I should also mention, kdevops [0] has the linux-firmware selftests and that
has our kernel config used too [1], you can easily build the selftests
and re-retst then manually on the guest. Soon we hope to leverage this
for automation with 0-day so to ensure keep tabs on all of linus'
kernels and linux-next.

If there is anything we should add to our general config it would be
good to add it there.
