Subject: [PATCH 0/2] Remove VT-d virtual command interface

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
