Comment 7 for bug 1735420

So I just did a brief test - stock kernel first and then the modified one:

ubuntu@ubu-vm-01:~$ uname -a
Linux ubu-vm-01 4.4.0-116-generic #140-Ubuntu SMP Mon Feb 12 21:21:31 UTC 2018 s390x s390x s390x GNU/Linux
ubuntu@ubu-vm-01:~$ ls -la /dev/kvm
crw------- 1 root root 10, 232 Mar 13 22:42 /dev/kvm

ubuntu@ubu-vm-01:~$ uname -a
Linux ubu-vm-01 4.4.0-116-generic #140~lp1735420 SMP Tue Mar 13 21:48:51 UTC 2018 s390x s390x s390x GNU/Linux
ubuntu@ubu-vm-01:~$ ls -la /dev/kvm
crw------- 1 root root 10, 232 Mar 14 03:47 /dev/kvm
ubuntu@ubu-vm-01:~$ kvm-ok
INFO: /dev/kvm exists
KVM acceleration can be used
ubuntu@ubu-vm-01:~$

So I couldn't identify a difference between both kernels so far ...
