Linus Torvalds 7f9ec7d816 A small set of updates for x86:
- 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.
