[PATCH 0/2] virtio: Support encrypted memory on powerpc secure guests
**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
