That's easy - Carrizo :-P

But seriously, should we do some mapping of those somewhere and then
have people look at them and point at the exact f/m/s they mean?

This issue has come up in the past too; it is one of the reasons I added
f/m/s to the boot string:

[    0.303209] AMD-Vi: Command-line override present for HPET id 0 - ignoring
[    0.389353] ..TIMER: vector=0x30 apic1=0 pin1=2 apic2=-1 pin2=-1
[    0.542398] smpboot: CPU0: AMD FX(tm)-8350 Eight-Core Processor (family: 0x15, model: 0x2, stepping: 0x0)
								    ^^^^^^^^^^^
[    0.552219] Performance Events: Fam15h core perfctr, AMD PMU driver.
