I did both pte_dirty and pte_write because I was extra careful. One _should_ imply the other, but since we'll be clearing both, I thought it prudent to also check both.
I will have to think on this a little more, but I'm currently of the opinion that the optimisation is not correct. But I'll have a thorough look at s390 again when I get home.
