Heh, that was easy. Third hibernate cycle is a charm^Wboom :)

It looks like this way we mangle the anon_vma chains somehow. From
what I can see and if I'm not mistaken, we save the anon_vmas alright
but end up in what seems like an endless list_for_each_entry()
loop having grabbed anon_vma->lock in page_lock_anon_vma() and we
can't seem to yield it through page_unlock_anon_vma() at the end of
page_referenced_anon() so it has to be that code in between iterating
over each list entry...
I could be completely wrong though...
