Date: Sun, 2 Jan 2011 02:18:52 -0500 From: Paul Gortmaker <paul.gortmaker@...driver.com> To: stable@...nel.org, linux-kernel@...r.kernel.org Cc: stable-review@...nel.org, Zachary Amsden <zamsden@...hat.com>, Marcelo Tosatti <mtosatti@...hat.com>, Paul Gortmaker <paul.gortmaker@...driver.com> Subject: [34-longterm 236/260] KVM: x86: Fix SVM VMCB reset From: Zachary Amsden <zamsden@...hat.com> commit 58877679fd393d3ef71aa383031ac7817561463d upstream. On reset, VMCB TSC should be set to zero. Instead, code was setting tsc_offset to zero, which passes through the underlying TSC.
