Christoph Hellwig	3be6d9b6da	dma-virt: remove dma_supported and mapping_error methods ... These just duplicate the default behavior if no method is provided. Signed-off-by: Christoph Hellwig <hch@lst.de>	2017-06-28 06:54:41 -07:00
Bart Van Assche	551199aca1	lib/dma-virt: Add dma_virt_ops ... Several RDMA drivers (hfi1, qib and rxe) expect that ib_sge.addr is a virtual address. Provide DMA mapping operations that are suitable for these drivers.
