Putting a few bytes ahead of page tables isn't very efficient; there's
a gap almost worth a full page. To avoid re-ordering of items in the
source file, simply put the few small items in sub-section 1, for them
to end up after the page tables, followed (in the final binary) by non-
page-aligned items from other CUs.
