Log: Exploit r288122 to address a cosmetic issue. Pages belonging to either the kernel or kmem object can't be paged out. Since they can't be paged out, they are never enqueued in a paging queue. Nonetheless, passing PQ_INACTIVE to vm_page_unwire() in kmem_unback() creates the appearance that these pages are being enqueued in the inactive queue. As of r288122, we can avoid giving this false impression by passing PQ_NONE.
