I don't understand the question: `undo' is a normal editing operation,
just like any other, and smerge also doesn't do anything special about
the way it edits the buffer.  So they just interact in the obvious
and expected way.
The only thing that might be relevant is that if you resolve the last
conflict and turn off smerge-mode, undoing the last change won't
automatically turn smerge-mode back on.  It would be nice to improve
this, but it's really not that important.
