Subject: [PATCH v2 0/4] Use dma_mmap_coherent to support IOMMU mapper

There is a dma_mmap_coherent() API in some architectures.  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.

Hideki EIRAKU (3):
  ARM: dma-mapping: define ARCH_HAS_DMA_MMAP_COHERENT
  media: videobuf2-dma-contig: use dma_mmap_coherent if available
  fbdev: sh_mobile_lcdc: use dma_mmap_coherent if available

Laurent Pinchart (1):
  ALSA: pcm - Don't define ARCH_HAS_DMA_MMAP_COHERENT privately for ARM
