If ofed-1.5.1 is based on 2.6.33 then it will get this patch
automatically (assuming it goes upstream and makes 2.6.33). Or we can
pull it in as a kernel_patches/fixes/ patch.

My point, though, is that even with this patch in ofed-1.5.1, we still
have an openmpi/IB/rdmacm regression. The only way to avoid this
regression without changing openmpi is to disallow _all_ rdma binds to
127.0.0.1.
