    Subjectbus_to_virt equivalent
    Hi,

    I am trying to port bus_to_virt and virt_to_bus to the
    DMA-mapping scheme.
    I found a way to move virt_to_bus() as follows:
    page = virt_to_page(cmd->request_buffer);
    offset = (unsigned long)address & ~PAGE_MASK;
    dma_addr_t addr = pci_map_page(dev, page, offset,
    size,direction);

    But now I want to get virtual address for dma_addr_t.

    Any help is greatly appreciated.

    with regards,
    Anil
