Tom Lendacky 62d88fc0fb KVM: x86: Add a framework for supporting MSR-based features

commit 801e459a6f upstream

Provide a new KVM capability that allows bits within MSRs to be recognized
as features.  Two new ioctls are added to the /dev/kvm ioctl routine to
retrieve the list of these MSRs and then retrieve their values. A kvm_x86_ops
callback is used to determine support for the listed MSR-based features.
