While it does feel a bit overengineered, it would solve the problem that
we're turning in-KVM handled MSRs into an ABI.
It seems unlikely that userspace is going to know what to do with a
large number of MSRs. I suspect that a small enumerated list will
suffice.
The list can also be 'wildcarded', i.e.
{
u32 index;
u32 mask;
...
}
to make it really short.
I like the idea of wildcards, but I can't quite wrap my head around how
we would implement ignore_msrs in user space with them?
