> 
> Shared virtual address (SVA), a.k.a, Shared virtual memory (SVM) on Intel platforms
> allow address space sharing between device DMA and applications.
> SVA can reduce programming complexity and enhance security.
> This series is intended to enable SVA virtualization, i.e. enable use of SVA within a
> guest user application.
> 
> This is the remaining portion of the original patchset that is based on Joerg's x86/vt-
> d branch. The preparatory and cleanup patches are merged here.
> (git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu.git)
> 
> Only IOMMU portion of the changes are included in this series. Additional support is
> needed in VFIO and QEMU (will be submitted separately) to complete this
> functionality.
> 
> To make incremental changes and reduce the size of each patchset. This series does
> not inlcude support for page request services.
> 
> In VT-d implementation, PASID table is per device and maintained in the host.
> Guest PASID table is shadowed in VMM where virtual IOMMU is emulated.
