**We would like the patches to be merged through the virtio tree. Please review, and ack merging the DMA mapping change through that tree. Thanks!** The memory of powerpc secure guests can't be accessed by the hypervisor / virtio device except for a few memory regions designated as 'shared'. At the moment, Linux uses bounce-buffering to communicate with the hypervisor, with a

Hi all, this series replaced the DMA_ATTR_NON_CONSISTENT flag to dma_alloc_attrs with a separate new dma_alloc_pages API, which is available on all platforms. In addition to cleaning up the convoluted code path, this ensures that other drivers that have asked for better support for non-coherent DMA to pages with incurring bounce buffering over can finally be properly supported. I'm still a
