Unless I missed something in your first patch, I don't think this
series is bisectable, ie. replacing cpp w/ bpp would cause everything
else not to compile. Looks like there was an alternative proposal on
the first patch, but if we do end up going this route, I think you
should add bpp in the first patch, and remove cpp in the last patch.
(And also probably sprinkle around WARN_ON(info->bpp[n] % 8) in places
were it is expected to be a multiple of 8)
