From ca60dfbb69afb549e33527cbf676e4daf8febfb5 Mon Sep 17 00:00:00 2001 From: Sheng Yang Date: Tue, 24 Jun 2008 17:02:38 +0800 Subject: [PATCH] KVM: VMX: Rename misnamed msr bits MSR_IA32_FEATURE_LOCKED is just a bit in fact, which shouldn't be prefixed with MSR_. So is MSR_IA32_FEATURE_VMXON_ENABLED.
