A quick reading of the offending patch seems to indicate that it is
just a buffer extension in preparation for future hardware support,
i.e. all that the new code seems to do is to set the added field to 0,
in addition to adding some compat code for versioning.  Given that
we're not going to have the future hardware support in 2.20 (slushy
freeze and all), maybe we should push this to 2.21 and fix the ABI in
2.20.

Unless of course, it is evident that there is absolutely no way to
introduce the new hardware support that Andreas alluded to without
breaking ABI...
