Especially the "For PROT_NONE VMAs, the PTEs are not marked _PAGE_PROTNONE" is wrong: doing an mprotect(PROT_NONE) will end up marking all PTEs on x86 as _PAGE_PROTNONE, making pte_protnone() indicate "yes".
So let's improve the comment, so it's easier to grasp which semantics pte_protnone() actually has.
