Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "This contains a replacement driver for Intel iWarp hardware. This new driver supports the old ethernet hardware and also newer chips that can do ROCE. Other than that, this contains the typical mix of patches: - Driver updates and cleanups for bnxt_re, cxgb4, mlx4, and mlx5 - Many static checker driven code clean ups, including a wide refcount_t conversion - Several series for the hns driver, more HIP09 HW capabilities, migration to new HW register manipulators, and code cleanups - Minor fixes and improvements in srp, rts, and cm - Improvements throughout for sysfs related code to use DEVICE_ATTR_*, make the ib_port sysfs first-class, and overall use sysfs APIs properly - Intel's new irdma driver replacing i40iw - rxe general clean ups and Memory Window support" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (211 commits) RDMA/core: Always release restrack object RDMA/mlx5: Don't access NULL-cleared mpi pointer RDMA/irdma: Fix potential overflow expression in irdma_prm_get_pbles RDMA/irdma: Check contents of user-space irdma_mem_reg_req object RDMA/rxe: Missing unlock on error in get_srq_wqe() RDMA/cma: Fix rdma_resolve_route() memory leak RDMA/core/sa_query: Remove unused argument RDMA/cma: Fix incorrect Packet Lifetime calculation RDMA/cma: Protect RMW with qp_mutex RDMA/cma: Remove unnecessary INIT->INIT transition RDMA/hns: Add window selection field of congestion control RDMA/hfi1: Remove use of kmap() RDMA/irdma: Remove use of kmap() RDMA/bnxt_re: Fix uninitialized struct bit field rsvd1 IB/isert: Align target max I/O size to initiator size RDMA/hns: Fix incorrect vlan enable bit in QPC MAINTAINERS: Update Broadcom RDMA maintainers RDMA/irdma: Use the queried port attributes RDMA/rxe: Fix redundant skb_put_zero RDMA/rxe: Fix extra copy in prepare_ack_packet ...
