  Log:
  Don't use fuword() and suword() on struct members of type int. This
  happens to work on 32-bit platforms as sizeof(long)=sizeof(int), but
  wrecks all kinds of havoc (garbage reads, corrupting writes and
  misaligned loads/stores) on 64-bit architectures.
  The fix for now is to use fuword32() and suword32() and change the
  type of the applicable int fields to int32. This is to make it
  explicit that we depend on these fields being 32-bit. We may want
  to revisit this later.
