* Check for KVM_GET_REG_LIST regressions.
*
* Copyright (C) 2020, Red Hat, Inc.
*
* 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")
