  Revert "s390/mm: Allow large pages for KASAN shadow mapping" (2024-11-29 13:41:11 +0100)

----------------------------------------------------------------
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

----------------------------------------------------------------

      s390/mm: Remove bogus comment in __tlb_flush_mm()

      s390/stacktrace: Use break instead of return statement
      s390: Add missing _TIF defines
      s390: Add ARCH_HAS_PREEMPT_LAZY support

      s390/spinlock: Use R constraint for arch_load_niai4()
      s390/spinlock: Use flag output constraint for arch_cmpxchg_niai8()

Niklas Schnelle (3):
      s390/debug: Pass in and enforce output buffer size for format handlers
