Subject: [GIT PULL] more s390 updates for 6.13 merge window
Hi Linus,
please pull a couple more s390 updates for the 6.13 merge window.
Thanks,
Heiko

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
----------------------------------------------------------------
Alexander Gordeev (1):
s390/mm: Remove bogus comment in __tlb_flush_mm()
Claudio Imbrenda (1):
s390/vfio-ap: Remove gmap_convert_to_secure() from vfio_ap_ops
Gerald Schaefer (4):
s390/mm: Rearrange region-third and segment table entry SW bits
s390/mm: Introduce region-third and segment table entry present bits
s390/mm: Introduce region-third and segment table swap entries
s390/mm: Add PTE_MARKER support for hugetlbfs mappings
Heiko Carstens (14):
s390/stacktrace: Use break instead of return statement
s390: Add missing _TIF defines
s390: Add ARCH_HAS_PREEMPT_LAZY support
s390/ap: Replace xchg() with WRITE_ONCE()
KVM: s390: Use try_cmpxchg() instead of cmpxchg() loops
KVM: s390: Remove one byte cmpxchg() usage
KVM: s390: Increase size of union sca_utility to four bytes
s390/mm/hugetlbfs: Add missing includes
s390: Support PREEMPT_DYNAMIC
s390/spinlock: Use symbolic names in inline assemblies
s390/spinlock: Remove condition code clobber from arch_spin_unlock()
s390/spinlock: Generate shorter code for arch_spin_unlock()
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
s390/pci: Fix leak of struct zpci_dev when zpci_add_device() fails
s390/pci: Fix potential double remove of hotplug slot
Thomas Richter (1):
s390/cpum_sf: Simplify release of SDBs and SDBTs
Vasily Gorbik (3):
s390/entry: Mark IRQ entries to fix stack depot warnings
s390/mm: Allow large pages for KASAN shadow mapping
