I noticed one other significant gotcha with my changes.

Code that has not been converted and needs to be converted fails to
build with type errors.  -- Good.

Code that has not been converted and needs to be converted is still
selectable in make config.  -- Bad

make oldmodconfig -- fails with type errors unless everything is
converted Bad.

So I am adding/debugging an additional patch that will catch these
failure in Kconfig so people don't get nasty surprises.
