Thanks, unfortunately I just noticed that those patches are from an older
version of the series, the latest being v3
https://lore.kernel.org/linux-iommu/20211201173323.1045819-1-jean-philippe@linaro.org/

Since Joerg picked the latest one in his tree [1], I was wondering if you
could drop those patches?

51a4c54f35ae iommu/virtio: Support identity-mapped domains
523e55a406aa iommu/virtio: Pass end address to viommu_add_mapping()
97301219dfb2 iommu/virtio: Sort reserved regions
720552613526 iommu/virtio: Support bypass domains
01444b9c772f iommu/virtio: Add definitions for VIRTIO_IOMMU_F_BYPASS_CONFIG

Thanks,
Jean
