From 519efbc0b3b6004a3b98d66a446bce30852c8171 Mon Sep 17 00:00:00 2001 From: Andreas Herrmann3 Date: Wed, 30 Jan 2008 13:33:35 +0100 Subject: [PATCH] x86: fix cpu MHz reporting for AMD family 0x11 Fix cpu MHz reporting for AMD family 0x11 when powernow-k8 is disabled. Just adhere to the CONSTANT_TSC feature bit for AMD CPUs when deciding whether cpu_khz needs calibration. The additional check for CPU family is not needed and prevents calibration for future CPUs.
