The patch just adds four new binary operations of the same order as the existing == and !=, with a the semantics that everybody expects. And the grammar for kconfig expressions is so simplistic that you cannot even write things like (A && B) == (C && D). So turing completeness is not a topic here, neither before nor after this patch.
