  s390/mm: make pte_free_tlb() similar to pXd_free_tlb() (2023-11-05 22:34:58 +0100)

----------------------------------------------------------------
more s390 updates for 6.7 merge window

- Get rid of s390 specific use of two PTEs per 4KB page with complex
  half-used pages tracking. Using full 4KB pages for 2KB PTEs increases
  the memory footprint of page tables but drastically simplify mm code,
  removing a common blocker for common code changes and adaptations

- Simplify and rework "cmma no-dat" handling. This is a follow up
  for recent fixes which prevent potential incorrect guest TLB flushes

- Add perf user stack unwinding as well as USER_STACKTRACE support for
  user space built with -mbackchain compile option

- Add few missing conversion from tlb_remove_table to tlb_remove_ptdesc

- Fix crypto cards vanishing in a secure execution environment due to
  asynchronous errors

- Avoid reporting crypto cards or queues in check-stop state as online

- Fix null-ptr deference in AP bus code triggered by early config change
  via SCLP

- Couple of stability improvements in AP queue interrupt handling

----------------------------------------------------------------
Alexander Gordeev (4):
      s390/mm: add missing conversion to use ptdescs
      s390/mm: use full 4KB page for 2KB PTE
      s390/mm: use compound page order to distinguish page tables
      s390/mm: make pte_free_tlb() similar to pXd_free_tlb()

Harald Freudenberger (4):
      s390/ap: rework to use irq info from ap queue status
      s390/ap: re-enable interrupt for AP queues
      s390/ap: fix AP bus crash on early config change callback invocation
      s390/ap: fix vanishing crypto cards in SE environment

Heiko Carstens (7):
      s390/perf: implement perf_callchain_user()
      s390: add USER_STACKTRACE support
      s390/cmma: cleanup inline assemblies
      s390/cmma: move parsing of cmma kernel parameter to early boot code
      s390/cmma: move set_page_stable() and friends to header file
      s390/cmma: move arch_set_page_dat() to header file
      s390/cmma: rework no-dat handling

Ingo Franzki (1):
      s390/zcrypt: don't report online if card or queue is in check-stop state
