The purpose of this function is to give a short description that would
be change when a host CPU is replaced with a different model. This is
currently implemented by reading /proc/cpuinfo.

It should be implemented for all architectures for which the QEMU driver
stores host CPU data in the capabilities cache. In other words for archs
that support host-model CPUs.
