Subject: [PATCH v2 0/2] KVM: MSR-based features

The following series implements support within KVM for MSR-based features.
The first patch creates the MSR-based feature framework used to retrieve
the available MSR-based features.  The second patch makes use of the
framework to allow a guest to determine if the LFENCE instruction is
serializing on AMD processors.

This series is based on the master branch of the KVM git tree.
