Linus Torvalds b4f7f01ea1 s390 fixes for 6.18-rc4
- 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
