Alan Cox 4d572bb3ed When vm_map_find(find_space = VMFS_OPTIMAL_SPACE) fails to find space, a
second scan of the address space with find_space = VMFS_ANY_SPACE is
performed.  Previously, vm_map_find() released and reacquired the map lock
between the first and second scans.  However, there is no compelling
reason to do so.  This revision modifies vm_map_find() to retain the map
lock.
