I think this commit required for 10-STABLE too:

op at opn hardenedBSD.git> git grep "vm pagequeue"
sys/vm/vm_page.c:               mtx_init(&pq->pq_mutex, pq->pq_name,
"vm pagequeue",
op at opn hardenedBSD.git> git grep "vm page queue"
sys/kern/subr_witness.c:        { "vm page queue", &lock_class_mtx_sleep },
sys/kern/subr_witness.c:        { "vm page queue", &lock_class_mtx_sleep },
op at opn hardenedBSD.git>

It would be nice to MFC them to 10-STABLE too.
