Hi Zoltan,

I told you on IRC I'd check on an APU2, but that's in production on a 
remote site so if it goes belly up people won't be happy. So when you 
mentioned Ryzen on the mailing list here I figured I could as well do 
it on my desktop ;-).

Dmesg excerpts below. I added the 17h microcode file to 
/lib/firmware/amd-ucode/ manually, but it looks like it works. Tested 
with master and kernel 4.4.112 (courtesy of Kevin's patch).

[ 0.408053] smpboot: CPU0: AMD Ryzen 7 1800X Eight-Core Processor 
(family: 0x17, model: 0x1, stepping: 0x1)
[ 0.418276] Performance Events: Fam17h core perfctr, AMD PMU driver.
