Please note that the correct bug number needs to be added
in the format: 

BugLink: https://bugs.launchpad.net/bugs/1834681

and that this bug needs to have the nominations adjusted.

These changes touches code from other architectures as well, but they
seem to be real dependencies and not really compiled for this cloud kernel.
The changes have been also extensively tested.

So as requested, I'm ACK'ing these patches for xenial/linux-gcp and
bionic/linux-gke-4.15:
