Hi, commit 99db94940 "IB/core: Remove ib_device.dma_device" breaks infiniband on s390 (and I think also other archs that do something like to_pci_dev(dev) in one of their dma_ops callbacks). With this commit you use the dma_ops of the device that called ib_register_device but you call e.g. dma_map with ib_device->dev as an argument. S390's (pci specific) dma_map uses to_pci_dev(dev) to look into the pci device (and its arch specific data) and oopses. Calling dma_map with ib_device->dev.parent would work but then it wouldn't make sense to copy dma_ops and mask from ib_device->dev.parent to ib_device->dev..
