Hi Ziviani,
Thanks for the submission. I didn't review the entire patch set but
there are a few points that you probably need to change.
When cherry-picking from mainline please use the options -s (to add your
Signed-by-off) and -x (to add a line the its original commit).
It's also necessary to include the BugLink tag to all patches and use
the appropriate suffix on the commit message for any custom patches you
made (usually "UBUNTU: SAUCE: "). Some of these rules can be found in
this wiki page:
https://wiki.ubuntu.com/Kernel/Dev/StablePatchFormat
You should also include to the commit message body the rational for any
custom change and conflict resolution.
Finally, I tried to apply the set on top of the master-next branch and
it failed. That probably means it needs to be rebased.

> - Again, the only change necessary from commit (upstream f7b1a77 Merge tag 'kvm-s390-next-4.12-1') was due to the entries it has added into include/uapi/linux/kvm.h. Since the upstream f7b1a77 is a merge with a huge change that would be very hard to apply, I decided to create a commit adding those two entries.
