Linus Torvalds 509f806f7f more s390 updates for 6.13 merge window 
- Add swap entry for hugetlbfs support
 
 - Add PTE_MARKER support for hugetlbs mappings; this fixes a regression
   (possible page fault loop) which was introduced when support for
   UFFDIO_POISON for hugetlbfs was added
 
 - Add ARCH_HAS_PREEMPT_LAZY and PREEMPT_DYNAMIC support
 
 - Mark IRQ entries in entry code, so that stack tracers can filter out the
   non-IRQ parts of stack traces. This fixes stack depot capacity limit
   warnings, since without filtering the number of unique stack traces is
   huge
 
 - In PCI code fix leak of struct zpci_dev object, and fix potential double
   remove of hotplug slot
 
 - Fix pagefault_disable() / pagefault_enable() unbalance in
   arch_stack_user_walk_common()
 
 - A couple of inline assembly optimizations, more cmpxchg() to
   try_cmpxchg() conversions, and removal of usages of xchg() and cmpxchg()
   on one and two byte memory areas
 
 - Various other small improvements and cleanups
