Here's my attempt to fix the issue.

Not sure if tricks with padding in a good idea. We can  just use __u64
instead of pointer, but it will require update of userspace to silence
cast warning and will cause warning if you will try to use updated
userspace with old kernel headers.

Any comments?

This does not fix anything really, we simply have to deal with compat
interface.

Compiled but not tested.

Thanks.

Sorry for late response, I have been extremely busy doing some skiing :-)

Thanks a lot for fixing this embarassing bug, Dmitry. I have now applied 
the patch.
