As I understand the above algorithm, we find a vfio_dma
overlapping the request and populate the bitmap for that range. Then
we go back and put_user() for each byte that we touched. We could
instead simply work on a one byte buffer as we enumerate the requested
range and do a put_user()

VFIO_IOMMU_DIRTY_PAGES ioctl performs three operations:
- Start pinned and unpinned pages tracking while migration is active
- Stop pinned and unpinned dirty pages tracking. This is also used to
stop dirty pages tracking if migration failed or cancelled.
- Get dirty pages bitmap. This ioctl
