Merge tag 's390-5.8-4' of git://git./linux/kernel/git/s390/linux

Pull s390 fixes from Heiko Carstens:

 - Initialize jump labels before early command line parsing in order to
   make init_on_alloc and init_on_free options work

 - Fix vfio-ccw build error due to missing include

 - Prevent callchain data collection with hardware sampling, since the
   callchains simply do not exist

 - Prevent multiple registrations of the same zPCI function

 - Update defconfigs
