docs/mm: expand vma doc to highlight pte freeing, non-vma traversal
The process addresses documentation already contains a great deal of
information about mmap/VMA locking and page table traversal and
manipulation.
However it waves it hands about non-VMA traversal. Add a section for this
and explain the caveats around this kind of traversal.
Additionally, commit 6375e95f381e ("mm: pgtable: reclaim empty PTE page in
madvise(MADV_DONTNEED)") caused zapping to also free empty PTE page
tables. Highlight this.
