Thanks Eric.

Have tested vfio mode in qemu on Hisilicon arm64 platform, using gIOVA
qemu command: -machine virt,gic_version=3,iommu=smmuv3 -device 
vfio-pci,host=0000:75:00.1

Tested-by: Zhangfei Gao <zhangfei.gao@linaro.org>
qemu: https://github.com/eauger/qemu/tree/v4.1.0-rc0-2stage-rfcv5
kernel: https://github.com/eauger/linux/tree/v5.3.0-rc0-2stage-v9
