It does sound odd. Yes, Intel and AMD have differences around CMCI ... but we 
are never
going to send a CMCI to a guest (there is no point, it can't do anything useful 
with the
information, it may do something pointlessly stupid like stop using a guest 
physical page).
The only reason I suggested making MCG_CAP pretend that CMCI was supported was a
small optimization ... if a Linux guest sees that CMCI is supported, it will 
not poll the machine
check banks looking for corrected errors.
