H A Dvp_vdpa.cdiff d8945ec411209272bcd4ae9e75ea1b078257e492 Tue Aug 31 12:36:31 CEST 2021 Xie Yongji <xieyongji@bytedance.com> vdpa: Support transferring virtual addressing during DMA mapping

This patch introduces an attribute for vDPA device to indicate
whether virtual address can be used. If vDPA device driver set
it, vhost-vdpa bus driver will not pin user page and transfer
userspace virtual address instead of physical address during
DMA mapping. And corresponding vma->vm_file and offset will be
also passed as an opaque pointer.
