Pull rdma updates from Jason Gunthorpe: - Various minor code cleanups and fixes for hns, iser, cxgb4, hfi1, rxe, erdma, mana_ib - Prefetch supprot for rxe ODP - Remove memory window support from hns as new device FW is no longer support it - Remove qib, it is very old and obsolete now, Cornelis wishes to restructure the hfi1/qib shared layer - Fix a race in destroying CQs where we can still end up with work running because the work is cancled before the driver stops triggering it - Improve interaction with namespaces: * Follow the devlink namespace for newly spawned RDMA devices * Create iopoib net devces in the parent IB device's namespace * Allow CAP_NET_RAW checks to pass in user namespaces - A new flow control scheme for IB MADs to try and avoid queue overflows in the network - Fix 2G message sizes in bnxt_re - Optimize mkey layout for mlx5 DMABUF - New "DMA Handle" concept to allow controlling PCI TPH and steering tags * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (71 commits) RDMA/siw: Change maintainer email address RDMA/mana_ib: add support of multiple ports RDMA/mlx5: Refactor optional counters steering code RDMA/mlx5: Add DMAH support for reg_user_mr/reg_user_dmabuf_mr IB: Extend UVERBS_METHOD_REG_MR to get DMAH RDMA/mlx5: Add DMAH object support RDMA/core: Introduce a DMAH object and its alloc/free APIs IB/core: Add UVERBS_METHOD_REG_MR on the MR object net/mlx5: Add support for device steering tag net/mlx5: Expose IFC bits for TPH PCI/TPH: Expose pcie_tph_get_st_table_size() RDMA/mlx5: Fix incorrect MKEY masking RDMA/mlx5: Fix returned type from _mlx5r_umr_zap_mkey() RDMA/mlx5: remove redundant check on err on return expression RDMA/mana_ib: add additional port counters RDMA/mana_ib: Fix DSCP value in modify QP RDMA/efa: Add CQ with external memory support RDMA/core: Add umem "is_contiguous" and "start_dma_addr" helpers RDMA/uverbs: Add a common way to create CQ with umem RDMA/mlx5: Optimize DMABUF mkey page size ...
