From 0853d2c1d849ef69884d2447d90d04007590b72b Mon Sep 17 00:00:00 2001 From: Nitin A Kamble Date: Wed, 5 Nov 2008 15:37:36 -0800 Subject: KVM: Fix cpuid leaf 0xb loop termination For cpuid leaf 0xb the bits 8-15 in ECX register define the end of counting leaf. The previous code was using bits 0-7 for this purpose, which is a bug.
