Subject: [RFC PATCH 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 initialize
and retrieve the MSR-based features.  The second patch adds support that
will allow a guest to determine if the LFENCE instruction is serializing
on AMD processors.

This series is based on the next branch.
