[RFC 0/4] Virtio uses DMA API for all devices
This patch series is the follow up on the discussions we had before about the RFC titled [RFC,V2] virtio: Add platform specific DMA API translation for virito devices (https://patchwork.kernel.org/patch/10417371/). There were suggestions about doing away with two different paths of transactions with the host/QEMU, first being the direct GPA and the other being the DMA API based translations.
