Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull more rdma updates from Jason Gunthorpe: "This is the SMC cleanup promised, a randconfig regression fix, and kernel oops fix. Summary: - Switch SMC over to rdma_get_gid_attr and remove the compat - Fix a crash in HFI1 with some BIOS's - Fix a randconfig failure" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: IB/ucm: fix UCM link error IB/hfi1: Invalid NUMA node information can cause a divide by zero RDMA/smc: Replace ib_query_gid with rdma_get_gid_attr
