Subject[077/103] KVM: x86: Fix SVM VMCB reset
2.6.35-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Marcelo Tosatti <mtosatti@redhat.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.
