The patch didn't end up mangled on my side but definitely did not
cleared checkpatch, which may indicate some sort of problem with the
email client (as I assume you did indeed run checkpatch.sh).
It would also be a good idea to update the TODO file to reflect that
some of the macros have now been moved to a header file.
I will review the work when checkpatch is happy.
Thanks,
Mathieu
