     deref of tracking profiles in when in complain mode

  Cleanups:
   - Remove everything being reported as deadcode
   - replace misleading 'scrubbing environment' phrase in debug print
   - Remove unnecessary NULL check before kvfree()
   - clean up duplicated parts of handle_onexec()

After the deprecation of CONFIG_DEFAULT_SECURITY, it is no longer used
to enable and configure AppArmor. Since kernel 5.0,
`CONFIG_SECURITY_APPARMOR_BOOTPARAM_VALUE` is not used either.
Instead, the CONFIG_LSM parameter manages the order and selection of LSMs.

Pull PCI updates from Bjorn Helgaas:
 "Enumeration:

   - Make pci_stop_dev() and pci_destroy_dev() safe so concurrent
     callers can't stop a device multiple times, even as we migrate from
     the global pci_rescan_remove_lock to finer-grained locking (Keith
     Busch)

   - Improve pci_walk_bus() implementation by making it recursive and
     moving locking up to avoid need for a 'locked' parameter (Keith
     Busch)

   - Unexport pci_walk_bus_locked(), which is only used internally by
     the PCI core (Keith Busch)

   - Detect some Thunderbolt chips that are built-in and hence
     'trustworthy' by a heuristic since the 'ExternalFacingPort' and
     'usb4-host-interface' ACPI properties are not quite enough (Esther
     Shimanovich)

  Resource management:

   - Use PCI bus addresses (not CPU addresses) in 'ranges' properties
     when building dynamic DT nodes so systems where PCI and CPU
     addresses differ work correctly (Andrea della Porta)

   - Tidy resource sizing and assignment with helpers to reduce
     redundancy (Ilpo Järvinen)

   - Improve pdev_sort_resources() 'bogus alignment' warning to be more
     specific (Ilpo Järvinen)

  Driver binding:

   - Convert driver .remove_new() callbacks to .remove() again to finish
     the conversion from returning 'int' to being 'void' (Sergio
     Paracuellos)

   - Export pcim_request_all_regions(), a managed interface to request
     all BARs (Philipp Stanner)

   - Replace pcim_iomap_regions_request_all() with
     pcim_request_all_regions(), and pcim_iomap_table()[n] with
     pcim_iomap(n), in the following drivers: ahci, crypto qat, crypto
     octeontx2, intel_th, iwlwifi, ntb idt, serial rp2, ALSA korg1212
     (Philipp Stanner)

   - Remove the now unused pcim_iomap_regions_request_all() (Philipp
     Stanner)

   - Export pcim_iounmap_region(), a managed interface to unmap and
     release a PCI BAR (Philipp Stanner)

   - Replace pcim_iomap_regions(mask) with pcim_iomap_region(n), and
     pcim_iounmap_regions(mask) with pcim_iounmap_region(n), in the
     following drivers: fpga dfl-pci, block mtip32xx, gpio-merrifield,
     cavium (Philipp Stanner)

  Error handling:

   - Add sysfs 'reset_subordinate' to reset the entire hierarchy below a
     bridge; previously Secondary Bus Reset could only be used when
     there was a single device below a bridge (Keith Busch)

   - Warn if we reset a running device where the driver didn't register
     pci_error_handlers notification callbacks (Keith Busch)

  ASPM:

   - Disable ASPM L1 before touching L1 PM Substates to follow the spec
     closer and avoid a CPU load timeout on some platforms (Ajay
     Agarwal)

   - Set devices below Intel VMD to D0 before enabling ASPM L1 Substates
     as required per spec for all L1 Substates changes (Jian-Hong Pan)

  Power management:

   - Enable starfive controller runtime PM before probing host bridge
     (Mayank Rana)

   - Enable runtime power management for host bridges (Krishna chaitanya
     chundru)

  Power control:

   - Use of_platform_device_create() instead of of_platform_populate()
     to create pwrctl platform devices so we can control it based on the
     child nodes (Manivannan Sadhasivam)

   - Create pwrctrl platform devices only if there's a relevant power
     supply property (Manivannan Sadhasivam)

   - Add device link from the pwrctl supplier to the PCI dev to ensure
     pwrctl drivers are probed before the PCI dev driver; this avoids a
     race where pwrctl could change device power state while the PCI
     driver was active (Manivannan Sadhasivam)

   - Find pwrctl device for removal with of_find_device_by_node()
     instead of searching all children of the parent (Manivannan
     Sadhasivam)

   - Rename 'pwrctl' to 'pwrctrl' to match new bandwidth controller
     ('bwctrl') and hotplug files (Bjorn Helgaas)

  Bandwidth control:

   - Add read/modify/write locking for Link Control 2, which is used to
     manage Link speed (Ilpo Järvinen)

   - Extract Link Bandwidth Management Status check into
     pcie_lbms_seen(), where it can be shared between the bandwidth
     controller and quirks that use it to help retrain failed links
     (Ilpo Järvinen)

   - Re-add Link Bandwidth notification support with updates to address
     the reasons it was previously reverted (Alexandru Gagniuc, Ilpo
     Järvinen)

   - Add pcie_set_target_speed() and related functionality so drivers
     can manage PCIe Link speed based on thermal or other constraints
     (Ilpo Järvinen)

   - Add a thermal cooling driver to throttle PCIe Links via the
     existing thermal management framework (Ilpo Järvinen)

   - Add a userspace selftest for the PCIe bandwidth controller (Ilpo
     Järvinen)

  PCI device hotplug:

   - Add hotplug controller driver for Marvell OCTEON multi-function
     device where function 0 has a management console interface to
     enable/disable and provision various personalities for the other
     functions (Shijith Thotton)

   - Retain a reference to the pci_bus for the lifetime of a pci_slot to
     avoid a use-after-free when the thunderbolt driver resets USB4 host
     routers on boot, causing hotplug remove/add of downstream docks or
     other devices (Lukas Wunner)

   - Remove unused cpcihp struct cpci_hp_controller_ops.hardware_test
     (Guilherme Giacomo Simoes)

   - Remove unused cpqphp struct ctrl_dbg.ctrl (Christophe JAILLET)

   - Use pci_bus_read_dev_vendor_id() instead of hand-coded presence
     detection in cpqphp (Ilpo Järvinen)

   - Simplify cpqphp enumeration, which is already simple-minded and
     doesn't handle devices below hot-added bridges (Ilpo Järvinen)

  Virtualization:

   - Add ACS quirk for Wangxun FF5xxx NICs, which don't advertise an ACS
     capability but do isolate functions as though PCI_ACS_RR and
     PCI_ACS_CR were set, so the functions can be in independent IOMMU
     groups (Mengyuan Lou)

  TLP Processing Hints (TPH):

   - Add and document TLP Processing Hints (TPH) support so drivers can
     enable and disable TPH and the kernel can save/restore TPH
     configuration (Wei Huang)

   - Add TPH Steering Tag support so drivers can retrieve Steering Tag
     values associated with specific CPUs via an ACPI _DSM to improve
     performance by directing DMA writes closer to their consumers (Wei
     Huang)

  Data Object Exchange (DOE):

   - Wait up to 1 second for DOE Busy bit to clear before writing a
     request to the mailbox to avoid failures if the mailbox is still
     busy from a previous transfer (Gregory Price)

  Endpoint framework:

   - Skip attempts to allocate from endpoint controller memory window if
     the requested size is larger than the window (Damien Le Moal)

   - Add and document pci_epc_mem_map() and pci_epc_mem_unmap() to
     handle controller-specific size and alignment constraints, and add
     test cases to the endpoint test driver (Damien Le Moal)

   - Implement dwc pci_epc_ops.align_addr() so pci_epc_mem_map() can
     observe DWC-specific alignment requirements (Damien Le Moal)

   - Synchronously cancel command handler work in endpoint test before
     cleaning up DMA and BARs (Damien Le Moal)

   - Respect endpoint page size in dw_pcie_ep_align_addr() (Niklas
     Cassel)

   - Use dw_pcie_ep_align_addr() in dw_pcie_ep_raise_msi_irq() and
     dw_pcie_ep_raise_msix_irq() instead of open coding the equivalent
     (Niklas Cassel)

   - Avoid NULL dereference if Modem Host Interface Endpoint lacks
     'mmio' DT property (Zhongqiu Han)

   - Release PCI domain ID of Endpoint controller parent (not controller
     itself) and before unregistering the controller, to avoid
     use-after-free (Zijun Hu)

   - Clear secondary (not primary) EPC in pci_epc_remove_epf() when
     removing the secondary controller associated with an NTB (Zijun Hu)

  Cadence PCIe controller driver:

   - Lower severity of 'phy-names' message (Bartosz Wawrzyniak)

  Freescale i.MX6 PCIe controller driver:

   - Fix suspend/resume support on i.MX6QDL, which has a hardware
     erratum that prevents use of L2 (Stefan Eichenberger)

  Intel VMD host bridge driver:

   - Add 0xb60b and 0xb06f Device IDs for client SKUs (Nirmal Patel)

  MediaTek PCIe Gen3 controller driver:

   - Update mediatek-gen3 DT binding to require the exact number of
     clocks for each SoC (Fei Shao)

   - Add support for DT 'max-link-speed' and 'num-lanes' properties to
     restrict the link speed and width (AngeloGioacchino Del Regno)

  Microchip PolarFlare PCIe controller driver:

   - Add DT and driver support for using either of the two PolarFire
     Root Ports (Conor Dooley)

  NVIDIA Tegra194 PCIe controller driver:

   - Move endpoint controller cleanups that depend on refclk from the
     host to the notifier that tells us the host has deasserted PERST#,
     when refclk should be valid (Manivannan Sadhasivam)

  Qualcomm PCIe controller driver:

   - Add qcom SAR2130P DT binding with an additional clock (Dmitry
     Baryshkov)

   - Enable MSI interrupts if 'global' IRQ is supported, since a
     previous commit unintentionally masked them (Manivannan Sadhasivam)

   - Move endpoint controller cleanups that depend on refclk from the
     host to the notifier that tells us the host has deasserted PERST#,
     when refclk should be valid (Manivannan Sadhasivam)

   - Add DT binding and driver support for IPQ9574, with Synopsys IP
     v5.80a and Qcom IP 1.27.0 (devi priya)

   - Move the OPP "operating-points-v2" table from the
     qcom,pcie-sm8450.yaml DT binding to qcom,pcie-common.yaml, where it
     can be used by other Qcom platforms (Qiang Yu)

   - Add 'global' SPI interrupt for events like link-up, link-down to
     qcom,pcie-x1e80100 DT binding so we can start enumeration when the
     link comes up (Qiang Yu)

   - Disable ASPM L0s for qcom,pcie-x1e80100 since the PHY is not tuned
     to support this (Qiang Yu)

   - Add ops_1_21_0 for SC8280X family SoC, which doesn't use the
     'iommu-map' DT property and doesn't need BDF-to-SID translation
     (Qiang Yu)

  Rockchip PCIe controller driver:

   - Define ROCKCHIP_PCIE_AT_SIZE_ALIGN to replace magic 256 endpoint
     .align value (Damien Le Moal)

   - When unmapping an endpoint window, compute the region index instead
     of searching for it, and verify that the address was mapped (Damien
     Le Moal)

   - When mapping an endpoint window, verify that the address hasn't
     been mapped already (Damien Le Moal)

   - Implement pci_epc_ops.align_addr() for rockchip-ep (Damien Le Moal)

   - Fix MSI IRQ data mapping to observe the alignment constraint, which
     fixes intermittent page faults in memcpy_toio() and memcpy_fromio()
     (Damien Le Moal)

   - Rename rockchip_pcie_parse_ep_dt() to
     rockchip_pcie_ep_get_resources() for consistency with similar DT
     interfaces (Damien Le Moal)

   - Skip the unnecessary link train in rockchip_pcie_ep_probe() and do
     it only in the endpoint start operation (Damien Le Moal)

   - Implement pci_epc_ops.stop_link() to disable link training and
     controller configuration (Damien Le Moal)

   - Attempt link training at 5 GT/s when both partners support it
     (Damien Le Moal)

   - Add a handler for PERST# signal so we can detect host-initiated
     resets and start link training after PERST# is deasserted (Damien
     Le Moal)

  Synopsys DesignWare PCIe controller driver:

   - Clear outbound address on unmap so dw_pcie_find_index() won't match
     an ATU index that was already unmapped (Damien Le Moal)

   - Use of_property_present() instead of of_property_read_bool() when
     testing for presence of non-boolean DT properties (Rob Herring)

   - Advertise 1MB size if endpoint supports Resizable BARs, which was
     inadvertently lost in v6.11 (Niklas Cassel)

  TI J721E PCIe driver:

   - Add PCIe support for J722S SoC (Siddharth Vadapalli)

   - Delay PCIE_T_PVPERL_MS (100 ms), not just PCIE_T_PERST_CLK_US (100
     us), before deasserting PERST# to ensure power and refclk are
     stable (Siddharth Vadapalli)

  TI Keystone PCIe controller driver:

   - Set the 'ti,keystone-pcie' mode so v3.65a devices work in Root
     Complex mode (Kishon Vijay Abraham I)

   - Try to avoid unrecoverable SError for attempts to issue config
     transactions when the link is down; this is racy but the best we
     can do (Kishon Vijay Abraham I)

  Miscellaneous:

   - Reorganize kerneldoc parameter names to match order in function
     signature (Julia Lawall)

   - Fix sysfs reset_method_store() memory leak (Todd Kjos)

   - Simplify pci_create_slot() (Ilpo Järvinen)

   - Fix incorrect printf format specifiers in pcitest (Luo Yifan)"

Pull slab updates from Vlastimil Babka:

 - Add new slab_strict_numa boot parameter to enforce per-object memory
   policies on top of slab folio policies, for systems where saving cost
   of remote accesses is more important than minimizing slab allocation
   overhead (Christoph Lameter)

 - Fix for freeptr_offset alignment check being too strict for m68k
   (Geert Uytterhoeven)

 - krealloc() fixes for not violating __GFP_ZERO guarantees on
   krealloc() when slub_debug (redzone and object tracking) is enabled
   (Feng Tang)

 - Fix a memory leak in case sysfs registration fails for a slab cache,
   and also no longer fail to create the cache in that case (Hyeonggon
   Yoo)

 - Fix handling of detected consistency problems (due to buggy slab
   user) with slub_debug enabled, so that it does not cause further list
   corruption bugs (yuan.gao)

 - Code cleanup and kerneldocs polishing (Zhen Lei, Vlastimil Babka)

Pull MM updates from Andrew Morton:

 - The series "zram: optimal post-processing target selection" from
   Sergey Senozhatsky improves zram's post-processing selection
   algorithm. This leads to improved memory savings.

 - Wei Yang has gone to town on the mapletree code, contributing several
   series which clean up the implementation:
	- "refine mas_mab_cp()"
	- "Reduce the space to be cleared for maple_big_node"
	- "maple_tree: simplify mas_push_node()"
	- "Following cleanup after introduce mas_wr_store_type()"
	- "refine storing null"

 - The series "selftests/mm: hugetlb_fault_after_madv improvements" from
   David Hildenbrand fixes this selftest for s390.

 - The series "introduce pte_offset_map_{ro|rw}_nolock()" from Qi Zheng
   implements some rationaizations and cleanups in the page mapping
   code.

 - The series "mm: optimize shadow entries removal" from Shakeel Butt
   optimizes the file truncation code by speeding up the handling of
   shadow entries.

 - The series "Remove PageKsm()" from Matthew Wilcox completes the
   migration of this flag over to being a folio-based flag.

 - The series "Unify hugetlb into arch_get_unmapped_area functions" from
   Oscar Salvador implements a bunch of consolidations and cleanups in
   the hugetlb code.

 - The series "Do not shatter hugezeropage on wp-fault" from Dev Jain
   takes away the wp-fault time practice of turning a huge zero page
   into small pages. Instead we replace the whole thing with a THP. More
   consistent cleaner and potentiall saves a large number of pagefaults.

 - The series "percpu: Add a test case and fix for clang" from Andy
   Shevchenko enhances and fixes the kernel's built in percpu test code.

 - The series "mm/mremap: Remove extra vma tree walk" from Liam Howlett
   optimizes mremap() by avoiding doing things which we didn't need to
   do.

 - The series "Improve the tmpfs large folio read performance" from
   Baolin Wang teaches tmpfs to copy data into userspace at the folio
   size rather than as individual pages. A 20% speedup was observed.

 - The series "mm/damon/vaddr: Fix issue in
   damon_va_evenly_split_region()" fro Zheng Yejian fixes DAMON
   splitting.

 - The series "memcg-v1: fully deprecate charge moving" from Shakeel
   Butt removes the long-deprecated memcgv2 charge moving feature.

 - The series "fix error handling in mmap_region() and refactor" from
   Lorenzo Stoakes cleanup up some of the mmap() error handling and
   addresses some potential performance issues.

 - The series "x86/module: use large ROX pages for text allocations"
   from Mike Rapoport teaches x86 to use large pages for
   read-only-execute module text.

 - The series "page allocation tag compression" from Suren Baghdasaryan
   is followon maintenance work for the new page allocation profiling
   feature.

 - The series "page-&gt;index removals in mm" from Matthew Wilcox remove
   most references to page-&gt;index in mm/. A slow march towards shrinking
   struct page.

 - The series "damon/{self,kunit}tests: minor fixups for DAMON debugfs
   interface tests" from Andrew Paniakin performs maintenance work for
   DAMON's self testing code.

 - The series "mm: zswap swap-out of large folios" from Kanchana Sridhar
   improves zswap's batching of compression and decompression. It is a
   step along the way towards using Intel IAA hardware acceleration for
   this zswap operation.

 - The series "kasan: migrate the last module test to kunit" from
   Sabyrzhan Tasbolatov completes the migration of the KASAN built-in
   tests over to the KUnit framework.

 - The series "implement lightweight guard pages" from Lorenzo Stoakes
   permits userapace to place fault-generating guard pages within a
   single VMA, rather than requiring that multiple VMAs be created for
   this. Improved efficiencies for userspace memory allocators are
   expected.

 - The series "memcg: tracepoint for flushing stats" from JP Kobryn uses
   tracepoints to provide increased visibility into memcg stats flushing
   activity.

 - The series "zram: IDLE flag handling fixes" from Sergey Senozhatsky
   fixes a zram buglet which potentially affected performance.

   from Kairui Song optimizes list_lru memory utilization when lockdep
   is enabled.
