sh: Remove CONFIG_VSYSCALL reference from UAPI
AT_SYSINFO_EHDR defines the auxvector index representing the vDSO
entrypoint. Its value or presence does not depend on whether a vDSO
is actually provided by the kernel.
The definition of AT_SYSINFO_EHDR was gated between CONFIG_VSYSCALL to
avoid a default gate VMA to be created. However that default gate VMA
was removed entirely in commit

Merge tag 'pci-v7.1-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/pci/pci
Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham
P)
- Enable AtomicOps only if we know the Root Port supports them (Gerd
Bayer)
- Don't enable AtomicOps for RCiEPs since none of them need Atomic
Ops and we can't tell whether the Root Complex would support them
(Gerd Bayer)
- Leave Precision Time Measurement disabled until a driver enables it
to avoid PCIe errors (Mika Westerberg)
- Make pci_set_vga_state() fail if bridge doesn't support VGA
routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return
errors to vga_get() callers including userspace via
/dev/vga_arbiter (Simon Richter)
- Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3,
rzg3s drivers (where the actual controller constraints are known),
and remove validation from the generic OF DT accessor (Hans Zhang)
- Remove pc110pad driver (no longer useful after 486 CPU support
removed) and no_pci_devices() (pc110pad was the last user) (Dmitry
Torokhov, Heiner Kallweit)
Resource management:
- Prevent assigning space to unimplemented bridge windows; previously
we mistakenly assumed prefetchable window existed and assigned
space and put a BAR there (Ahmed Naseef)
- Avoid shrinking bridge windows to fit in the initial Root Port
window; fixes one problem with devices with large BARs connected
via switches, e.g., Thunderbolt (Ilpo Järvinen)
- Pass full extent of empty space, not just the aligned space, to
resource_alignf callback so free space before the requested
alignment can be used (Ilpo Järvinen)
- Place small resources before larger ones for better utilization of
address space (Ilpo Järvinen)
- Fix alignment calculation for resource size larger than align,
e.g., bridge windows larger than the 1MB required alignment (Ilpo
Järvinen)
Reset:
- Update slot handling so all ARI functions are treated as being in
the same slot. They're all reset by Secondary Bus Reset, but
previously drivers of ARI functions that appeared to be on a
non-zero device weren't notified and fatal hardware errors could
result (Keith Busch)
- Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug
events (Keith Busch)
- Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked
by CXL because it has no effect (Vidya Sagar)
- Avoid FLR for AMD NPU device, where it causes the device to hang
(Lizhi Hou)
Error handling:
- Clear only error bits in PCIe Device Status to avoid accidentally
clearing Emergency Power Reduction Detected (Shuai Xue)
- Check for AER errors even in devices without drivers (Lukas Wunner)
- Initialize ratelimit info so DPC and EDR paths log AER error
information (Kuppuswamy Sathyanarayanan)
Power control:
- Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so
generic pwrctrl driver can control it (Neil Armstrong)
Hotplug:
- Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core
doesn't complain when setting brightness fails because the endpoint
is gone (Richard Cheng)
Peer-to-peer DMA:
- Allow wildcards in list of host bridges that support peer-to-peer
DMA between hierarchy domains and add all Google SoCs (Jacob
Moroni)
Endpoint framework:
- Advertise dynamic inbound mapping support in pci-epf-test and
update host pci_endpoint_test to skip doorbell testing if not
advertised by endpoint (Koichiro Den)
- Return 0, not remaining timeout, when MHI eDMA ops complete so
mhi_ep_ring_add_element() doesn't interpret non-zero as failure
(Daniel Hodges)
- Remove vntb and ntb duplicate resource teardown that leads to oops
when .allow_link() fails or .drop_link() is called (Koichiro Den)
- Disable vntb delayed work before clearing BAR mappings and
doorbells to avoid oops caused by doing the work after resources
have been torn down (Koichiro Den)
- Add a way to describe reserved subregions within BARs, e.g.,
platform-owned fixed register windows, and use it for the RK3588
BAR4 DMA ctrl window (Koichiro Den)
- Add BAR_DISABLED for BARs that will never be available to an EPF
driver, and change some BAR_RESERVED annotations to BAR_DISABLED
(Niklas Cassel)
- Add NTB .get_dma_dev() callback for cases where DMA API requires a
different device, e.g., vNTB devices (Koichiro Den)
- Add reserved region types for MSI-X Table and PBA so Endpoint
controllers can them as describe hardware-owned regions in a
BAR_RESERVED BAR (Manikanta Maddireddy)
- Make Tegra194/234 BAR0 programmable and remove 1MB size limit
(Manikanta Maddireddy)
- Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED
(Manikanta Maddireddy)
- Add Tegra194 and Tegra234 device table entries to pci_endpoint_test
(Manikanta Maddireddy)
- Skip the BAR subrange selftest if there are not enough inbound
window resources to run the test (Christian Bruel)
New native PCIe controller drivers:
- Add DT binding and driver for Andes QiLai SoC PCIe host controller
(Randolph Lin)
- Add DT binding and driver for ESWIN PCIe Root Complex (Senchuan
Zhang)
Baikal T-1 PCIe controller driver:
- Remove driver since it never quite became usable (Andy Shevchenko)
Cadence PCIe controller driver:
- Implement byte/word config reads with dword (32-bit) reads because
some Cadence controllers don't support sub-dword accesses (Aksh
Garg)
CIX Sky1 PCIe controller driver:
- Add 'power-domains' to DT binding for SCMI power domain (Gary Yang)
Freescale i.MX6 PCIe controller driver:
- Add i.MX94 and i.MX943 to fsl,imx6q-pcie-ep DT binding (Richard
Zhu)
- Delay instead of polling for L2/L3 Ready after PME_Turn_off when
suspending i.MX6SX because LTSSM registers are inaccessible
(Richard Zhu)
- Separate PERST# assertion (for resetting endpoints) from core reset
(for resetting the RC itself) to prepare for new DTs with PERST#
GPIO in per-Root Port nodes (Sherry Sun)
- Retain Root Port MSI capability on i.MX7D, i.MX8MM, and i.MX8MQ so
MSI from downstream devices will work (Richard Zhu)
- Fix i.MX95 reference clock source selection when internal refclk is
used (Franz Schnyder)
Freescale Layerscape PCIe controller driver:
- Allow building as a removable module (Sascha Hauer)
MediaTek PCIe Gen3 controller driver:
- Use dev_err_probe() to simplify error paths and make deferred probe
messages visible in /sys/kernel/debug/devices_deferred (Chen-Yu
Tsai)
- Power off device if setup fails (Chen-Yu Tsai)
- Integrate new pwrctrl API to enable power control for WiFi/BT
adapters on mainboard or in PCIe or M.2 slots (Chen-Yu Tsai)
NVIDIA Tegra194 PCIe controller driver:
- Poll less aggressively and non-atomically for PME_TO_Ack during
transition to L2 (Vidya Sagar)
- Disable LTSSM after transition to Detect on surprise link down to
stop toggling between Polling and Detect (Manikanta Maddireddy)
- Don't force the device into the D0 state before L2 when suspending
or shutting down the controller (Vidya Sagar)
- Disable PERST# IRQ only in Endpoint mode because it's not
registered in Root Port mode (Manikanta Maddireddy)
- Handle 'nvidia,refclk-select' as optional (Vidya Sagar)
- Disable direct speed change in Endpoint mode so link speed change
is controlled by the host (Vidya Sagar)
- Set LTR values before link up to avoid bogus LTR messages with 0
latency (Vidya Sagar)
- Allow system suspend when the Endpoint link is down (Vidya Sagar)
- Use DWC IP core version, not Tegra custom values, to avoid DWC core
version check warnings (Manikanta Maddireddy)
- Apply ECRC workaround to devices based on DesignWare 5.00a as well
as 4.90a (Manikanta Maddireddy)
- Disable PM Substate L1.2 in Endpoint mode to work around Tegra234
erratum (Vidya Sagar)
- Delay post-PERST# cleanup until core is powered on to avoid CBB
timeout (Manikanta Maddireddy)
- Assert CLKREQ# so switches that forward it to their downstream side
can bring up those links successfully (Vidya Sagar)
- Calibrate pipe to UPHY for Endpoint mode to reset stale PLL state
from any previous bad link state (Vidya Sagar)
- Remove IRQF_ONESHOT flag from Endpoint interrupt registration so
DMA driver and Endpoint controller driver can share the interrupt
line (Vidya Sagar)
- Enable DMA interrupt to support DMA in both Root Port and Endpoint
modes (Vidya Sagar)
- Enable hardware link retraining after link goes down in Endpoint
mode (Vidya Sagar)
- Add DT binding and driver support for core clock monitoring (Vidya
Sagar)
Qualcomm PCIe controller driver:
- Advertise 'Hot-Plug Capable' and set 'No Command Completed Support'
since Qcom Root Ports support hotplug events like DL_Up/Down and
can accept writes to Slot Control without delays between writes
(Krishna Chaitanya Chundru)
Renesas R-Car PCIe controller driver:
- Mark Endpoint BAR0 and BAR2 as Resizable (Koichiro Den)
- Reduce EPC BAR alignment requirement to 4K (Koichiro Den)
Renesas RZ/G3S PCIe controller driver:
- Add RZ/G3E to DT binding and to driver (John Madieu)
- Assert (not deassert) resets in probe error path (John Madieu)
- Assert resets in suspend path in reverse order they were deasserted
during probe (John Madieu)
- Rework inbound window algorithm to prevent mapping more than
intended region and enforce alignment on size, to prepare for
RZ/G3E support (John Madieu)
Rockchip DesignWare PCIe controller driver:
- Add tracepoints for PCIe controller LTSSM transitions and link rate
changes (Shawn Lin)
- Trace LTSSM events collected by the dw-rockchip debug FIFO (Shawn
Lin)
SOPHGO PCIe controller driver:
- Disable ASPM L0s and L1 on Sophgo 2042 PCIe Root Ports that
advertise support for them (Yao Zi)
Synopsys DesignWare PCIe controller driver:
- Continue with system suspend even if an Endpoint doesn't respond
with PME_TO_Ack message (Manivannan Sadhasivam)
- Set Endpoint MSI-X Table Size in the correct function of a
multi-function device when configuring MSI-X, not in Function 0
(Aksh Garg)
- Set Max Link Width and Max Link Speed for all functions of a
multi-function device, not just Function 0 (Aksh Garg)
- Expose PCIe event counters in groups 5-7 in debugfs (Hans Zhang)
Miscellaneous:

crypto: Remove michael_mic from crypto_shash API
Remove the "michael_mic" crypto_shash algorithm, since it's no longer used. Its only users were wireless drivers, which have now been converted to use the michael_mic() function instead. It makes sense that no other users ever appeared: Michael MIC is an insecure algorithm that is specific to WPA TKIP, which itself was an interim security solution to replace the broken WEP standard.

arch, mm: consolidate empty_zero_page
Reduce 22 declarations of empty_zero_page to 3 and 23 declarations of ZERO_PAGE() to 4. Every architecture defines empty_zero_page that way or another, but for the most of them it is always a page aligned page in BSS and most definitions of ZERO_PAGE do virt_to_page(empty_zero_page). Move Linus vetted x86 definition of empty_zero_page and ZERO_PAGE() to the core MM and drop these definitions in architectures that do not implement colored zero page (MIPS and s390). ZERO_PAGE() remains a macro because turning it to a wrapper for a static inline causes severe pain in header dependencies. For the most part the change is mechanical, with these being noteworthy: * alpha: aliased empty_zero_page with ZERO_PGE that was also used for boot parameters. Switching to a generic empty_zero_page removes the aliasing and keeps ZERO_PGE for boot parameters only * arm64: uses __pa_symbol() in ZERO_PAGE() so that definition of ZERO_PAGE() is kept intact. * m68k/parisc/um: allocated empty_zero_page from memblock, although they do not support zero page coloring and having it in BSS will work fine. * sparc64 can have empty_zero_page in BSS rather allocate it, but it can't use virt_to_page() for BSS. Keep it's definition of ZERO_PAGE() but instead of allocating it, make mem_map_zero point to empty_zero_page. * sh: used empty_zero_page for boot parameters at the very early boot. Rename the parameters page to boot_params_page and let sh use the generic empty_zero_page. * hexagon: had an amusing comment about empty_zero_page /* A handy thing to have if one has the RAM. Declared in head.S */ that unfortunately had to go :) Link: https://lkml.kernel.org/r/20260211103141.3215197-4-rppt@kernel.org Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org> Acked-by: Helge Deller <deller@gmx.de> [parisc] Tested-by: Helge Deller <deller@gmx.de> [parisc] Reviewed-by: Christophe Leroy (CS GROUP) <chleroy@kernel.org> Acked-by: Dave Hansen <dave.hansen@linux.intel.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: Magnus Lindholm <linmag7@gmail.com> [alpha] Acked-by: Dinh Nguyen <dinguyen@kernel.org> [nios2] Acked-by: Andreas Larsson <andreas@gaisler.com> [sparc] Acked-by: David Hildenbrand (Arm) <david@kernel.org> Acked-by: Liam R.

PCI: Align head space better
When a bridge window contains big and small resource(s), the small resource(s) may not amount to the half of the size of the big resource which would allow calculate_head_align() to shrink the head alignment. This results in always placing the small resource(s) after the big resource. In general, it would be good to be able to place the small resource(s) before the big resource to achieve better utilization of the address space. In the cases where the large resource can only fit at the end of the window, it is even required. However, carrying the information over from pbus_size_mem() and calculate_head_align() to __pci_assign_resource() and pcibios_align_resource() is not easy with the current data structures. A somewhat hacky way to move the non-aligning tail part to the head is possible within pcibios_align_resource(). The free space between the start of the free space span and the aligned start address can be compared with the non-aligning remainder of the size. If the free space is larger than the remainder, placing the remainder before the start address is possible. This relocation should generally work, because PCI resources consist only power-of-2 atoms. Various arch requirements may still need to override the relocation, so the relocation is only applied selectively in such cases.

resource: Pass full extent of empty space to resource_alignf callback
__find_resource_space() calculates the full extent of empty space but only passes the aligned space to resource_alignf callback.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org> |

arch, mm: consolidate initialization of SPARSE memory model
Every architecture calls sparse_init() during setup_arch() although the data structures created by sparse_init() are not used until the initialization of the core MM. Beside the code duplication, calling sparse_init() from architecture specific code causes ordering differences of vmemmap and HVO initialization on different architectures. Move the call to sparse_init() from architecture specific code to free_area_init() to ensure that vmemmap and HVO initialization order is always the same.

arch, mm: consolidate initialization of nodes, zones and memory map
To initialize node, zone and memory map data structures every architecture calls free_area_init() during setup_arch() and passes it an array of zone limits. Beside code duplication it creates "interesting" ordering cases between allocation and initialization of hugetlb and the memory map. Some architectures allocate hugetlb pages very early in setup_arch() in certain cases, some only create hugetlb CMA areas in setup_arch() and sometimes hugetlb allocations happen mm_core_init(). With arch_zone_limits_init() helper available now on all architectures it is no longer necessary to call free_area_init() from architecture setup code. Rather core MM initialization can call arch_zone_limits_init() in a single place. This allows to unify ordering of hugetlb vs memory map allocation and initialization. Remove the call to free_area_init() from architecture specific code and place it in a new mm_core_init_early() function that is called immediately after setup_arch(). After this refactoring it is possible to consolidate hugetlb allocations and eliminate differences in ordering of hugetlb and memory map initialization among different architectures. As the first step of this consolidation move hugetlb_bootmem_alloc() to mm_core_early_init().

sh: introduce arch_zone_limits_init()
Move calculations of zone limits to a dedicated arch_zone_limits_init() function. Later MM core will use this function as an architecture specific callback during nodes and zones initialization and thus there won't be a need to call free_area_init() from every architecture.

rseq: Implement sys_rseq_slice_yield()
Provide a new syscall which has the only purpose to yield the CPU after the kernel granted a time slice extension. sched_yield() is not suitable for that because it unconditionally schedules, but the end of the time slice extension is not required to schedule when the task was already preempted. This also allows to have a strict check for termination to catch user space invoking random syscalls including sched_yield() from a time slice extension region.

sound fixes for 6.19-rc1
The rest for 6.19 merge window. The only slightly large change is
the enablement of CIX HD-audio controller, which took a bit time to
be cooked up, while most of other changes are device-specific small
trivial fixes.
- Default disablement of the kconfig for decades old pre-release
alsa-lib PCM API; it's only the default config value change, so
it can't lead to any regressions for the existing setups
- Support for CIX HD-audio controller
- A few ASoC ACP fixes
- Fixes for ASoC cirrus, bcm, wcd, qcom, ak platforms
- Trivial hardening for FireWire and USB-audio
- HD-audio Intel binding fix and quirks

Core kernel bug handling infrastructure changes for v6.19:
- Improve WARN(), which has vararg printf like arguments,
to work with the x86 #UD based WARN-optimizing infrastructure
by hiding the format in the bug_table and replacing this
first argument with the address of the bug-table entry,
while making the actual function that's called a UD1 instruction.
(Peter Zijlstra)
- Introduce the CONFIG_DEBUG_BUGVERBOSE_DETAILED Kconfig switch
(Ingo Molnar, s390 support by Heiko Carstens)
Fixes and cleanups:
- bugs/s390: Remove private WARN_ON() implementation (Heiko Carstens)
- <asm/bugs.h>: Make i386 use GENERIC_BUG_RELATIVE_POINTERS

crypto: ansi_cprng - Remove unused ansi_cprng algorithm
Remove ansi_cprng, since it's obsolete and unused, as confirmed at https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/ This was originally added in 2008, apparently as a FIPS approved random number generator. Whether this has ever belonged upstream is questionable. Either way, ansi_cprng is no longer usable for this purpose, since it's been superseded by the more modern algorithms in crypto/drbg.c, and FIPS itself no longer allows it. (NIST SP 800-131A Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after 2015. NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.) Therefore, there is no reason to keep it around.

syscore: Pass context data to callbacks
Several drivers can benefit from registering per-instance data along with the syscore operations. To achieve this, move the modifiable fields out of the syscore_ops structure and into a separate struct syscore that can be registered with the framework.

66f8e4df00 |
Ext4 bug fixes for 6.18-rc2, including
* Fix regression caused by removing CONFIG_EXT3_FS when testing some
very old defconfigs
* Avoid a BUG_ON when opening a file on a maliciously corrupted file system
* Avoid mm warnings when freeing a very large orphan file metadata
* Avoid a theoretical races between metadata wrtteback and checkpoints.
(It's very hard to hit in practice, since the race requires that the
writeback take a very long time.)

It's a long story - the [1/N] changelog spells out the considerations. - The 11 patch series "Add and use memdesc_flags_t" from Matthew Wilcox gets us started on the memdesc project. Please see https://kernelnewbies.org/MatthewWilcox/Memdescs and https://blogs.oracle.com/linux/post/introducing-memdesc. - The 3 patch series "Tiny optimization for large read operations" from Chi Zhiling improves the efficiency of the pagecache read path. - The 5 patch series "Better split_huge_page_test result check" from Zi Yan improves our folio splitting selftest code. - The 2 patch series "test that rmap behaves as expected" from Wei Yang adds some rmap selftests. - The 3 patch series "remove write_cache_pages()" from Christoph Hellwig removes that function and converts its two remaining callers. - The 2 patch series "selftests/mm: uffd-stress fixes" from Dev Jain fixes some UFFD selftests issues. - The 3 patch series "introduce kernel file mapped folios" from Boris Burkov introduces the concept of "kernel file pages".

It is felt that a read-only mode KASAN is suitable for use in production systems rather than debug-only. - The 3 patch series "mm: hugetlb: cleanup hugetlb folio allocation" from Kefeng Wang does some tidying in the hugetlb folio allocation code. - The 12 patch series "mm: establish const-correctness for pointer parameters" from Max Kellermann makes quite a number of the MM API functions more accurate about the constness of their arguments. This was getting in the way of subsystems (in this case CEPH) when they attempt to improving their own const/non-const accuracy. - The 7 patch series "Cleanup free_pages() misuse" from Vishal Moola fixes a number of code sites which were confused over when to use free_pages() vs __free_pages(). - The 3 patch series "Add Rust abstraction for Maple Trees" from Alice Ryhl makes the mapletree code accessible to Rust. Required by nouveau and by its forthcoming successor: the new Rust Nova driver. - The 2 patch series "selftests/mm: split_huge_page_test: split_pte_mapped_thp improvements" from David Hildenbrand adds a fix and some cleanups to the thp selftesting code. - The 14 patch series "mm, swap: introduce swap table as swap cache (phase I)" from Chris Li and Kairui Song is the first step along the path to implementing "swap tables" - a new approach to swap allocation and state tracking which is expected to yield speed and space improvements.

It also increases the success rate of MADV_COLLAPSE against an anon vma. - The 2 patch series "mm: do not assume file == vma->vm_file in compat_vma_mmap_prepare()" from Lorenzo Stoakes moves us further towards removal of file_operations.mmap(). This patchset concentrates upon clearing up the treatment of stacked filesystems. - The 6 patch series "mm: Improve mlock tracking for large folios" from Kiryl Shutsemau provides some fixes and improvements to mlock's tracking of large folios. /proc/meminfo's "Mlocked" field became more accurate. - The 2 patch series "mm/ksm: Fix incorrect accounting of KSM counters during fork" from Donet Tom fixes several user-visible KSM stats inaccuracies across forks and adds selftest code to verify these counters. - The 2 patch series "mm_slot: fix the usage of mm_slot_entry" from Wei Yang addresses some potential but presently benign issues in KSM's mm_slot handling. -----BEGIN PGP SIGNATURE----- iHUEABYKAB0WIQTTMBEPP41GrTpTJgfdBJ7gKXxAjgUCaN3cywAKCRDdBJ7gKXxA jtaPAQDmIuIu7+XnVUK5V11hsQ/5QtsUeLHV3OsAn4yW5/3dEQD/UddRU08ePN+1 2VRB0EwkLAdfMWW7TfiNZ+yhuoiL/AA= =4mhY -----END PGP SIGNATURE----- Merge tag 'mm-stable-2025-10-01-19-00' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - "mm, swap: improve cluster scan strategy" from Kairui Song improves performance and reduces the failure rate of swap cluster allocation - "support large align and nid in Rust allocators" from Vitaly Wool permits Rust allocators to set NUMA node and large alignment when perforning slub and vmalloc reallocs - "mm/damon/vaddr: support stat-purpose DAMOS" from Yueyang Pan extend DAMOS_STAT's handling of the DAMON operations sets for virtual address spaces for ops-level DAMOS filters - "execute PROCMAP_QUERY ioctl under per-vma lock" from Suren Baghdasaryan reduces mmap_lock contention during reads of /proc/pid/maps - "mm/mincore: minor clean up for swap cache checking" from Kairui Song performs some cleanup in the swap code - "mm: vm_normal_page*() improvements" from David Hildenbrand provides code cleanup in the pagemap code - "add persistent huge zero folio support" from Pankaj Raghav provides a block layer speedup by optionalls making the huge_zero_pagepersistent, instead of releasing it when its refcount falls to zero - "kho: fixes and cleanups" from Mike Rapoport adds a few touchups to the recently added Kexec Handover feature - "mm: make mm->flags a bitmap and 64-bit on all arches" from Lorenzo Stoakes turns mm_struct.flags into a bitmap.

arch: Add the macro COMPILE_OFFSETS to all the asm-offsets.c
The include/generated/asm-offsets.h is generated in Kbuild during compiling from arch/SRCARCH/kernel/asm-offsets.c. When we want to generate another similar offset header file, circular dependency can happen. For example, we want to generate a offset file include/generated/test.h, which is included in include/sched/sched.h. If we generate asm-offsets.h first, it will fail, as include/sched/sched.h is included in asm-offsets.c and include/generated/test.h doesn't exist; If we generate test.h first, it can't success neither, as include/generated/asm-offsets.h is included by it. In x86_64, the macro COMPILE_OFFSETS is used to avoid such circular dependency. We can generate asm-offsets.h first, and if the COMPILE_OFFSETS is defined, we don't include the "generated/test.h". And we define the macro COMPILE_OFFSETS for all the asm-offsets.c for this purpose.

mm: introduce memdesc_flags_t
Patch series "Add and use memdesc_flags_t". At some point struct page will be separated from struct slab and struct folio. This is a step towards that by introducing a type for the 'flags' word of all three structures. This gives us a certain amount of type safety by establishing that some of these unsigned longs are different from other unsigned longs in that they contain things like node ID, section number and zone number in the upper bits. That lets us have functions that can be easily called by anyone who has a slab, folio or page (but not easily by anyone else) to get the node or zone. There's going to be some unusual merge problems with this as some odd bits of the kernel decide they want to print out the flags value or something similar by writing page->flags and now they'll need to write page->flags.f instead. That's most of the churn here. Maybe we should be removing these things from the debug output? This patch (of 11): Wrap the unsigned long flags in a typedef. In upcoming patches, this will provide a strong hint that you can't just pass a random unsigned long to functions which take this as an argument.

sh: Add __attribute_const__ to ffs()-family implementations
While tracking down a problem where constant expressions used by BUILD_BUG_ON() suddenly stopped working[1], we found that an added static initializer was convincing the compiler that it couldn't track the state of the prior statically initialized value. Tracing this down found that ffs() was used in the initializer macro, but since it wasn't marked with __attribute__const__, the compiler had to assume the function might change variable states as a side-effect (which is not true for ffs(), which provides deterministic math results). Add missing __attribute_const__ annotations to SH's implementations of __ffs() and ffz() functions. These are pure mathematical functions that always return the same result for the same input with no side effects, making them eligible for compiler optimization. Build tested ARCH=sh defconfig with GCC sh4-linux-gnu 14.2.0.

Significant patch series in this pull request:
- The 2 patch series "squashfs: Remove page->mapping references" from
Matthew Wilcox gets us closer to being able to remove page->mapping.
- The 5 patch series "relayfs: misc changes" from Jason Xing does some
maintenance and minor feature addition work in relayfs.
- The 5 patch series "kdump: crashkernel reservation from CMA" from Jiri
Bohac switches us from static preallocation of the kdump crashkernel's
working memory over to dynamic allocation. So the difficulty of
a-priori estimation of the second kernel's needs is removed and the
first kernel obtains extra memory.
- The 5 patch series "generalize panic_print's dump function to be used
by other kernel parts" from Feng Tang implements some consolidation and
rationalizatio of the various ways in which a faiing kernel splats
information at the operator.

Networking changes for 6.17.
Core & protocols
----------------
- Wrap datapath globals into net_aligned_data, to avoid false sharing.
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
- Add SO_INQ and SCM_INQ support to AF_UNIX.
- Add SIOCINQ support to AF_VSOCK.
- Add TCP_MAXSEG sockopt to MPTCP.
- Add IPv6 force_forwarding sysctl to enable forwarding per interface.
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB.
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users.
- Convert TCP send queue handling from tasklet to BH workque.
- Improve BPF iteration over TCP sockets to see each socket exactly once.
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel NAPI
thread when threaded NAPI gets disabled. Previously thread would stick
around until ifdown due to tricky synchronization.
- Allow multicast routing to take effect on locally-generated packets.
- Add output interface argument for End.X in segment routing.
- MCTP: add support for gateway routing, improve bind() handling.
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed.
- Support NUD_PERMANENT for proxy neighbor entries.
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
- Add sequence numbers to netconsole messages. Unregister netconsole's
console when all net targets are removed. Code refactoring.
Add a number of selftests.
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup.
- Support inspecting ref_tracker state via DebugFS.
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links.
- Allow providing upcall pid for the 'execute' command in openvswitch.
- Remove DCCP support from Netfilter's conntrack.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.
Driver API
----------
- Support RSS and hashing configuration over ethtool Netlink.
- Add dedicated ethtool callbacks for getting and setting hashing fields.
- Add support for power budget evaluation strategy in PSE /
Power-over-Ethernet. Generate Netlink events for overcurrent etc.
- Support DPLL phase offset monitoring across all device inputs.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Wrap datapath globals into net_aligned_data, to avoid false sharing
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container)
- Add SO_INQ and SCM_INQ support to AF_UNIX
- Add SIOCINQ support to AF_VSOCK
- Add TCP_MAXSEG sockopt to MPTCP
- Add IPv6 force_forwarding sysctl to enable forwarding per interface
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users
- Convert TCP send queue handling from tasklet to BH workque
- Improve BPF iteration over TCP sockets to see each socket exactly
once
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel
NAPI thread when threaded NAPI gets disabled. Previously thread
would stick around until ifdown due to tricky synchronization
- Allow multicast routing to take effect on locally-generated packets
- Add output interface argument for End.X in segment routing
- MCTP: add support for gateway routing, improve bind() handling
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed
- Support NUD_PERMANENT for proxy neighbor entries
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM
- Add sequence numbers to netconsole messages. Unregister
netconsole's console when all net targets are removed. Code
refactoring. Add a number of selftests
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup
- Support inspecting ref_tracker state via DebugFS
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links
- Allow providing upcall pid for the 'execute' command in openvswitch
- Remove DCCP support from Netfilter's conntrack
- Disallow multiple packet duplications in the queuing layer
- Prevent use of deprecated iptables code on PREEMPT_RT
Driver API:
- Support RSS and hashing configuration over ethtool Netlink
- Add dedicated ethtool callbacks for getting and setting hashing
fields
- Add support for power budget evaluation strategy in PSE /
Power-over-Ethernet. Generate Netlink events for overcurrent etc
- Support DPLL phase offset monitoring across all device inputs.
Support providing clock reference and SYNC over separate DPLL
inputs
- Support traffic classes in devlink rate API for bandwidth
management
- Remove rtnl_lock dependency from UDP tunnel port configuration
