The other updates some details about the "PAuth" (Pointer Authentication) feature. I replaced the "TCG vCPU Features" heading with "PAuth" because of this: before this change, the section says, it is about "CPU features that are specific to TCG". But it has only PAuth-related parameters under it. Since PAuth is relevant to both KVM and TCG, I moved them under a separate PAuth section, instead of duplicating it. But now we have a small inconsistency - there's a KVM-only CPU features section, but no TCG-only section. I thought when there are more TCG-only CPU features, that section can be added back in. Or I can add that back in, if anyone feels strongly about it.
