 * The domctl interface is versioned via the interface_version

 *
 * - 0x00000007: Xen 4.1
 * - 0x00000008: Xen 4.2
 * - 0x00000009: Xen 4.3 & 4.4
 * - 0x0000000a: Xen 4.5
 * - 0x0000000b: Xen 4.6
 * - 0x0000000c: Xen 4.7
 *
 * When adding a new subop be sure to include the variants used by all
 * of the above, both here and in syswrap-xen.c
 *
 * Structs which are identical in all supported versions have no
 * version suffix. Structs which do differ are defined multiple times
 * and use the suffix of the latest version to contain that particular
 * variant.
