kvm: x86: Add payload operands to kvm_multiple_exception kvm_multiple_exception now takes two additional operands: has_payload and payload, so that updates to CR2 (and DR6 under VMX) can be delayed until the exception is delivered. This is necessary to properly emulate VMX or SVM hardware behavior for nested virtualization. The new behavior is triggered by vcpu->kvm->arch.exception_payload_enabled, which will (later) be set by a new per-VM capability, KVM_CAP_EXCEPTION_PAYLOAD.
