Will Deacon b0a2fe148a virtio: Use bounce buffers when VIRTIO_F_IOMMU_PLATFORM is set ... Devices advertising the VIRTIO_F_IOMMU_PLATFORM feature require platform-specific handling to configure their DMA transactions. When handling virtio descriptors for such a device, use bounce buffers to ensure that the underlying buffers are always aligned to and padded to PAGE_SIZE in preparation for platform specific handling at page granularity.
