- Return -EIO instead of success when the certificate buffer for SEV
guests is not large enough.
- Allow STIPB to be enabled with legacy IBSR. Legacy IBRS is cleared on
return to userspace for performance reasons, but the leaves user space
vulnerable to cross-thread attacks which STIBP prevents. Update the
documentation accordingly.
