Send and Receive completion is handled on a single CPU selected at the time each Completion Queue is allocated. Typically this is when an initiator instantiates an RDMA transport, or when a target accepts an RDMA connection. Some ULPs cannot open a connection per CPU to spread completion workload across available CPUs and MSI vectors. For such ULPs, provide an API that allows the RDMA core to select a completion vector based on the device's complement of available comp_vecs. ULPs that invoke ib_alloc_cq() with only comp_vector 0 are converted to use the new API so that their completion workloads interfere less with each other. Suggested-by:

The device requires that memory registration work requests that update the address translation table of a MR will be fenced if posted together. This scenario can happen when address ranges are invalidated by the mmu in separate concurrent calls to the invalidation callback. We prefer to block concurrent address updates for a single MR over fencing since making the decision if a WQE needs fencing will be more expensive and fencing all WQEs is a too radical choice. Further, it isn't clear that this code can even run safely concurrently, so a lock is a safer choice.

Fix unreg_umr to move the MR to a kernel owned PD (i.e. the UMR PD) which can't be accessed by userspace. This ensures that nothing can continue to access the MR once it has been placed in the kernels cache for reuse. MRs in the cache continue to have their HW state, including DMA tables, present. Even though the MR has been invalidated, changing the PD provides an additional layer of protection against use of the MR.
