fb_mmap() implemented in fbmem.c uses smem_start as the physical
address of the frame buffer.  In the sh_mobile_lcdc driver, the
smem_start is a dma_addr_t that is not a physical address when IOMMU is
enabled.  dma_mmap_coherent() maps the address correctly.

I will push the patch to v3.7 through my tree.

I'd like to use this patch to test IOMMU implementation of Renesas
IPMMU.  But I could not find it in v3.7-rc8.  Could you please tell me if
this has already been merged somewhere or not?

I'm afraid the patch got delayed to v3.8, sorry about that. I've sent a pull 
request for v3.8, the patch is currently in linux-next 
(bf10a53765b4435a5349a92a5a51753902ed86f1) and will be merged during the next 
merge window (which should open in the very near future).
