Please apply commit d81cadbe1642 ("KVM: SVM: Disable AVIC on SNP-enabled system without HvInUseWrAllowed feature") to the stable v6.12 tree. This patch prevents a kernel BUG by disabling AVIC on systems without suitable support for AVIC to work when SEV-SNP support is enabled in the host.

We need an ack from the KVM maintainers before we can take this.

Sure. Adding Sean and Paolo.

AIUI, there's no sane alternative, so:

Now queued up, thanks.
