Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "A smaller cycle this time. Notably we see another new driver, 'Soft iWarp', and the deletion of an ancient unused driver for nes. - Revise and simplify the signature offload RDMA MR APIs - More progress on hoisting object allocation boiler plate code out of the drivers - Driver bug fixes and revisions for hns, hfi1, efa, cxgb4, qib, i40iw - Tree wide cleanups: struct_size, put_user_page, xarray, rst doc conversion - Removal of obsolete ib_ucm chardev and nes driver - netlink based discovery of chardevs and autoloading of the modules providing them - Move more of the rdamvt/hfi1 uapi to include/uapi/rdma - New driver 'siw' for software based iWarp running on top of netdev, much like rxe's software RoCE. - mlx5 feature to report events in their raw devx format to userspace - Expose per-object counters through rdma tool - Adaptive interrupt moderation for RDMA (DIM), sharing the DIM core from netdev" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (194 commits) RMDA/siw: Require a 64 bit arch RDMA/siw: Mark expected switch fall-throughs RDMA/core: Fix -Wunused-const-variable warnings rdma/siw: Remove set but not used variable 's' rdma/siw: Add missing dependencies on LIBCRC32C and DMA_VIRT_OPS RDMA/siw: Add missing rtnl_lock around access to ifa rdma/siw: Use proper enumerated type in map_cqe_status RDMA/siw: Remove unnecessary kthread create/destroy printouts IB/rdmavt: Fix variable shadowing issue in rvt_create_cq RDMA/core: Fix race when resolving IP address RDMA/core: Make rdma_counter.h compile stand alone IB/core: Work on the caller socket net namespace in nldev_newlink() RDMA/rxe: Fill in wc byte_len with IB_WC_RECV_RDMA_WITH_IMM RDMA/mlx5: Set RDMA DIM to be enabled by default RDMA/nldev: Added configuration of RDMA dynamic interrupt moderation to netlink RDMA/core: Provide RDMA DIM support for ULPs linux/dim: Implement RDMA adaptive moderation (DIM) IB/mlx5: Report correctly tag matching rendezvous capability docs: infiniband: add it to the driver-api bookset IB/mlx5: Implement VHCA tunnel mechanism in DEVX ...
