Your get_pgd_slow patch looks good to me. Yes, it slightly increases the assumptions here about what is done in common, to the extent of a pmd_populate, but even the nr_page_table_pages adjustment just nicely balances what you were already having to do in free_pgd_slow. Sorry for dumping you suddenly into this with my BUG_ON(mm->nr_ptes), but I think we all agree it's a worthwhile check now. And sorry for being so slow to respond, but I needed to think through what's right for your case. I'll write separately about Nick's FIRST_USER_ADDRESS patch, I'm still puzzled, and not quite happy with that one.
