 Log Message:
 nvmm: Don't report physical lapic freq as virtual lapic freq.
 
 The virtual lapic emulated by qemu in software always ticks at 1 GHz,
 but the physical lapic on my laptop, for example, ticks at 24 MHz.
 
 In order for this to work as iMil intended, we need some way for the
 hypervisor (such as qemu) to tell nvmm what its lapic frequency is.
 Until we have that, we can't correctly report any alleged lapic
 frequency to the guest.
