Subject: [PATCH v2 0/2] Migo-R: reserve memory block with memblock APIs

Re-spinn of "[PATCH] sh: migor: Reserve memory block for CEU" with additional
patch on top to post-pone page_to_pfn() mapping during mmap() on DMA memory.

Laurent is probably working on a proper fix, so I'm just copying the iommu list
here to make them aware of the problem on SH4 architecture, but please do not
consider that patch for inclusion for now.

Thanks
