Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma updates from Doug Ledford: "Initial roundup of 4.5 merge window patches - Remove usage of ib_query_device and instead store attributes in ib_device struct - Move iopoll out of block and into lib, rename to irqpoll, and use in several places in the rdma stack as our new completion queue polling library mechanism. Update the other block drivers that already used iopoll to use the new mechanism too. - Replace the per-entry GID table locks with a single GID table lock - IPoIB multicast cleanup - Cleanups to the IB MR facility - Add support for 64bit extended IB counters - Fix for netlink oops while parsing RDMA nl messages - RoCEv2 support for the core IB code - mlx4 RoCEv2 support - mlx5 RoCEv2 support - Cross Channel support for mlx5 - Timestamp support for mlx5 - Atomic support for mlx5 - Raw QP support for mlx5 - MAINTAINERS update for mlx4/mlx5 - Misc ocrdma, qib, nes, usNIC, cxgb3, cxgb4, mlx4, mlx5 updates - Add support for remote invalidate to the iSER driver (pushed through the RDMA tree due to dependencies, acknowledged by nab) - Update to NFSoRDMA (pushed through the RDMA tree due to dependencies, acknowledged by Bruce)" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (169 commits) IB/mlx5: Unify CQ create flags check IB/mlx5: Expose Raw Packet QP to user space consumers {IB, net}/mlx5: Move the modify QP operation table to mlx5_ib IB/mlx5: Support setting Ethernet priority for Raw Packet QPs IB/mlx5: Add Raw Packet QP query functionality IB/mlx5: Add create and destroy functionality for Raw Packet QP IB/mlx5: Refactor mlx5_ib_qp to accommodate other QP types IB/mlx5: Allocate a Transport Domain for each ucontext net/mlx5_core: Warn on unsupported events of QP/RQ/SQ net/mlx5_core: Add RQ and SQ event handling net/mlx5_core: Export transport objects IB/mlx5: Expose CQE version to user-space IB/mlx5: Add CQE version 1 support to user QPs and SRQs IB/mlx5: Fix data validation in mlx5_ib_alloc_ucontext IB/sa: Fix netlink local service GFP crash IB/srpt: Remove redundant wc array IB/qib: Improve ipoib UD performance IB/mlx4: Advertise RoCE v2 support IB/mlx4: Create and use another QP1 for RoCEv2 IB/mlx4: Enable send of RoCE QP1 packets with IP/UDP headers ...
