The subject line is automatically generated, and uses whatever
subsystem prefix was most commonly used for all files touched in that
subsystem, while not containing any prefixes *not* so touched.

It's also automatically split up per-subsystem from a single big source
commit that changes everything at once. I can split this bit more
finely, but that means automated regeneration will be impossible, so
it'll probably backslide if I ever have to regenerate it -- and I've had
to regenerate this series a *lot*.

In fact if I'd split this bit per driver, I'd probably have
automatically got the subject line right as well -- but if the series as
a whole were split up like that, it'd have had about 400 patches rather
than 120, and got a lot of maintainers even more annoyed than they are
now.

For now, I'll split this one into four and mail it out again: coming
shortly.
