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.
Tested-by: Zhangfei Gao <zhangfei.gao@xxxxxxxxxx>
On arm64 (Kunpeng920) with uacce.

Thank you very much!

Best regards,
