Hi all,

This patch set removes unused VT-d virtual command interface followed by
clean up in the IOASID code.

This has only been tested on x86 platforms, need help with testing on ARM
SMMU and other architectures.

I also hope to collect feedback on the upcoming clean up and enhancements
below:
1. Consolidate VT-d private SVA PASID array with IOASID common code
2. As we retain the global IOASID allocator, we need some level of resource
management. I want to restart the effort to include IOASID under misc
cgroup.

Thanks,

Jacob

this should go with adding global pasid allocator to iommufd.

before that we don't have such cgroup requirement.
