included in this merge do the following:
 
 - Kemeng Shi has contributed some compation maintenance work in the
   series "Fixes and cleanups to compaction".
 
 - Joel Fernandes has a patchset ("Optimize mremap during mutual
   alignment within PMD") which fixes an obscure issue with mremap()'s
   pagetable handling during a subsequent exec(), based upon an
   implementation which Linus suggested.
 
 - More DAMON/DAMOS maintenance and feature work from SeongJae Park i the
   following patch series:
 
 	mm/damon: misc fixups for documents, comments and its tracepoint

   provides some fixups for the recently-added "unaccepted memory' feature.
   To increase the feature's checking coverage.  "Plug a few gaps where
   RAM is exposed without checking if it is unaccepted memory".
 
 - In the series "cleanups for lockless slab shrink" Qi Zheng has done
   some maintenance work which is preparation for the lockless slab
   shrinking code.
 
 - Qi Zheng has redone the earlier (and reverted) attempt to make slab
   shrinking lockless in the series "use refcount+RCU method to implement
   lockless slab shrink".

   in the series "Anon rmap cleanups".
 
 - Kefeng Wang does more folio conversions and some maintenance work in
   the migration code.  Series "mm: migrate: more folio conversion and
   unification".

   causing long stalls under some heavy memory/IO loads.  Some cleanups
   were added on the way.  Series "Add and use bdev_getblk()".
 
 - In the series "Use nth_page() in place of direct struct page
   manipulation" Zi Yan has fixed a potential issue with the direct
   manipulation of hugetlb page frames.
 
 - In the series "mm: hugetlb: Skip initialization of gigantic tail
   struct pages if freed by HVO" has improved our handling of gigantic
   pages in the hugetlb vmmemmep optimizaton code.  This provides

     definition (Ilpo Järvinen)

   - Simplify config access error checking in various drivers (Ilpo
     Järvinen)

   - Use pcie_capability_clear_word() (not
     pcie_capability_clear_and_set_word()) when only clearing (Ilpo
     Järvinen)

   - Add pci_get_base_class() to simplify finding devices using base
     class only (ignoring subclass and programming interface) (Sui

     devices from before the Class Code was added to PCI (Sui Jingfeng)

   - Use pci_is_vga() for vgaarb, sysfs "boot_vga", virtio, qxl to
     include ancient VGA devices (Sui Jingfeng)

  Resource management:

   - Make pci_assign_unassigned_resources() non-init because sparc uses
     it after init (Randy Dunlap)

  Driver binding:

   - Retain .remove() and .probe() callbacks (previously __init) because
     sysfs may cause them to be called later (Uwe Kleine-König)

   - Prevent xHCI driver from claiming AMD VanGogh USB3 DRD device, so
     it can be claimed by dwc3 instead (Vicki Pfau)

  PCI device hotplug:

   - Add Ampere Altra Attention Indicator extension driver for acpiphp
     (D Scott Phillips)

  Power management:

   - Quirk VideoPropulsion Torrent QN16e with longer delay after reset

   - Prevent users from overriding drivers that say we shouldn't use
     D3cold (Lukas Wunner)

   - Avoid PME from D3hot/D3cold for AMD Rembrandt and Phoenix USB4
     because wakeup interrupts from those states don't work if amd-pmc
     has put the platform in a hardware sleep state (Mario Limonciello)

  IOMMU:

   - Disable ATS for Intel IPU E2000 devices with invalidation message
     endianness erratum (Bartosz Pawlowski)

  Error handling:

   - Factor out interrupt enable/disable into helpers (Kai-Heng Feng)

  Peer-to-peer DMA:

   - Fix flexible-array usage in struct pci_p2pdma_pagemap in case we
     ever use pagemaps with multiple entries (Gustavo A. R. Silva)

  Microsoft Hyper-V host bridge driver:

   - Annotate struct hv_dr_state with __counted_by (Kees Cook)

  NVIDIA Tegra194 PCIe controller driver:

   - Drop setting of LNKCAP_MLW (max link width) since dw_pcie_setup()
     already does this via dw_pcie_link_set_max_link_width() (Yoshihiro
     Shimoda)

  Qualcomm PCIe controller driver:

   - Use PCIE_SPEED2MBS_ENC() to simplify encoding of link speed
     (Manivannan Sadhasivam)

   - Add a .write_dbi2() callback so DBI2 register writes, e.g., for
     setting the BAR size, work correctly (Manivannan Sadhasivam)

   - Enable ASPM for platforms that use 1.9.0 ops, because the PCI core
     doesn't enable ASPM states that haven't been enabled by the
     firmware (Manivannan Sadhasivam)

  Renesas R-Car Gen4 PCIe controller driver:

   - Add DesignWare core support (set max link width, EDMA_UNROLL flag,
     .pre_init(), .deinit(), etc) for use by R-Car Gen4 driver
     (Yoshihiro Shimoda)

   - Add driver and DT schema for DesignWare-based Renesas R-Car Gen4
     controller in both host and endpoint mode (Yoshihiro Shimoda)

  Xilinx NWL PCIe controller driver:

   - Update ECAM size to support 256 buses (Thippeswamy Havalige)

   - Stop setting bridge primary/secondary/subordinate bus numbers,
     since PCI core does this (Thippeswamy Havalige)

  Xilinx XDMA controller driver:

   - Add driver and DT schema for Zynq UltraScale+ MPSoCs devices with
     Xilinx XDMA Soft IP (Thippeswamy Havalige)

  Miscellaneous:

   - Use FIELD_GET()/FIELD_PREP() to simplify and reduce use of _SHIFT
     macros (Ilpo Järvinen, Bjorn Helgaas)

   - Remove logic_outb(), _outw(), outl() duplicate declarations (John
     Sanpe)

   - Replace unnecessary UTF-8 in Kconfig help text because menuconfig
     doesn't render it correctly (Liu Song)"

426ee5196d sysctl-6.7-rc1
To help make the move of sysctls out of kernel/sysctl.c not incur a size
 penalty sysctl has been changed to allow us to not require the sentinel, the
 final empty element on the sysctl array. Joel Granados has been doing all this
 work. On the v6.6 kernel we got the major infrastructure changes required to
 support this. For v6.7-rc1 we have all arch/ and drivers/ modified to remove
 the sentinel. Both arch and driver changes have been on linux-next for a bit
 less than a month. It is worth re-iterating the value:
 
   - this helps reduce the overall build time size of the kernel and run time
      memory consumed by the kernel by about ~64 bytes per array
   - the extra 64-byte penalty is no longer inncurred now when we move sysctls
     out from kernel/sysctl.c to their own files
 
 For v6.8-rc1 expect removal of all the sentinels and also then the unneeded
 check for procname == NULL.
 
 The last 2 patches are fixes recently merged by Krister Johansen which allow
 us again to use softlockup_panic early on boot. This used to work but the
 alias work broke it. This is useful for folks who want to detect softlockups
 super early rather than wait and spend money on cloud solutions with nothing
 but an eventual hung kernel. Although this hadn't gone through linux-next it's
 also a stable fix, so we might as well roll through the fixes now.

Merge tag 'sysctl-6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux

Pull sysctl updates from Luis Chamberlain:
 "To help make the move of sysctls out of kernel/sysctl.c not incur a
  size penalty sysctl has been changed to allow us to not require the
  sentinel, the final empty element on the sysctl array. Joel Granados
  has been doing all this work. On the v6.6 kernel we got the major
  infrastructure changes required to support this. For v6.7-rc1 we have
  all arch/ and drivers/ modified to remove the sentinel. Both arch and
  driver changes have been on linux-next for a bit less than a month. It
  is worth re-iterating the value:

   - this helps reduce the overall build time size of the kernel and run
     time memory consumed by the kernel by about ~64 bytes per array

   - the extra 64-byte penalty is no longer inncurred now when we move
     sysctls out from kernel/sysctl.c to their own files

  For v6.8-rc1 expect removal of all the sentinels and also then the
  unneeded check for procname == NULL.

  The last two patches are fixes recently merged by Krister Johansen
  which allow us again to use softlockup_panic early on boot. This used
  to work but the alias work broke it. This is useful for folks who want
  to detect softlockups super early rather than wait and spend money on
  cloud solutions with nothing but an eventual hung kernel. Although
  this hadn't gone through linux-next it's also a stable fix, so we
  might as well roll through the fixes now"

1e0c505e13 asm-generic updates for v6.7
The ia64 architecture gets its well-earned retirement as planned,
 now that there is one last (mostly) working release that will
 be maintained as an LTS kernel.
 
 The architecture specific system call tables are updated for
 the added map_shadow_stack() syscall and to remove references
 to the long-gone sys_lookup_dcookie() syscall.

deefd5024f VFIO updates for v6.7
- Add support for "chunk mode" in the mlx5-vfio-pci variant driver,
    which allows both larger device image sizes for migration, beyond
    the previous 4GB limit, and also read-ahead support for improved
    migration performance. (Yishai Hadas)
 
  - A new bus master control interface for the CDX bus driver where
    there is no in-band mechanism to toggle device DMA as there is
    through config space on PCI devices. (Nipun Gupta)
 
  - Add explicit alignment directives to vfio data structures to
    reduce the chance of breaking 32-bit userspace.  In most cases
    this is transparent and the remaining cases where data structures
    are padded work within the existing rules for extending data
    structures within vfio.  (Stefan Hajnoczi)
 
  - Resolve a bug in the cdx bus driver noted when compiled with clang
    where missing parenthesis result in the wrong operation.
    (Nathan Chancellor)
 
  - Resolve errors reported by smatch for a function when dealing
    with invalid inputs. (Alex Williamson)
 
  - Add migration support to the mtty vfio/mdev sample driver for
    testing and integration purposes, allowing CI of migration without
    specific hardware requirements.  Also resolve many of the short-
    comings of this driver relative to implementation of the vfio
    interrupt ioctl along the way. (Alex Williamson)

eb55307e67 X86 core code updates:
- Limit the hardcoded topology quirk for Hygon CPUs to those which have a
     model ID less than 4. The newer models have the topology CPUID leaf 0xB
     correctly implemented and are not affected.
 
   - Make SMT control more robust against enumeration failures
 
     SMT control was added to allow controlling SMT at boottime or
     runtime. The primary purpose was to provide a simple mechanism to
     disable SMT in the light of speculation attack vectors.
 
     It turned out that the code is sensible to enumeration failures and
     worked only by chance for XEN/PV. XEN/PV has no real APIC enumeration
     which means the primary thread mask is not set up correctly. By chance
     a XEN/PV boot ends up with smp_num_siblings == 2, which makes the
     hotplug control stay at its default value "enabled". So the mask is
     never evaluated.
 
     The ongoing rework of the topology evaluation caused XEN/PV to end up
     with smp_num_siblings == 1, which sets the SMT control to "not
     supported" and the empty primary thread mask causes the hotplug core to
     deny the bringup of the APS.
 
     Make the decision logic more robust and take 'not supported' and 'not
     implemented' into account for the decision whether a CPU should be
     booted or not.
 
   - Fake primary thread mask for XEN/PV
 
     Pretend that all XEN/PV vCPUs are primary threads, which makes the
     usage of the primary thread mask valid on XEN/PV. That is consistent
     with because all of the topology information on XEN/PV is fake or even
     non-existent.
 
   - Encapsulate topology information in cpuinfo_x86
 
     Move the randomly scattered topology data into a separate data
     structure for readability and as a preparatory step for the topology
     evaluation overhaul.
 
   - Consolidate APIC ID data type to u32
 
     It's fixed width hardware data and not randomly u16, int, unsigned long
     or whatever developers decided to use.
 
   - Cure the abuse of cpuinfo for persisting logical IDs.
 
     Per CPU cpuinfo is used to persist the logical package and die
     IDs. That's really not the right place simply because cpuinfo is
     subject to be reinitialized when a CPU goes through an offline/online
     cycle.
 
     Use separate per CPU data for the persisting to enable the further
     topology management rework. It will be removed once the new topology
     management is in place.
 
   - Provide a debug interface for inspecting topology information
 
     Useful in general and extremly helpful for validating the topology
     management rework in terms of correctness or "bug" compatibility.

Merge tag 'vfs-6.7.misc' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs

Pull misc vfs updates from Christian Brauner:
 "This contains the usual miscellaneous features, cleanups, and fixes
  for vfs and individual fses.

  Features:

   - Rename and export helpers that get write access to a mount. They
     are used in overlayfs to get write access to the upper mount.

   - Print the pretty name of the root device on boot failure. This
     helps in scenarios where we would usually only print
     "unknown-block(1,2)".

   - Add an internal SB_I_NOUMASK flag. This is another part in the
     endless POSIX ACL saga in a way.

     When POSIX ACLs are enabled via SB_POSIXACL the vfs cannot strip
     the umask because if the relevant inode has POSIX ACLs set it might
     take the umask from there. But if the inode doesn't have any POSIX
     ACLs set then we apply the umask in the filesytem itself. So we end
     up with:

      (1) no SB_POSIXACL -> strip umask in vfs
      (2) SB_POSIXACL    -> strip umask in filesystem

     The umask semantics associated with SB_POSIXACL allowed filesystems
     that don't even support POSIX ACLs at all to raise SB_POSIXACL
     purely to avoid umask stripping. That specifically means NFS v4 and
     Overlayfs. NFS v4 does it because it delegates this to the server
     and Overlayfs because it needs to delegate umask stripping to the
     upper filesystem, i.e., the filesystem used as the writable layer.

     This went so far that SB_POSIXACL is raised eve on kernels that
     don't even have POSIX ACL support at all.

     Stop this blatant abuse and add SB_I_NOUMASK which is an internal
     superblock flag that filesystems can raise to opt out of umask
     handling. That should really only be the two mentioned above. It's
     not that we want any filesystems to do this. Ideally we have all
     umask handling always in the vfs.

   - Make overlayfs use SB_I_NOUMASK too.

   - Now that we have SB_I_NOUMASK, stop checking for SB_POSIXACL in
     IS_POSIXACL() if the kernel doesn't have support for it. This is a
     very old patch but it's only possible to do this now with the wider
     cleanup that was done.

   - Follow-up work on fake path handling from last cycle. Citing mostly
     from Amir:

     When overlayfs was first merged, overlayfs files of regular files
     and directories, the ones that are installed in file table, had a
     "fake" path, namely, f_path is the overlayfs path and f_inode is
     the "real" inode on the underlying filesystem.

     In v6.5, we took another small step by introducing of the
     backing_file container and the file_real_path() helper. This change
     allowed vfs and filesystem code to get the "real" path of an
     overlayfs backing file. With this change, we were able to make
     fsnotify work correctly and report events on the "real" filesystem
     objects that were accessed via overlayfs.

     This method works fine, but it still leaves the vfs vulnerable to
     new code that is not aware of files with fake path. A recent
     example is commit db1d1e8b98 ("IMA: use vfs_getattr_nosec to get
     the i_version"). This commit uses direct referencing to f_path in
     IMA code that otherwise uses file_inode() and file_dentry() to
     reference the filesystem objects that it is measuring.

     This contains work to switch things around: instead of having
     filesystem code opt-in to get the "real" path, have generic code
     opt-in for the "fake" path in the few places that it is needed.

     Is it far more likely that new filesystems code that does not use
     the file_dentry() and file_real_path() helpers will end up causing
     crashes or averting LSM/audit rules if we keep the "fake" path
     exposed by default.

     This change already makes file_dentry() moot, but for now we did
     not change this helper just added a WARN_ON() in ovl_d_real() to
     catch if we have made any wrong assumptions.

     After the dust settles on this change, we can make file_dentry() a
     plain accessor and we can drop the inode argument to ->d_real().

   - Switch struct file to SLAB_TYPESAFE_BY_RCU. This looks like a small
     change but it really isn't and I would like to see everyone on
     their tippie toes for any possible bugs from this work.

     Essentially we've been doing most of what SLAB_TYPESAFE_BY_RCU for
     files since a very long time because of the nasty interactions
     between the SCM_RIGHTS file descriptor garbage collection. So
     extending it makes a lot of sense but it is a subtle change. There
     are almost no places that fiddle with file rcu semantics directly
     and the ones that did mess around with struct file internal under
     rcu have been made to stop doing that because it really was always
     dodgy.

     I forgot to put in the link tag for this change and the discussion
     in the commit so adding it into the merge message:

       https://lore.kernel.org/r/20230926162228.68666-1-mjguzik@gmail.com

  Cleanups:

   - Various smaller pipe cleanups including the removal of a spin lock
     that was only used to protect against writes without pipe_lock()
     from O_NOTIFICATION_PIPE aka watch queues. As that was never
     implemented remove the additional locking from pipe_write().

   - Annotate struct watch_filter with the new __counted_by attribute.

   - Clarify do_unlinkat() cleanup so that it doesn't look like an extra
     iput() is done that would cause issues.

   - Simplify file cleanup when the file has never been opened.

   - Use module helper instead of open-coding it.

   - Predict error unlikely for stale retry.

   - Use WRITE_ONCE() for mount expiry field instead of just commenting
     that one hopes the compiler doesn't get smart.

  Fixes:

   - Fix readahead on block devices.

   - Fix writeback when layztime is enabled and inodes whose timestamp
     is the only thing that changed reside on wb->b_dirty_time. This
     caused excessively large zombie memory cgroup when lazytime was
     enabled as such inodes weren't handled fast enough.

   - Convert BUG_ON() to WARN_ON_ONCE() in open_last_lookups()"

On NUMA systems, local memory gets the local mtype, set by an
override callback. If EXT_COHERENT is set, memory will be set as
MTYPE_UC by default, with local memory MTYPE_CC.

Add an option in the override function for this case, and
add a check to ensure it is not used on UNCACHED memory.

V2: Combined APU and NUMA code into one patch
V3: Fixed a potential nullptr in amdgpu_vm_bo_update

1efdd37cc0 drm/amd/display: fix S/G display enablement
An assignment statement was reversed during a refactor which effectively
disabled S/G display outright. Since, we use
adev->mode_info.gpu_vm_support to indicate to the rest of the driver
that S/G display should be enabled and currently it is always set to
false. So, to fix this set adev->mode_info.gpu_vm_support's value to
that of init_data.flags.gpu_vm_support (and not vice versa).
