Something I forgot to mention: doing it this way is beneficial 
for suspend/resume and is generally the modern way of doing a 
self-sufficient in-kernel driver.

The natural next step will be to extend this approach to Intel 
CPUs (there's nothing inherently AMD specific about it) - that 
is still work in progress and was not ready for this merge 
window.

Just in case someone is wondering.
