Merge tag 's390-6.18-3' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux

Pull s390 fixes from Heiko Carstens:

 - Use correct locking in zPCI event code to avoid deadlock

 - Get rid of irqs_registered flag in zpci_dev structure and restore IRQ
   unconditionally for zPCI devices. This fixes sit uations where the
   flag was not correctly updated

 - Fix potential memory leak kernel page table dumper code

 - Disable (revert) ARCH_WANT_OPTIMIZE_HUGETLB_VMEMMAP for s390 again.

   The optimized hugetlb vmemmap code modifies kernel page tables in a
   way which does not work on s390 and leads to reproducible kernel
   crashes due to stale TLB entries. This needs to be addressed with
   some larger changes. For now simply disable the feature

 - Update defconfigs
