If we move the scope,flags,pasid,vaddr,size fields to vfio_iommu_tlb_invalidate,
then both kernel space vfio and user space vfio needs to do much parsing. So I
may prefer the way above.

From: "Liu, Yi L"
This patch adds support for VFIO_IOMMU_TLB_INVALIDATE cmd in
vfio_iommu_type1.
For SVM virtualization on VT-d, for VFIO_IOMMU_TLB_INVALIDATE, it
calls iommu_ops->do_invalidate() to submit the guest iommu cache
invalidation to pIOMMU.

The assumption is that guest to host device ID mapping should be
resolved prior to calling IOMMU driver. Based on the device handle,
host IOMMU driver can replace certain fields before submit to the
invalidation queue.

This patch adds VFIO_IOMMU_SVM_BIND_TASK for potential PASID table
binding requests.
On VT-d, this IOCTL cmd would be used to link the guest PASID page table
to host. While for other vendors, it may also be used to support other
kind of SVM bind request. Previously,

pIOMMU. In future maybe PASID needs to be replaced.

This patch adds IOCTL processing in vfio_iommu_type1 for
VFIO_IOMMU_SVM_BIND_TASK. Binds the PASID table bind by
calling iommu_ops->bind_pasid_table to link the whole
PASID table to pIOMMU.
For VT-d, it is linking the guest PASID table to host pIOMMU.

When a SVM capable device is assigned to a guest, the first level page
tables are owned by the guest and the guest PASID table pointer is
linked to the device context entry of the physical IOMMU.
