- Add support for systems that are configured with SEV and SEV-ES+ enabled,
but have all ASIDs assigned to SEV-ES+ guests, which effectively makes SEV
unusuable. Cleanup ASID handling to make supporting this scenario less
brittle/ugly.
- Return -EINVAL instead of -EBUSY if userspace attempts to invoke
KVM_SEV{,ES}_INIT on an SEV+ guest. The operation is simply invalid, and
not related to resource contention in any way.

Merge tag 'kvm-x86-svm-6.9' of https://github.com/kvm-x86/linux into HEAD
KVM SVM changes for 6.9:
- Add support for systems that are configured with SEV and SEV-ES+ enabled,
but have all ASIDs assigned to SEV-ES+ guests, which effectively makes SEV
unusuable. Cleanup ASID handling to make supporting this scenario less
brittle/ugly.
- Return -EINVAL instead of -EBUSY if userspace attempts to invoke
KVM_SEV{,ES}_INIT on an SEV+ guest. The operation is simply invalid, and
not related to resource contention in any way.
