Christoph Hellwig b0f2853b56 nvme-pci: take sglist coalescing in dma_map_sg into account ... Some iommu implementations can merge physically and/or virtually contiguous segments inside sg_map_dma. The NVMe SGL support does not take this into account and will warn because of falling off a loop. Pass the number of mapped segments to nvme_pci_setup_sgls so that the SGL setup can take the number of mapped segments into account.
