demotion failure. Otherwise, some callers to pmap_demote_l2_locked(), such as pmap_protect(), may leave an incorrect mapping in place on a demotion failure. Change pmap_demote_l2_locked() so that it handles addresses that are not superpage aligned. Some callers to pmap_demote_l2_locked(), such as pmap_protect(), may not pass a superpage aligned address. Change pmap_enter_l2() so that it correctly calls vm_page_free_pages_toq(). The arm64 pmap is updating the count of wired pages when freeing page table pages, so pmap_enter_l2() should pass false to vm_page_free_pages_toq(). Optimize TLB invalidation in pmap_remove_l2().
