Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma
Pull rdma updates from Doug Ledford: "This is my initial round of 4.4 merge window patches. There are a few other things I wish to get in for 4.4 that aren't in this pull, as this represents what has gone through merge/build/run testing and not what is the last few items for which testing is not yet complete. - "Checksum offload support in user space" enablement - Misc cxgb4 fixes, add T6 support - Misc usnic fixes - 32 bit build warning fixes - Misc ocrdma fixes - Multicast loopback prevention extension - Extend the GID cache to store and return attributes of GIDs - Misc iSER updates - iSER clustering update - Network NameSpace support for rdma CM - Work Request cleanup series - New Memory Registration API" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (76 commits) IB/core, cma: Make __attribute_const__ declarations sparse-friendly IB/core: Remove old fast registration API IB/ipath: Remove fast registration from the code IB/hfi1: Remove fast registration from the code RDMA/nes: Remove old FRWR API IB/qib: Remove old FRWR API iw_cxgb4: Remove old FRWR API RDMA/cxgb3: Remove old FRWR API RDMA/ocrdma: Remove old FRWR API IB/mlx4: Remove old FRWR API support IB/mlx5: Remove old FRWR API support IB/srp: Dont allocate a page vector when using fast_reg IB/srp: Remove srp_finish_mapping IB/srp: Convert to new registration API IB/srp: Split srp_map_sg RDS/IW: Convert to new memory registration API svcrdma: Port to new memory registration API xprtrdma: Port to new memory registration API iser-target: Port to new memory registration API IB/iser: Port to new fast registration API ...
