Merge tag 's390-6.12-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Heiko Carstens:

 - Fix PCI error recovery by handling error events correctly

 - Fix CCA crypto card behavior within protected execution environment

 - Two KVM commits which fix virtual vs physical address handling bugs
   in KVM pfault handling

 - Fix return code handling in pckmo_key2protkey()

 - Deactivate sclp console as late as possible so that outstanding
   messages appear on the console instead of being dropped on reboot

 - Convert newlines to CRLF instead of LFCR for the sclp vt220 driver,
   as required by the vt220 specification

 - Initialize also psw mask in perf_arch_fetch_caller_regs() to make
   sure that user_mode(regs) will return false

 - Update defconfigs
