I personally don't have a preference. I'll defer to Alex or Kirti to provide
that guidance. It may make certains things like dealing with dma fault regions
and etc easier using vfio calls from vfio_pci_private.h later on for vSVM
support. It also may be the better code review and maintenance domain and
alleviate Vinod having to deal with that portion since it's not dmaengine domain.
