the entire memory slot size. Any object may back this memory, including
anonymous memory, ordinary files, and hugetlbfs.

+On architectures that support a form of address tagging, userspace_addr must
+be an untagged address.
+
It is recommended that the lower 21 bits of guest_phys_addr and userspace_addr
be identical. This allows large pages in the guest to be backed by large
pages in the host.
