Subject: [PATCH AUTOSEL 5.2 84/94] tools/power turbostat: Fix Haswell Core systems

From: Len Brown <len.brown@...el.com>

[ Upstream commit cd188af5282d9f9e65f63915b13239bafc746f8d ]

turbostat: cpu0: msr offset 0x630 read failed: Input/output error

because Haswell Core does not have C8-C10.

Output C8-C10 only on Haswell ULT.

Fixes: f5a4c76ad7de ("tools/power turbostat: consolidate duplicate model numbers")
