To be honest probably not. They can open /dev/kvm and call
KVM_GET_SUPPORTED_CPUID to get the same information.

The difference is that /proc/cpuinfo will always have gmet even if the
module parameter is zero, while /dev/kvm won't. Based on your other
message, it seems like you want this to be a bug rather than a
feature, so let's shelve this, can you ack it with "" instead?
