Patch 1 -> 6 applied for next, with some minor updates to patch2.

Patch 7 needs some more work, I will comment on that separately.

I am okay with patch 8 -> 22, but since there will be a re-spin for a
new version, perhaps you can run a new round of checkpatch.pl to see
if some of the warning that it reports can be fixed too.
