No, I was planning to send it at -rc1 with a CC stable.

This patch set enhances the DMA Contiguous Memory Allocator on x86.
Currently the DMA CMA is only supported with pci-nommu dma_map_ops
and furthermore it can't be enabled on x86_64. But I would like to
allocate big contiguous memory with dma_alloc_coherent() and tell it
to the device that
Calling dma_alloc_coherent() with __GFP_ZERO must return zeroed memory.
But when the contiguous memory allocator (CMA) is enabled on x86 and
the memory region is allocated by dma_alloc_from_contiguous(), it
doesn't return zeroed memory. Because dma_generic_alloc_coherent()
forgot to fill the
This adds support for the DMA Contiguous Memory Allocator for intel-iommu.
This change enables dma_alloc_coherent() to allocate big contiguous
memory.
It is achieved in the same way as nommu_dma_ops currently does, i.e.
trying to allocate memory by dma_alloc_from_contiguous() and alloc_pages()
is
This introduces memblock_alloc_range() which allocates memblock from
the specified range of physical address. I would like to use this
function to specify the location of CMA.
