I'd imagine ssi_rcopy_in_user() would...

1. If both dst & src are local just call local copy_in_user() and we are done.
2. If dst is remote do ssi_rcopy_to_user()
3. If src is remote do ssi_rcopy_from_user()

Currently we do nothing special for this, so the default implementation:

   for (i = 1; i < len; ++i) {
      copy_from_user (from[i]);
      copy_to_user (to[i]);
   }

will be used.

Pretty non-optimal if the user process is on another node!
