I think it's really only *required* on platforms that use the regular 
uvm_fault() path to handle mod/ref emulation (and thus *MUST* seed that 
information when entering wired mappings).

But it would probably be a good idea to fix up all the callers anyway.  
If the underlying pmap doesn't do anything with the information, still 
no harm done.
