[PATCH v3 0/6] Support for new CPU model SapphireRapids |

This series aims to add a new CPU model SapphireRapids, and tries to
address the problem stated in
https://lore.kernel.org/all/20220812055751.14553-1-lei4.wang@intel.com/T/#mcf67dbd1ad37c65d7988c36a2b267be9afd2fb30,
so that named CPU model can define its own AMX values, and QEMU won't
pass the wrong AMX values to KVM in future platforms if they have
different values supported.
The original patch is
