SaveInstanceState of RecyclerView

this is my data

List<ItemData> data = new ArrayList<>();

LinearLayoutManager llm = new LinearLayoutManager(this);
MyAdapter mAdapter;
RecyclerView recyclerView;

and this is my recycler view in OnCreate method

recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(llm);
llm.setStackFromEnd(true);
mAdapter = new MyAdapter(data, getApplication());
recyclerView.setAdapter(mAdapter);
recyclerView.setItemAnimator(new DefaultItemAnimator());

how can i use onSaveInstanceState and onRestoreInstanceState to save my data list so doesn't dissapear in rotation?

    android:configChanges="orientation|screenSize"
