      RDMA/cxgb3: fail get_dma_mr on 64 bit arches · 49fa63d8
      由 Steve Wise 提交于 
      T3 HW only supports 32 bit MRs.  If the system uses 64 bit memory
addresses, then a registered 32 bit MR will wrap and write to the
wrong memory when used with addresses > 4GB.  To prevent this,
simply fail to allocate an MR on 64 bit machines (other means
of registering memory are still available and software can still
work, we just don't allow this means of memory registration).

      IB/mlx4: Optimize do_slave_init · d9a047ae
      由 Doug Ledford 提交于 
      There is little chance our memory allocation will fail, so we can
combine initializing the work structs with allocating them instead of
looping through all of them once to allocate and again to initialize.
Then when we need to actually find out if our device is up or in the
process of going down, have all of our work structs batched up, take the
spin_lock once and only once, and do all of the batch under the one
spin_lock invocation instead of incurring all of the locked memory cycles
we would otherwise incur to take/release the spin_lock over and over
again.

      IB/mlx4: Fix memory leak in do_slave_init · 9bbf282d
      由 Doug Ledford 提交于 
      We create a number of work structs to be queued up to a workqueue, and
on completion of the workqueue handler, the workqueue handler frees the
allocated memory.  If, however, we don't queue the work struct because
the device is going down, then we need to free the memory ourselves.

      IB/mlx4: Optimize freeing of items on error unwind · a39a98ff
      由 Maninder Singh 提交于 
      On failure, we loop through all possible pointers and test them before
calling kfree.  But really, why even attempt to free items we didn't
allocate when we can easily loop through exactly and only the devices
for which the original memory allocation succeeded and free just those.
