Hi Jason,

These four patches are what I came up with while analyzing a kernel warning
triggered by the ib_srp kernel driver. Please consider these patches for
inclusion in the Linux kernel.

Thanks,

Bart.

Changes compared to v1:
- Restored the dma_set_max_seg_size() call in setup_dma_device(). Reordered
  this patch series to keep it bisectable.

Bart Van Assche (4):
  RDMA/core: Fix ib_dma_max_seg_size()
  rdma_rxe: Increase DMA max_segment_size parameter
  siw: Increase DMA max_segment_size parameter
  RDMA/core: Set DMA parameters correctly

Applied to for-next, thanks
