Additionally, further discussions around this new uverb seems to conclude it would require a different data structure than the one currently described in [3]. Both of these issues require a revert of the changes, so this patch partially reverts commit 8cdd312cfed7 ("IB/mlx5: Implement the ODP capability query verb") and commit 860f10a799c8 ("IB/core: Add flags for on demand paging support") and fully reverts commit 5a77abf9a97a ("IB/core: Add support for extended query device caps").
