Subject: [PATCH v2 0/3] Remove VT-d virtual command interface and IOASID


Hi all,

This patch set removes unused VT-d virtual command interface followed by
removal of the IOASID infrastructure.

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


Thanks,

Jacob
