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

ChangeLog:
v3:
- moved helper functions for PASID under SVA code, avoided circular inclusion
between mm.h and iommu.h
- deleted makefiles
- put rename under a different patch

Jacob Pan (3):
iommu/vt-d: Remove virtual command interface
iommu/sva: Move PASID helpers to sva code
iommu/ioasid: Rename INVALID_IOASID

Jason Gunthorpe (2):
