79  * virtual address space that is mapped by a submap is locked by the
80  * submap's lock -- not the kernel_map's lock.
92  * The kmem_arena is a "special submap", as it lives in a fixed map entry
106  * object mapped into that range (e.g. a vnode).    for submap's kernel
108  * offsets that are managed by the submap.
