2317This queries KVM for preferred CPU target type which can be emulated
2318by KVM on underlying host.

2320The ioctl returns struct kvm_vcpu_init instance containing information
2321about preferred CPU target type and recommended features for it. The
2322kvm_vcpu_init->features bitmap returned will have feature bits set if
2323the preferred target recommends setting these features, but this is
2324not mandatory.

2326The information returned by this ioctl can be used to prepare an instance
2327of struct kvm_vcpu_init for KVM_ARM_VCPU_INIT ioctl which will result in
2328in VCPU matching underlying host.
