  Modified files:
    sys/i386/i386        swtch.s 
  Log:
  Use a critical region to protect saving of the npx state in savectx().
  Not doing this was fairly harmless because savectx() is only called
  for panic dumps and the bug could at worse reset the state.
  
  savectx() is still missing saving of (volatile) debug registers, and
  still isn't called for core dumps.
