Hi Andreas, thx for the pointers. I tested the patches but unfortunately they don't enable the cpus. Oh sorry, I just read failed to come online but didn't notice it's about 4-7 only. All eight are available as nodes under /cpus on for-next [1], so no clue on my part. The Samsung guys will know better.
