First of all, thanks a lot for taking care of these patches. Much appreciated.

One thing to note, though, is that the four patches (31, 32, 33 and 39
in this series), which we initially made for fixing the problems
related, were later reverted and replaced by a cleaner solution.
Please take a look at this series on our gerrit:

https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/442390/
https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/442392/
https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/442391/

Perhaps we could skip this intermediate solution and just go with the
above 3 patches?

Best regards,
Tomasz
