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.
Thanks,
Naveen

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