From af24a4e4aec77ef16c1971cf4465f767ba946034 Mon Sep 17 00:00:00 2001 From: Jaswinder Singh Rajput Date: Fri, 15 May 2009 18:42:05 +0530 Subject: [PATCH] KVM: Replace MSR_IA32_TIME_STAMP_COUNTER with MSR_IA32_TSC of msr-index.h Use standard msr-index.h's MSR declaration. MSR_IA32_TSC is better than MSR_IA32_TIME_STAMP_COUNTER as it also solves 80 column issue.
