Robin Murphy f7f6634d23 virtio_mmio: Set DMA masks appropriately ... Once DMA API usage is enabled, it becomes apparent that virtio-mmio is inadvertently relying on the default 32-bit DMA mask, which leads to problems like rapidly exhausting SWIOTLB bounce buffers. Ensure that we set the appropriate 64-bit DMA mask whenever possible, with the coherent mask suitably limited for the legacy vring as per a0be1db430 ("virtio_pci: Limit DMA mask to 44 bits for legacy virtio devices").
