Basically I expect most of these messages to vanish when I stop building as userdebug.

EDIT: logs are indeed quite quiet with user build

I guess I'll try to merge from https://android.googlesource.com/kernel/common/+/refs/heads/android-4.9-q but from I've seen it's not that straightforward.

4.9.219, I merged it from https://github.com/exynos-linux-stable/starlte
