Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull rdma updates from Jason Gunthorpe: "This is quite a small cycle, no major series stands out. The HNS and rxe drivers saw the most activity this cycle, with rxe being broken for a good chunk of time. The significant deleted line count is due to a SPDX cleanup series. Summary: - Various cleanup and small features for rtrs - kmap_local_page() conversions - Driver updates and fixes for: efa, rxe, mlx5, hfi1, qed, hns - Cache the IB subnet prefix - Rework how CRC is calcuated in rxe - Clean reference counting in iwpm's netlink - Pull object allocation and lifecycle for user QPs to the uverbs core code - Several small hns features and continued general code cleanups - Fix the scatterlist confusion of orig_nents/nents introduced in an earlier patch creating the append operation" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (90 commits) RDMA/mlx5: Relax DCS QP creation checks RDMA/hns: Delete unnecessary blank lines. RDMA/hns: Encapsulate the qp db as a function RDMA/hns: Adjust the order in which irq are requested and enabled RDMA/hns: Remove RST2RST error prints for hw v1 RDMA/hns: Remove dqpn filling when modify qp from Init to Init RDMA/hns: Fix QP's resp incomplete assignment RDMA/hns: Fix query destination qpn RDMA/hfi1: Convert to SPDX identifier IB/rdmavt: Convert to SPDX identifier RDMA/hns: Bugfix for incorrect association between dip_idx and dgid RDMA/hns: Bugfix for the missing assignment for dip_idx RDMA/hns: Bugfix for data type of dip_idx RDMA/hns: Fix incorrect lsn field RDMA/irdma: Remove the repeated declaration RDMA/core/sa_query: Retry SA queries RDMA: Use the sg_table directly and remove the opencoded version from umem lib/scatterlist: Fix wrong update of orig_nents lib/scatterlist: Provide a dedicated function to support table append RDMA/hns: Delete unused hns bitmap interface ...
