Pull rdma updates from Jason Gunthorpe: "This has been a slightly more active cycle than normal with ongoing core changes and quite a lot of collected driver updates. - Various driver fixes for bnxt_re, cxgb4, hns, mlx5, pvrdma, rxe - A new data transfer mode for HFI1 giving higher performance - Significant functional and bug fix update to the mlx5 On-Demand-Paging MR feature - A chip hang reset recovery system for hns - Change mm->pinned_vm to an atomic64 - Update bnxt_re to support a new 57500 chip - A sane netlink 'rdma link add' method for creating rxe devices and fixing the various unregistration race conditions in rxe's unregister flow - Allow lookup up objects by an ID over netlink - Various reworking of the core to driver interface: - drivers should not assume umem SGLs are in PAGE_SIZE chunks - ucontext is accessed via udata not other means - start to make the core code responsible for object memory allocation - drivers should convert struct device to struct ib_device via a helper - drivers have more tools to avoid use after unregister problems" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (280 commits) net/mlx5: ODP support for XRC transport is not enabled by default in FW IB/hfi1: Close race condition on user context disable and close RDMA/umem: Revert broken 'off by one' fix RDMA/umem: minor bug fix in error handling path RDMA/hns: Use GFP_ATOMIC in hns_roce_v2_modify_qp cxgb4: kfree mhp after the debug print IB/rdmavt: Fix concurrency panics in QP post_send and modify to error IB/rdmavt: Fix loopback send with invalidate ordering IB/iser: Fix dma_nents type definition IB/mlx5: Set correct write permissions for implicit ODP MR bnxt_re: Clean cq for kernel consumers only RDMA/uverbs: Don't do double free of allocated PD RDMA: Handle ucontext allocations by IB/core RDMA/core: Fix a WARN() message bnxt_re: fix the regression due to changes in alloc_pbl IB/mlx4: Increase the timeout for CM cache IB/core: Abort page fault handler silently during owning process exit IB/mlx5: Validate correct PD before prefetch MR IB/mlx5: Protect against prefetch of invalid MR RDMA/uverbs: Store PR pointer before it is overwritten ...
