Those refer to a different errata, see: https://lore.kernel.org/xen-devel/[email protected]/ So we believe this also affects Haswell, but the errata is not published for those CPUs (yet at least). If/when it's published I'm happy to add it, in the meantime I think we should go with what has been published by Intel. Roger.
