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

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",

documentation, seems like it should be "y":

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

Thanks again!
