_emerg() instead of printk() to pass a loglevel.
Why use pr_emerg() for that line and not all other ones ?
The purpose of using printk() is to get it at the level defined by
CONFIG_MESSAGE_LOGLEVEL_DEFAULT and I think it is important to have the
full Oops block at the same level.
