I'm decent with package patch notes now, but wasn't sure how the kernel config 
fit in. I did look for examples but must have found one that missed the 
convention.

I've attached a v2 of the patch that sets it for all the configurations where 
the option was listed. Note that a few had it "enabled" with setting it to "m", 
but I don't think that does anything, per my testing. And looking at the 
documentation, seems like it should be "y": 
https://www.kernelconfig.io/config_hsa_amd

I did not build any of the other kernels, but how does that look now?

Thanks again!
John
