 * Check for KVM_GET_REG_LIST regressions.

 *
 * When attempting to migrate from a host with an older kernel to a host
 * with a newer kernel we allow the newer kernel on the destination to
 * list new registers with get-reg-list. We assume they'll be unused, at
 * least until the guest reboots, and so they're relatively harmless.
 * However, if the destination host with the newer kernel is missing
 * registers which the source host with the older kernel has, then that's
 * a regression in get-reg-list. This test checks for that regression by
 * checking the current list against a blessed list. We should never have
 * missing registers, but if new ones appear then they can probably be
 * added to the blessed list. A completely new blessed list can be created
 * by running the test with the --list command line argument.
 *
 * Note, the blessed list should be created from the oldest possible
 * kernel. We can't go older than v4.15, though, because that's the first
 * release to expose the ID system registers in KVM_GET_REG_LIST, see
 * commit 93390c0a1b20 ("arm64: KVM: Hide unsupported AArch64 CPU features
 * from guests"). Also, one must use the --core-reg-fixup command line
 * option when running on an older kernel that doesn't include df205b5c6328
 * ("KVM: arm64: Filter out invalid core register IDs in KVM_GET_REG_LIST")
