2   Expose the address(es) of the ACPI RSD PTR table(s) and the SMBIOS entry
3   point(s) in a MB-aligned structure to the hypervisor.
5   The hypervisor locates the MB-aligned structure based on the signature GUID
6   that is at offset 0 in the structure. Once the RSD PTR and SMBIOS anchor
7   address(es) are retrieved, the hypervisor may perform various ACPI and SMBIOS
