[PATCH v1 19/23] KVM: x86: Allow FRED/LKGS/WRMSRNS to be exposed to guests

[Xin Li]

Allow FRED/LKGS/WRMSRNS to be exposed to guests, thus a guest OS could see
these features when the guest is configured with FRED/LKGS/WRMSRNS in Qemu.

A qemu patch is required to expose FRED/LKGS/WRMSRNS to KVM guests.
