Now compilation prints a lot of wanings about redefined macro inside reiserfs and ceph.
Please pick also:
2f874deba7476a1e579af9028baa2f9dfdefedd1 ("conditionally define U32_MAX")
04f9b74e4d96d349de12fdd4e6626af4a9f75e09 ("remove extra definitions of U32_MAX")
without first second patch doesn't applies clearly
