Pull rdma fixes from Doug Ledford: "Round one of 4.8 rc fixes. This should be the bulk of the -rc fixes for 4.8. I only have a few things that are still outstanding (two ipoib bugs for which the solution is not yet fully known, and a few queued items that came in after my last push and I didn't want to delay this pull request for late comers again). Even though the patch count is kind of high, everything is minor fixes so the overall churn is pretty low. Summary: - minor fixes to cxgb4 - minor fixes to mlx4 - one minor fix each to core, rxe, isert, srpt, mlx5, ocrdma, and usnic - six or so fixes to i40iw fixes - the rest are hfi1 fixes" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma: (34 commits) i40iw: Send last streaming mode message for loopback connections IB/srpt: Update sport->port_guid with each port refresh RDMA/ocrdma: Fix the max_sge reported from FW i40iw: Avoid writing to freed memory i40iw: Fix double free of allocated_buffer IB/mlx5: Remove superfluous include of io-mapping.h i40iw: Do not set self-referencing pointer to NULL after kfree i40iw: Add missing NULL check for MPA private data iw_cxgb4: Fix cxgb4 arm CQ logic w/IB_CQ_REPORT_MISSED_EVENTS i40iw: Add missing check for interface already open i40iw: Protect req_resource_num update i40iw: Change mem_resources pointer to a u8 IB/core: Use memdup_user() rather than duplicating its implementation IB/qib: Use memdup_user() rather than duplicating its implementation iw_cxgb4: use the MPA initiator's IRD if < our ORD iw_cxgb4: limit IRD/ORD advertised to ULP by device max.
