o Add vm_map_wire() for wiring contiguous regions of either kernel
or user vm_maps. This implementation has two key benefits when compared to vm_map_{user_,}pageable(): (1) it avoids a race condition through the use of "in-transition" vm_map entries and (2) it eliminates lock recursion on the vm_map. Note: there is still an error case that requires clean up. Reviewed by: tegge
