Hi folks,

The former part of this series introduces the IOMMU interfaces to attach
or detach an iommu domain to/from a pasid of a device, and refactors the
exsiting IOMMU SVA implementation by assigning an SVA type of iommu
domain to a shared virtual address and replacing sva_bind/unbind iommu
ops with a set_dev_pasid domain ops.

The latter part changes the existing I/O page fault handling framework
from only serving SVA to a generic one. Any driver or component could
handle the I/O page faults for its domain in its own way by installing
an I/O page fault handler.

This series has been functionally tested on an x86 machine and compile
tested for all architectures.

This series is also available on github:

Please review and suggest.

Thank you all for review and test. I have updated this series and
uploaded a new version at

https://github.com/LuBaolu/intel-iommu/commits/iommu-sva-refactoring-v12

Zhangfei and Tony have tested it on real Intel and arm64 hardware.

I will soon post it for further review.

Best regards,
baolu
