    sys/sparc64/sparc64  exception.S interrupt.S 
  Log:
  MFC: sys/sparc64/sparc64/exception.S 1.73,
       sys/sparc64/sparc64/interrupt.S 1.9
  
  - In intr_fast() fix a race which is fallout from critical sections no longer
    raising the PIL and can cause corruption of the interrupt request lists.
  - In intr_fast() assert that the ir_func to be called is non-zero.
  - Increment interrupt stats after calling the handlers rather than before in
    order to reduce the delay until direct and fast handlers are serviced.
