Some devices may have a non-zero DMA offset, i.e an offset between the DMA address and the physical address. Such an offset can be encoded into the dma_pfn_offset field of "struct device", but the SuperH implementation of the DMA mapping API does not observe this information. This commit fixes that by ensuring the DMA address is properly calculated depending on this DMA offset.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
