Merge tag 's390-6.7-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 updates from Alexander Gordeev:

 - Remove unnecessary assignment of the performance event last_tag.

 - Create missing /sys/firmware/ipl/* attributes when kernel is booted
   in dump mode using List-directed ECKD IPL.

 - Remove odd comment.

 - Fix s390-specific part of scripts/checkstack.pl script that only
   matches three-digit numbers starting with 3 or any higher number and
   skips any stack sizes smaller than 304 bytes.

* tag 's390-6.7-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux:
  scripts/checkstack.pl: match all stack sizes for s390
  s390: remove odd comment
  s390/ipl: add missing IPL_TYPE_ECKD_DUMP case to ipl_init()
  s390/pai: cleanup event initialization
