The handlers for LSTAR and the like are dead code with !CONFIG_HVM_FEP as far
as I can tell. The question I'm asking is whether there is another code path
that might invoke MSR handlers for non-intercepted MSRs. I can't see it, but
I'm not sure.
If there isn't I'm considering (conditionally) getting rid of them.
Cheers,
Alejandro
