Again, as I said last time, it is not worth adding 
'loongson,parent-int-map' and having to support both forms in the kernel 
forever. If you can define a time that we keep 'loongson,parent_int_map' 
that's less than "forever", then may be it would be worth changing.

To put this another way, using '-' instead of '_' is for *new* bindings, 
not existing users.
