The subject on all 4 of these need to be modified. Only the first line will be 
shown as the "subject", which will not make much sense.

In addition, you need to include the changes in the cover letter, and in the 
actual patch after the --- line. In that section, you mention what changes were 
made in each revision, then follow with another --- line. That info is there for 
the maintainers - it will be stripped before the patch is merged.
