  Modified files:
    sys/sparc64/sparc64  intr_machdep.c 
  Log:
  Some changes to intr_execute_handlers():
  - Fix NULL pointer dereferences caused when an ithread or a handler is
    NULL which happens when a stray interrupt triggers after the respective
    device interrupt was torn down.
  - Remove the critical section around INTR_FAST handlers which actually
    was a nested critical section. Both tl0_intr() and tl1_intr() already
    enter a critical section for calling intr_execute_handlers().
