This API provides a mmap function for memory allocated by dma_alloc_coherent(). Some drivers mmap a dma_addr_t returned by dma_alloc_coherent() as a physical address. But such drivers do not work correctly when IOMMU mapper is used. v2: - Rebase on fbdev-next branch of git://github.com/schandinat/linux-2.6.git. - Initialize .fb_mmap in both sh_mobile_lcdc_overlay_ops and sh_mobile_lcdc_ops. - Add Laurent's clean up patch.
