Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "Aside from the usual things this has an arch update for __iowrite64_copy() used by the RDMA drivers. This API was intended to generate large 64 byte MemWr TLPs on PCI. These days most processors had done this by just repeating writel() in a loop. S390 and some new ARM64 designs require a special helper to get this to generate. - Small improvements and fixes for erdma, efa, hfi1, bnxt_re - Fix a UAF crash after module unload on leaking restrack entry - Continue adding full RDMA support in mana with support for EQs, GID's and CQs - Improvements to the mkey cache in mlx5 - DSCP traffic class support in hns and several bug fixes - Cap the maximum number of MADs in the receive queue to avoid OOM - Another batch of rxe bug fixes from large scale testing - __iowrite64_copy() optimizations for write combining MMIO memory - Remove NULL checks before dev_put/hold() - EFA support for receive with immediate - Fix a recent memleaking regression in a cma error path" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (70 commits) RDMA/cma: Fix kmemleak in rdma_core observed during blktests nvme/rdma use siw RDMA/IPoIB: Fix format truncation compilation errors bnxt_re: avoid shift undefined behavior in bnxt_qplib_alloc_init_hwq RDMA/efa: Support QP with unsolicited write w/ imm. receive IB/hfi1: Remove generic .ndo_get_stats64 IB/hfi1: Do not use custom stat allocator RDMA/hfi1: Use RMW accessors for changing LNKCTL2 RDMA/mana_ib: implement uapi for creation of rnic cq RDMA/mana_ib: boundary check before installing cq callbacks RDMA/mana_ib: introduce a helper to remove cq callbacks RDMA/mana_ib: create and destroy RNIC cqs RDMA/mana_ib: create EQs for RNIC CQs RDMA/core: Remove NULL check before dev_{put, hold} RDMA/ipoib: Remove NULL check before dev_{put, hold} RDMA/mlx5: Remove NULL check before dev_{put, hold} RDMA/mlx5: Track DCT, DCI and REG_UMR QPs as diver_detail resources.
