Well, we still have that printk string in there.

And that is incorrect too, because the MCE (at least the one I'm
injecting) gets broadcasted to the CPUs on the *node* and not to the
whole system.

If we had to be precise, text should say "Not all CPUs which the MCE was
broadcasted to entered the exception handler..."
