       RIP: 0010:mod_node_page_state+0x6/0x90
      
      Currently, when memory is hot-plugged or hot-removed the accounting is
      done based on the assumption that memmap is allocated from the same node
      as the hot-plugged/hot-removed memory, which is not always the case.
      
      In addition, there are challenges with keeping the node id of the memory
      that is being remove to the time when memmap accounting is actually
      performed: since this is done after remove_pfn_range_from_zone(), and
      also after remove_memory_block_devices(). Meaning that we cannot use
      pgdat nor walking though memblocks to get the nid.
      
      Given all of that, account the memmap overhead system wide instead.
      
      For this we are going to be using global atomic counters, but given that
      memmap size is rarely modified, and normally is only modified either
      during early boot when there is only one CPU, or under a hotplug global
      mutex lock, therefore there is no need for per-cpu optimizations.
      
      Also, while we are here rename nr_memmap to nr_memmap_pages, and
      nr_memmap_boot to nr_memmap_boot_pages to be self explanatory that the
      units are in page count.

      mm: add system wide stats items category · f4cb78af
      Pasha Tatashin authored
      /proc/vmstat contains events and stats, events can only grow, but stats
      can grow and shrink.
      
      vmstat has the following:
      -------------------------
      NR_VM_ZONE_STAT_ITEMS:	per-zone stats
      NR_VM_NUMA_EVENT_ITEMS:	per-numa events
      NR_VM_NODE_STAT_ITEMS:	per-numa stats
      NR_VM_WRITEBACK_STAT_ITEMS:	system-wide background-writeback and
      				dirty-throttling tresholds.
      NR_VM_EVENT_ITEMS:	system-wide events
      -------------------------
      
      Rename NR_VM_WRITEBACK_STAT_ITEMS to NR_VM_STAT_ITEMS, to track the
      system-wide stats, we are going to add per-page metadata stats to this
      category in the next patch.
      
      Also delete unused writeback_stat_name().

      mm: don't account memmap on failure · ace0741a
      Pasha Tatashin authored
      Patch series "Fixes for memmap accounting", v4.
      
      Memmap accounting provides us with observability of how much memory is
      used for per-page metadata: i.e. "struct page"'s and "struct page_ext".
      It also provides with information of how much was allocated using
      boot allocator (i.e. not part of MemTotal), and how much was allocated
      using buddy allocated (i.e. part of MemTotal).
      
      This small series fixes a few problems that were discovered with the
      original patch.
      
      
      This patch (of 3):
      
      When we fail to allocate the mmemmap in alloc_vmemmap_page_list(), do not
      account any already-allocated pages: we're going to free all them before
      we return from the function.

      mm/hugetlb: fix hugetlb vs. core-mm PT locking · 5f75cfbd
      David Hildenbrand authored
      We recently made GUP's common page table walking code to also walk hugetlb
      VMAs without most hugetlb special-casing, preparing for the future of
      having less hugetlb-specific page table walking code in the codebase. 
      Turns out that we missed one page table locking detail: page table locking
      for hugetlb folios that are not mapped using a single PMD/PUD.
      
      Assume we have hugetlb folio that spans multiple PTEs (e.g., 64 KiB
      hugetlb folios on arm64 with 4 KiB base page size).  GUP, as it walks the
      page tables, will perform a pte_offset_map_lock() to grab the PTE table
      lock.
      
      However, hugetlb that concurrently modifies these page tables would
      actually grab the mm->page_table_lock: with USE_SPLIT_PTE_PTLOCKS, the
      locks would differ.  Something similar can happen right now with hugetlb
      folios that span multiple PMDs when USE_SPLIT_PMD_PTLOCKS.
      
      This issue can be reproduced [1], for example triggering:

      Let's make huge_pte_lockptr() effectively use the same PT locks as any
      core-mm page table walker would.  Add ptep_lockptr() to obtain the PTE
      page table lock using a pte pointer -- unfortunately we cannot convert
      pte_lockptr() because virt_to_page() doesn't work with kmap'ed page tables
      we can have with CONFIG_HIGHPTE.
      
      Handle CONFIG_PGTABLE_LEVELS correctly by checking in reverse order, such
      that when e.g., CONFIG_PGTABLE_LEVELS==2 with
      PGDIR_SIZE==P4D_SIZE==PUD_SIZE==PMD_SIZE will work as expected.  Document
      why that works.
      
      There is one ugly case: powerpc 8xx, whereby we have an 8 MiB hugetlb
      folio being mapped using two PTE page tables.  While hugetlb wants to take
      the PMD table lock, core-mm would grab the PTE table lock of one of both
      PTE page tables.  In such corner cases, we have to make sure that both
      locks match, which is (fortunately!) currently guaranteed for 8xx as it
      does not support SMP and consequently doesn't use split PT locks.

      mseal: fix is_madv_discard() · e46bc2e7
      Pedro Falcato authored
      is_madv_discard did its check wrong. MADV_ flags are not bitwise,
      they're normal sequential numbers. So, for instance:
      	behavior & (/* ... */ | MADV_REMOVE)
      
      tagged both MADV_REMOVE and MADV_RANDOM (bit 0 set) as discard
      operations.
      
      As a result the kernel could erroneously block certain madvises (e.g
      MADV_RANDOM or MADV_HUGEPAGE) on sealed VMAs due to them sharing bits
      with blocked MADV operations (e.g REMOVE or WIPEONFORK).
      
      This is obviously incorrect, so use a switch statement instead.

      Pull x86 fixes from Thomas Gleixner:
      
       - Fix 32-bit PTI for real.
      
         pti_clone_entry_text() is called twice, once before initcalls so that
         initcalls can use the user-mode helper and then again after text is
         set read only. Setting read only on 32-bit might break up the PMD
         mapping, which makes the second invocation of pti_clone_entry_text()
         find the mappings out of sync and failing.
      
         Allow the second call to split the existing PMDs in the user mapping
         and synchronize with the kernel mapping.
      
       - Don't make acpi_mp_wake_mailbox read-only after init as the mail box
         must be writable in the case that CPU hotplug operations happen after
         boot. Otherwise the attempt to start a CPU crashes with a write to
         read only memory.
      
       - Add a missing sanity check in mtrr_save_state() to ensure that the
         fixed MTRR MSRs are supported.
      
         Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but
         the WARN_ON() can bring systems down when panic on warn is set.

      Pull time keeping fixes from Thomas Gleixner:
      
       - Fix a couple of issues in the NTP code where user supplied values are
         neither sanity checked nor clamped to the operating range. This
         results in integer overflows and eventualy NTP getting out of sync.
      
         According to the history the sanity checks had been removed in favor
         of clamping the values, but the clamping never worked correctly under
         all circumstances. The NTP people asked to not bring the sanity
         checks back as it might break existing applications.
      
         Make the clamping work correctly and add it where it's missing
      
       - If adjtimex() sets the clock it has to trigger the hrtimer subsystem
         so it can adjust and if the clock was set into the future expire
         timers if needed. The caller should provide a bitmask to tell
         hrtimers which clocks have been adjusted.
      
         adjtimex() uses not the proper constant and uses CLOCK_REALTIME
         instead, which is 0. So hrtimers adjusts only the clocks, but does
         not check for expired timers, which might make them expire really
         late. Use the proper bitmask constant instead.

      bcachefs_metadata_version_disk_accounting_v2 erroneously had padding
      bytes in disk_accounting_key, which is a problem because we have to
      guarantee that all unused bytes in disk_accounting_key are zeroed.
      
      Fortunately 6.11 isn't out yet, so it's cheap to fix this by spinning a

      module: make waiting for a concurrent module loader interruptible · 2124d84d
      Linus Torvalds authored
      The recursive aes-arm-bs module load situation reported by Russell King
      is getting fixed in the crypto layer, but this in the meantime fixes the
      "recursive load hangs forever" by just making the waiting for the first
      module load be interruptible.
      
      This should now match the old behavior before commit 9b9879fc
      ("modules: catch concurrent module loads, treat them as idempotent"),
      which used the different "wait for module to be ready" code in
      module_patient_check_exists().
      
      End result: a recursive module load will still block, but now a signal
      will interrupt it and fail the second module load, at which point the
      first module will successfully complete loading.
      
      Fixes: 9b9879fc ("modules: catch concurrent module loads, treat them as idempotent")

      Two fixes on the Qualcomm GENI I2C controller are cleaning up the
      error exit patch in the runtime_resume() function. The first is
      disabling the clock, the second disables the icc on the way out.

      ASoC: Fixes for v6.11
      
      Quite a lot of fixes have come in since the merge window, there's some
      repetitive fixes over the Qualcomm drivers increasing the patch count,
      along with a large batch of fixes from Cirrus.  We also have some quirks
      and some individual fixes.
