Sorry for not noticing it earlier, but could you please
fix series to use cpu type names instead of cpu_model?

I've just posted series that completes cpu_model refactoring
  [PATCH 00/24] generalize parsing of cpu_model (part 4)
which removes remnants of the code using cpu_model to
instantiate CPUs, including reworking how default
cpu type for *-user is picked up.

After that cpu_model shouldn't be used anywhere in the code
except of routines that process "-cpu" CLI and cpu types
should be used directly.

So you might not need 1/4 after that or it would have
to be reworked and probably other patches where where
cpu_model is used.
