Heresy! Everyone knows the one true way is "KVM: x86/mmu:"
$ glo | grep "KVM: MMU:" | wc -l
740
$ glo | grep "KVM: x86/mmu:" | wc -l
403
Dammit, I'm the heathen...
I do think we should use x86/mmu though. VMX and SVM (and nVMX and nSVM) are ok
because they're unlikely to collide with other architectures, but every arch has
an MMU...
