So if it should be applied down to xenial, it needs to be applied to
bionic, too.

Bug description:
  Description:   kernel: s390/cpum_cf,perf: change DFLT_CCERROR counter name
  Symptom:       Counter name CCERROR is misleading.
  Problem:       Change the counter name DLFT_CCERROR to DLFT_CCFINISH on
                 IBM z15.  This counter counts completed DEFLATE instructions
                 with exit code 0, 1 or 2. Since exit code 0 means success
                 and exit code 1 or 2 indicate errors, change the counter
                 name to avoid confusion.  This counter is incremented each
                 time the DEFLATE instruction completed regardless if an
                 error was detected or not.
  Solution:      Rename s390 z15 counter named DFLT_CCERROR to DFLT_CCFINISH
  Reproduction:  Command # ls /sys/devices/cpum_cf/events/DFLT_CCERROR
                 currently succeeds. After this patch has been applied the
                 command does not work anymore. The file does not exist
                 anymore. Use command 
                 # ls /sys/devices/cpum_cf/events/DFLT_CCFINISH
                 instead.
