I applied these patches to for-next

This might need some re-organizing - the last patch could be split
(possibly merge with the first) so the header changes can go to the
shared branch, but the handle_hca_cap_odp() stuff must only be applied
to the rdma tree.

I'm fine either way, if you don't want to split it send a commit ID
for the first patch on mlx5-next.

Thanks,
