That's not exactly accurate.
This is a decent list of every architecture's cpuinfo output generators:
Perusing through them you will discover the following:
cpu flags: sh
features: arm, avr32, ia64, openrisc, s390, unicore32
flags: tile, x86
Reasons why these things matter:
I'm new to openstack and learning my way around, but it would be quite
nice to have a heterogenous cluster with an ability to request certain
cpu features/flags and to have those characteristics automatically
