The RDMA related patches have been applied to the RDMA tree on a
shared topic branch, so I've merged that into hmm.git and applied the
last patches from this series on top:

There was some conflict churn in the RDMA ODP patches vs what was used
to the patches from this series, I fixed it up. Now I'm waiting for
some testing feedback before pushing it to linux-next

Thanks,
