Subject[PATCH 16/16] KVM: VMX: Allow KVM_INTEL when building for Centaur and/or Zhaoxin CPUs
Change the dependency for KVM_INTEL, i.e. KVM w/ VMX, from Intel CPUs to
any CPU that has IA32_FEATURE_CONTROL MSR and thus VMX functionality.
This effectively allows building KVM_INTEL for Centaur and Zhaoxin CPUs.

To compile this as a module, choose M here: the module
will be called kvm-intel.
