[Qemu-arm] [PATCH v4 0/4] ARM SMMUv3: IOTLB Emulation and VHOST Support

[Eric Auger]

This series brings translation configuration caching and IOTLB
emulation.  The last patch implements VHOST integration and
allows to run VSMMUv3 along with VHOST emulated end points.

The first patch fixes the passthrough mode bug reported by Jia.
It reworks the translate function and this series needed to be
rebased on it.

Best Regards

Eric
