Subject: i386/kvm: support guest access CORE cstate
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Git-commit: d38d201f0ed092b8c7f7738a5db8428e12cb04b6 (partial)
References: bsc#1179725

Allow guest reads CORE cstate when exposing host CPU power management capabilities
to the guest. PKG cstate is restricted to avoid a guest to get the whole package
information in multi-tenant scenario.
