Are all the ports using the new gcc? If I may, I would like to use C99's
variadic macros to implement two-argument KASSERT. For example,

  void     __assert1(const char *, const char *, int, const char *)
              __attribute__((__noreturn__));
  
  void     __assert(const char *, const char *, int, const char *, ...)
              __attribute__((__noreturn__));
  
  #define KASSERT1(e)                                             \
          (__predict_true((e)) ? (void)0 :                        \
              __assert1("diagnostic ", __FILE__, __LINE__, #e))
  
  #define KASSERT(e, ...)                                         \
          (__predict_true((e)) ? (void)0 :                        \
              __assert("diagnostic ", __FILE__, __LINE__, __VA_ARGS__))

Example invocation,

  KASSERT(nseg <= ATH_MAX_SCATTER,
          "ath_mbuf_load_cb: too many DMA segments %u", nseg);
