Subject: [PATCH v6 46/49 RESEND] tools/power/turbostat: Switch to new Intel CPU model defines
Date: Tue, 11 Jun 2024 10:19:50 -0700
Message-ID: <20240611171950.352734-1-tony.luck@intel.com>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

New CPU #defines encode vendor and family as well as model.

N.B. Copied VFM_*() defines here from <asm/cpu_device_id.h> to avoid
an application picking a second internal kernel header file.

Len: This was snet earlier as part of a patch bomb. But I think I failed
to send a copy directly "To:" you so you'd see it.

Please check it over. Let me know if you need any changes to apply it.
