[PATCH v2 0/2] iommu_aux_at(de)tach_device() enhancement

[Lu Baolu]

This series aims to enhance the iommu_aux_at(de)tach_device() api's
so that some generic iommu api's like iommu_get_domain_for_dev() could
also work for vfio/mdev device.

The initial version of this series was post at

https://lkml.org/lkml/2020/6/26/1118

This version is evolved according to Robin's feedback.

Your comments are very appreciated.

Best regards,
baolu
