There is slight update from AMD [1], relevant part for you:

*AMD Microcode Updates for GPZ Variant 2/Spectre*

In addition, microcode updates with our recommended mitigations addressing 
Variant 2 (Spectre) have been released to our customers and ecosystem partners 
for AMD processors dating back to the first “Bulldozer” core products introduced 
in 2011.

AMD customers will be able to install the microcode by downloading BIOS updates 
provided by PC and server manufacturers and motherboard providers.  Please check 
with your provider for the latest updates.

Unfortnately, I dont know where to get that microcode. Any ideas?

And also, it changed in [2] the claims that IBPB should be made on context switch.
