uvm amaps got restructured that way for 6.0. What you are seeing is in
a different part of uvm.
>From uvm_mapent_alloc in sys/uvm/uvm_map.c: Looks like the allocation
succeeds, but your system is allocating map entries at a too high rate.
Can't tell why that is though.
if (map->flags & VM_MAP_INTRSAFE || cold) {
mtx_enter(&uvm_kmapent_mtx);
if (SLIST_EMPTY(&uvm.kentry_free)) {
ne = km_alloc(PAGE_SIZE, &kv_page, &kp_dirty,
&kd_nowait);
if (ne == NULL)
panic("uvm_mapent_alloc: cannot allocate map "
"entry");
for (i = 0; i < PAGE_SIZE / sizeof(*ne); i++) {
SLIST_INSERT_HEAD(&uvm.kentry_free,
&ne[i], daddrs.addr_kentry);
}
if (ratecheck(&uvm_kmapent_last_warn_time,
&uvm_kmapent_warn_rate))
printf("uvm_mapent_alloc: out of static "
"map entries\n");
}
me = SLIST_FIRST(&uvm.kentry_free);
SLIST_REMOVE_HEAD(&uvm.kentry_free, daddrs.addr_kentry);
uvmexp.kmapent++;
mtx_leave(&uvm_kmapent_mtx);
me->flags = UVM_MAP_STATIC;
