That's always fun.

We can't change struct kvm_sregs, since the structure size is encoded in
the ioctl number. We need a new struct and new ioctls. The same was
done for mpstate, for example.
There's more info needed, btw. Whether the guest is in guest mode or
host mode; what the current vmcs is; the value of eflags.if at the time
vmrun was executed; and probably more.
