Turning on CPU_FTR_POWER7 for them is gonna look a bit silly.
As we discussed online, we could call it CPU_FTR_VMX_COPY and start thinking about a better way to solve the CPU feature bit mess. One idea would be to have a structure of function pointers for each CPU that gets runtime patched into the right places, similar to how we do some of the MMU fixups.
