    sys/sun4v/include    pcb.h 
    sys/sparc64/sparc64  genassym.c 
  Log:
  - Explicitly name the fields in pcb that we use to store trap state for later
    retrieval, rather than using pad
  - save the fault address in sfar for use by the alignment fixup handler
  - mask off the trap number, so the context id doesn't confuse the UT_MAX
    comparison
  
  This change fixes alignment fixup handling which is needed for traceroute
  to work in spite of its copious unaligned accesses
