"for in" is funky. And it's worth providing a brief explanation of what the
secondary pagetable stats actually are. "secondary" is confusingly close to
"second level pagetables", e.g. might be misconstrued as KVM counters for the
number of stage-2 / two-dimension paging page (TDP) tables.
Code looks good, though it needs a rebased on kvm/queue.
