bd0a905c22 arch: Add the macro COMPILE_OFFSETS to all the asm-offsets.c
[ Upstream commit 35561bab76 ]

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.

e9d7803681 ARM: AM33xx: Implement TI advisory 1.0.36 (EMU0/EMU1 pins state on reset)
commit 8a6506e1ba upstream.

There is an issue possible where TI AM33xx SoCs do not boot properly after
a reset if EMU0/EMU1 pins were used as GPIO and have been driving low level
actively prior to reset [1].

"Advisory 1.0.36 EMU0 and EMU1: Terminals Must be Pulled High Before
ICEPick Samples

The state of the EMU[1:0] terminals are latched during reset to determine
ICEPick boot mode. For normal device operation, these terminals must be
pulled up to a valid high logic level ( > VIH min) before ICEPick samples
the state of these terminals, which occurs
[five CLK_M_OSC clock cycles - 10 ns] after the falling edge of WARMRSTn.

Many applications may not require the secondary GPIO function of the
EMU[1:0] terminals. In this case, they would only be connected to pull-up
resistors, which ensures they are always high when ICEPick samples.
However, some applications may need to use these terminals as GPIO where
they could be driven low before reset is asserted. This usage of the
EMU[1:0] terminals may require special attention to ensure the terminals
are allowed to return to a valid high-logic level before ICEPick samples
the state of these terminals.

When any device reset is asserted, the pin mux mode of EMU[1:0] terminals
configured to operate as GPIO (mode 7) will change back to EMU input
(mode 0) on the falling edge of WARMRSTn. This only provides a short period
of time for the terminals to return high if driven low before reset is
asserted...

If the EMU[1:0] terminals are configured to operate as GPIO, the product
should be designed such these terminals can be pulled to a valid high-logic
level within 190 ns after the falling edge of WARMRSTn."

We've noticed this problem with custom am335x hardware in combination with
recently implemented cold reset method
(commit 6521f6a195 ("ARM: AM33xx: PRM: Implement REBOOT_COLD")).
It looks like the problem can affect other HW, for instance AM335x
Chiliboard, because the latter has LEDs on GPIO3_7/GPIO3_8 as well.

One option would be to check if the pins are in GPIO mode and either switch
to output active high, or switch to input and poll until the external
pull-ups have brought the pins to the desired high state. But fighting
with GPIO driver for these pins is probably not the most straight forward
approch in a reboot handler.

Fortunately we can easily control pinmuxing here and rely on the external
pull-ups. TI recommends 4k7 external pull up resistors [2] and even with
quite conservative estimation for pin capacity (1 uF should never happen)
the required delay shall not exceed 5ms.

07d8d3b1ad ARM: dts: omap: am335x-cm-t335: Remove unused mcasp num-serializer property
[ Upstream commit 27322753c8 ]

The dtbs_check validation for am335x-cm-t335.dtb flags an error
for an unevaluated 'num-serializer' property in the mcasp0 node.

This property is obsolete; it is not defined in the davinci-mcasp-audio
schema and is not used by the corresponding (or any) driver.

Remove this unused property to fix the schema validation warning.

e0d6fb7923 arch: copy_thread: pass clone_flags as u64
[ Upstream commit bbc46b23af ]

With the introduction of clone3 in commit 7f192e3cd3 ("fork: add
clone3") the effective bit width of clone_flags on all architectures was
increased from 32-bit to 64-bit, with a new type of u64 for the flags.
However, for most consumers of clone_flags the interface was not
changed from the previous type of unsigned long.

While this works fine as long as none of the new 64-bit flag bits
(CLONE_CLEAR_SIGHAND and CLONE_INTO_CGROUP) are evaluated, this is still
undesirable in terms of the principle of least surprise.

Thus, this commit fixes all relevant interfaces of the copy_thread
function that is called from copy_process to consistently pass
clone_flags as u64, so that no truncation to 32-bit integers occurs on
32-bit architectures.

The function module_arch_freeing_init() defined in arch/arm/kernel/module.c
is supposed to override a weak function of the same name defined in
kernel/module/main.c. However, the ARM override is also marked as weak,
which means that selecting the correct function unnecessarily depends on
the order in which object files with both functions are passed to the

linker. Although it happens to be correct at the moment, the proper pattern
is to make the ARM override a strong definition.

29341c6c18 ARM: dts: kirkwood: Fix sound DAI cells for OpenRD clients
A previous commit changed the '#sound-dai-cells' property for the
kirkwood audio controller from 1 to 0 in the kirkwood.dtsi file,
but did not update the corresponding 'sound-dai' property in the
kirkwood-openrd-client.dts file.

This created a mismatch, causing a dtbs_check validation error where
the dts provides one cell (<&audio0 0>) while the .dtsi expects zero.

Remove the extraneous cell from the 'sound-dai' property to fix the
schema validation warning and align with the updated binding.

On SoCFPGA/Sodia board, mdio bus cannot be probed, so the PHY cannot be

```

```

To probe the mdio bus, add "snps,dwmac-mdio" as compatible string of the
mdio bus. Also the PHY address connected to this board is 4. Therefore,
change to 4.

b9a10f8764 soc: fixes for 6.17, part 2
These are mainly devicetree fixes for the rockchip and nxp platforms on
 arm64, addressing mistakes in the board and soc specific descriptions.
 In particular the newly added Rock 5T board required multiple bugfixes for
 PCIe and USB, while on the i.MX platform there are a number of regulator
 related fixes. The only other platforms with devicetree fixes are at91
 with a fixup for SD/MMC and a change to enable all the available UARTS
 on the Axiado reference board.
 
 Also on the at91 platform, a Kconfig change addresses a regression that
 stopped the DMA engine from working in 6.17-rc.
 
 Three drivers each have a simple bugfix, stopping incorrect behavior in
 op-tee firmware, the tee subsystem and the qualcomm mdt_loader.
 
 Two trivial MAINTAINERS file changes are needed to make sure that
 patches reach the correct maintainer, but don't change the actual
 responsibilities.

85f5d8e369 ARM: dts: armada-370-db: Fix stereo audio input routing on Armada 370
The simple-audio-card configuration for the Armada 370 development
board incorrectly routed the left channel signal ("AIN1L") to both
sides of the stereo "In Jack".

This commit corrects the typo for the right channel, changing the
second "AIN1L" entry to "AIN1R" to enable proper stereo input
recording.

d9d87d90cc treewide: rename GPIO set callbacks back to their original names
The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

beace86e61 Summary of significant series in this pull request:
- The 4 patch series "mm: ksm: prevent KSM from breaking merging of new
   VMAs" from Lorenzo Stoakes addresses an issue with KSM's
   PR_SET_MEMORY_MERGE mode: newly mapped VMAs were not eligible for
   merging with existing adjacent VMAs.
 
 - The 4 patch series "mm/damon: introduce DAMON_STAT for simple and
   practical access monitoring" from SeongJae Park adds a new kernel module
   which simplifies the setup and usage of DAMON in production
   environments.
 
 - The 6 patch series "stop passing a writeback_control to swap/shmem
   writeout" from Christoph Hellwig is a cleanup to the writeback code
   which removes a couple of pointers from struct writeback_control.
 
 - The 7 patch series "drivers/base/node.c: optimization and cleanups"
   from Donet Tom contains largely uncorrelated cleanups to the NUMA node
   setup and management code.
 
 - The 4 patch series "mm: userfaultfd: assorted fixes and cleanups" from
   Tal Zussman does some maintenance work on the userfaultfd code.
 
 - The 5 patch series "Readahead tweaks for larger folios" from Ryan
   Roberts implements some tuneups for pagecache readahead when it is
   reading into order>0 folios.
 
 - The 4 patch series "selftests/mm: Tweaks to the cow test" from Mark
   Brown provides some cleanups and consistency improvements to the
   selftests code.
 
 - The 4 patch series "Optimize mremap() for large folios" from Dev Jain
   does that.  A 37% reduction in execution time was measured in a
   memset+mremap+munmap microbenchmark.
 
 - The 5 patch series "Remove zero_user()" from Matthew Wilcox expunges
   zero_user() in favor of the more modern memzero_page().
 
 - The 3 patch series "mm/huge_memory: vmf_insert_folio_*() and
   vmf_insert_pfn_pud() fixes" from David Hildenbrand addresses some warts
   which David noticed in the huge page code.  These were not known to be
   causing any issues at this time.
 
 - The 3 patch series "mm/damon: use alloc_migrate_target() for
   DAMOS_MIGRATE_{HOT,COLD" from SeongJae Park provides some cleanup and
   consolidation work in DAMON.
 
 - The 3 patch series "use vm_flags_t consistently" from Lorenzo Stoakes
   uses vm_flags_t in places where we were inappropriately using other
   types.
 
 - The 3 patch series "mm/memfd: Reserve hugetlb folios before
   allocation" from Vivek Kasireddy increases the reliability of large page
   allocation in the memfd code.
 
 - The 14 patch series "mm: Remove pXX_devmap page table bit and pfn_t
   type" from Alistair Popple removes several now-unneeded PFN_* flags.
 
 - The 5 patch series "mm/damon: decouple sysfs from core" from SeongJae
   Park implememnts some cleanup and maintainability work in the DAMON
   sysfs layer.
 
 - The 5 patch series "madvise cleanup" from Lorenzo Stoakes does quite a
   lot of cleanup/maintenance work in the madvise() code.
 
 - The 4 patch series "madvise anon_name cleanups" from Vlastimil Babka
   provides additional cleanups on top or Lorenzo's effort.
 
 - The 11 patch series "Implement numa node notifier" from Oscar Salvador
   creates a standalone notifier for NUMA node memory state changes.
   Previously these were lumped under the more general memory on/offline
   notifier.
 
 - The 6 patch series "Make MIGRATE_ISOLATE a standalone bit" from Zi Yan
   cleans up the pageblock isolation code and fixes a potential issue which
   doesn't seem to cause any problems in practice.
 
 - The 5 patch series "selftests/damon: add python and drgn based DAMON
   sysfs functionality tests" from SeongJae Park adds additional drgn- and
   python-based DAMON selftests which are more comprehensive than the
   existing selftest suite.
 
 - The 5 patch series "Misc rework on hugetlb faulting path" from Oscar
   Salvador fixes a rather obscure deadlock in the hugetlb fault code and
   follows that fix with a series of cleanups.
 
 - The 3 patch series "cma: factor out allocation logic from
   __cma_declare_contiguous_nid" from Mike Rapoport rationalizes and cleans
   up the highmem-specific code in the CMA allocator.
 
 - The 28 patch series "mm/migration: rework movable_ops page migration
   (part 1)" from David Hildenbrand provides cleanups and
   future-preparedness to the migration code.
 
 - The 2 patch series "mm/damon: add trace events for auto-tuned
   monitoring intervals and DAMOS quota" from SeongJae Park adds some
   tracepoints to some DAMON auto-tuning code.
 
 - The 6 patch series "mm/damon: fix misc bugs in DAMON modules" from
   SeongJae Park does that.
 
 - The 6 patch series "mm/damon: misc cleanups" from SeongJae Park also
   does what it claims.
 
 - The 4 patch series "mm: folio_pte_batch() improvements" from David
   Hildenbrand cleans up the large folio PTE batching code.
 
 - The 13 patch series "mm/damon/vaddr: Allow interleaving in
   migrate_{hot,cold} actions" from SeongJae Park facilitates dynamic
   alteration of DAMON's inter-node allocation policy.
 
 - The 3 patch series "Remove unmap_and_put_page()" from Vishal Moola
   provides a couple of page->folio conversions.
 
 - The 4 patch series "mm: per-node proactive reclaim" from Davidlohr
   Bueso implements a per-node control of proactive reclaim - beyond the
   current memcg-based implementation.
 
 - The 14 patch series "mm/damon: remove damon_callback" from SeongJae
   Park replaces the damon_callback interface with a more general and
   powerful damon_call()+damos_walk() interface.
 
 - The 10 patch series "mm/mremap: permit mremap() move of multiple VMAs"
   from Lorenzo Stoakes implements a number of mremap cleanups (of course)
   in preparation for adding new mremap() functionality: newly permit the
   remapping of multiple VMAs when the user is specifying MREMAP_FIXED.  It
   still excludes some specialized situations where this cannot be
   performed reliably.
 
 - The 3 patch series "drop hugetlb_free_pgd_range()" from Anthony Yznaga
   switches some sparc hugetlb code over to the generic version and removes
   the thus-unneeded hugetlb_free_pgd_range().
 
 - The 4 patch series "mm/damon/sysfs: support periodic and automated
   stats update" from SeongJae Park augments the present
   userspace-requested update of DAMON sysfs monitoring files.  Automatic
   update is now provided, along with a tunable to control the update
   interval.
 
 - The 4 patch series "Some randome fixes and cleanups to swapfile" from
   Kemeng Shi does what is claims.
 
 - The 4 patch series "mm: introduce snapshot_page" from Luiz Capitulino

   without tripping over the races inherent in operating on the live
   pageframe directly.
 
 - The 6 patch series "use per-vma locks for /proc/pid/maps reads" from
   Suren Baghdasaryan addresses the large contention issues which can be
   triggered by reads from that procfs file.  Latencies are reduced by more
   than half in some situations.  The series also introduces several new
   selftests for the /proc/pid/maps interface.
 
 - The 6 patch series "__folio_split() clean up" from Zi Yan cleans up
   __folio_split()!
 
 - The 7 patch series "Optimize mprotect() for large folios" from Dev

   cleanup work in the selftests code.
 
 - The 3 patch series "tools/testing: expand mremap testing" from Lorenzo
   Stoakes extends the mremap() selftest in several ways, including adding
   more checking of Lorenzo's recently added "permit mremap() move of
   multiple VMAs" feature.

Merge tag 'mm-stable-2025-07-30-15-25' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Pull MM updates from Andrew Morton:
 "As usual, many cleanups. The below blurbiage describes 42 patchsets.
  21 of those are partially or fully cleanup work. "cleans up",
  "cleanup", "maintainability", "rationalizes", etc.

  I never knew the MM code was so dirty.

  "mm: ksm: prevent KSM from breaking merging of new VMAs" (Lorenzo Stoakes)
     addresses an issue with KSM's PR_SET_MEMORY_MERGE mode: newly
     mapped VMAs were not eligible for merging with existing adjacent
     VMAs.

  "mm/damon: introduce DAMON_STAT for simple and practical access monitoring" (SeongJae Park)
     adds a new kernel module which simplifies the setup and usage of
     DAMON in production environments.

  "stop passing a writeback_control to swap/shmem writeout" (Christoph Hellwig)
     is a cleanup to the writeback code which removes a couple of
     pointers from struct writeback_control.

  "drivers/base/node.c: optimization and cleanups" (Donet Tom)
     contains largely uncorrelated cleanups to the NUMA node setup and
     management code.

  "mm: userfaultfd: assorted fixes and cleanups" (Tal Zussman)
     does some maintenance work on the userfaultfd code.

  "Readahead tweaks for larger folios" (Ryan Roberts)
     implements some tuneups for pagecache readahead when it is reading
     into order>0 folios.

  "selftests/mm: Tweaks to the cow test" (Mark Brown)
     provides some cleanups and consistency improvements to the
     selftests code.

  "Optimize mremap() for large folios" (Dev Jain)
     does that. A 37% reduction in execution time was measured in a
     memset+mremap+munmap microbenchmark.

  "Remove zero_user()" (Matthew Wilcox)
     expunges zero_user() in favor of the more modern memzero_page().

  "mm/huge_memory: vmf_insert_folio_*() and vmf_insert_pfn_pud() fixes" (David Hildenbrand)
     addresses some warts which David noticed in the huge page code.
     These were not known to be causing any issues at this time.

  "mm/damon: use alloc_migrate_target() for DAMOS_MIGRATE_{HOT,COLD" (SeongJae Park)
     provides some cleanup and consolidation work in DAMON.

  "use vm_flags_t consistently" (Lorenzo Stoakes)
     uses vm_flags_t in places where we were inappropriately using other
     types.

  "mm/memfd: Reserve hugetlb folios before allocation" (Vivek Kasireddy)
     increases the reliability of large page allocation in the memfd
     code.

  "mm: Remove pXX_devmap page table bit and pfn_t type" (Alistair Popple)
     removes several now-unneeded PFN_* flags.

  "mm/damon: decouple sysfs from core" (SeongJae Park)
     implememnts some cleanup and maintainability work in the DAMON
     sysfs layer.

  "madvise cleanup" (Lorenzo Stoakes)
     does quite a lot of cleanup/maintenance work in the madvise() code.

  "madvise anon_name cleanups" (Vlastimil Babka)
     provides additional cleanups on top or Lorenzo's effort.

  "Implement numa node notifier" (Oscar Salvador)
     creates a standalone notifier for NUMA node memory state changes.
     Previously these were lumped under the more general memory
     on/offline notifier.

  "Make MIGRATE_ISOLATE a standalone bit" (Zi Yan)
     cleans up the pageblock isolation code and fixes a potential issue
     which doesn't seem to cause any problems in practice.

  "selftests/damon: add python and drgn based DAMON sysfs functionality tests" (SeongJae Park)
     adds additional drgn- and python-based DAMON selftests which are
     more comprehensive than the existing selftest suite.

  "Misc rework on hugetlb faulting path" (Oscar Salvador)
     fixes a rather obscure deadlock in the hugetlb fault code and
     follows that fix with a series of cleanups.

  "cma: factor out allocation logic from __cma_declare_contiguous_nid" (Mike Rapoport)
     rationalizes and cleans up the highmem-specific code in the CMA
     allocator.

  "mm/migration: rework movable_ops page migration (part 1)" (David Hildenbrand)
     provides cleanups and future-preparedness to the migration code.

  "mm/damon: add trace events for auto-tuned monitoring intervals and DAMOS quota" (SeongJae Park)
     adds some tracepoints to some DAMON auto-tuning code.

  "mm/damon: fix misc bugs in DAMON modules" (SeongJae Park)
     does that.

  "mm/damon: misc cleanups" (SeongJae Park)
     also does what it claims.

  "mm: folio_pte_batch() improvements" (David Hildenbrand)
     cleans up the large folio PTE batching code.

  "mm/damon/vaddr: Allow interleaving in migrate_{hot,cold} actions" (SeongJae Park)
     facilitates dynamic alteration of DAMON's inter-node allocation
     policy.

  "Remove unmap_and_put_page()" (Vishal Moola)
     provides a couple of page->folio conversions.

  "mm: per-node proactive reclaim" (Davidlohr Bueso)
     implements a per-node control of proactive reclaim - beyond the
     current memcg-based implementation.

  "mm/damon: remove damon_callback" (SeongJae Park)
     replaces the damon_callback interface with a more general and
     powerful damon_call()+damos_walk() interface.

  "mm/mremap: permit mremap() move of multiple VMAs" (Lorenzo Stoakes)
     implements a number of mremap cleanups (of course) in preparation
     for adding new mremap() functionality: newly permit the remapping
     of multiple VMAs when the user is specifying MREMAP_FIXED. It still
     excludes some specialized situations where this cannot be performed
     reliably.

  "drop hugetlb_free_pgd_range()" (Anthony Yznaga)
     switches some sparc hugetlb code over to the generic version and
     removes the thus-unneeded hugetlb_free_pgd_range().

  "mm/damon/sysfs: support periodic and automated stats update" (SeongJae Park)
     augments the present userspace-requested update of DAMON sysfs
     monitoring files. Automatic update is now provided, along with a
     tunable to control the update interval.

  "Some randome fixes and cleanups to swapfile" (Kemeng Shi)
     does what is claims.

  "mm: introduce snapshot_page" (Luiz Capitulino and David Hildenbrand)
     provides (and uses) a means by which debug-style functions can grab
     a copy of a pageframe and inspect it locklessly without tripping
     over the races inherent in operating on the live pageframe
     directly.

     with large folios.

  "selftests/mm: reuse FORCE_READ to replace "asm volatile("" : "+r" (XXX));" and some cleanup" (wang lian)

90a871f74b ftrace changes for v6.17:
- Keep track of when fgraph_ops are registered or not
 
   Keep accounting of when fgraph_ops are registered as if a fgraph_ops is
   registered twice it can mess up the accounting and it will not work as
   expected later. Trigger a warning if something registers it twice as to
   catch bugs before they are found by things just not working as expected.
 
 - Make DYNAMIC_FTRACE always enabled for architectures that support it
 
   As static ftrace (where all functions are always traced) is very expensive
   and only exists to help architectures support ftrace, do not make it an
   option. As soon as an architecture supports DYNAMIC_FTRACE make it use it.
   This simplifies the code.
 
 - Remove redundant config HAVE_FTRACE_MCOUNT_RECORD
 
   The CONFIG_HAVE_FTRACE_MCOUNT was added to help simplify the
   DYNAMIC_FTRACE work, but now every architecture that implements
   DYNAMIC_FTRACE also has HAVE_FTRACE_MCOUNT set too, making it redundant
   with the HAVE_DYNAMIC_FTRACE.
 
 - Make pid_ptr string size match the comment
 
   In print_graph_proc() the pid_ptr string is of size 11, but the comment says
   /* sign + log10(MAX_INT) + '\0' */ which is actually 12.

8be4d31cb8 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.
    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.
 
 Device drivers
 --------------
 
  - Add a new Broadcom driver for 800G Ethernet (bnge).
 
  - Add a standalone driver for Microchip ZL3073x DPLL.
 
  - Remove IBM's NETIUCV device driver.
 
  - Ethernet high-speed NICs:

0919a5b3b1 soc: arm code changes for 6.17
Another small set of code changes for the 32-bit Arm platforms, and a
 trivial update to the Kconfig entry for the arm64 TI K3 chip.
 
 Andrew Davis cleans up the system reset handling, which touches a couple
 of platforms.
 
 The mediatek platform needs some code changes to support multiprocessing
 in the newly added support for the old mt6572 chip.

There are a few new variants of existing chips:
 
  - mt6572 is an older mobile phone chip from mediatek that was
    extremely popular a decade ago but never got upstreamed until now.
 
  - exynos2200 is a recent high-end mobile phone chip used in a
    few Samsung phones like the Galaxy S22
 
  - Renesas R-Car V4M-7 (R8A779H2) is an updated version of R-Car V4M
    (R8A779H0) and used in automotive applications
 
  - Tegra264 is a new chip from NVIDIA, but support is fairly minimal
    for now, and not much information is public about it.
 
 There are five more chips in a separate branch, as those are new
 chip families that I merged along with the necessary infrastructure.
 
 New board support is not that exciting, with a total of 33 newly
 added machines here:
 
  - Evaluation platforms for the chips above, plus TI am62d2 and
    Sophgo sg2042.
 
  - Six 32-bit industrial boards based on stm32, imx6 and am33 chips,
    plus eight 64-bit rockchips rk33xx/rk35xx, am62d2, t527, imx8 and
    imx95.
 
  - Two newly added ASPEED BMC based motherboards, and one that got
    removed
 
  - Phones and Tablets based on 32-bit mt6572, tegra30 and 64-bit
    msm8976 SoCs
 
  - Three Laptops based on Mediatek mt8186 and Qualcomm Snapdragon X1
 
  - A set-top box based on Amlogic meson-gxm.
 
 Updates for existing machines are spread over all the above families.
 One notable change here is support for the RP1 I/O chip used in
 Raspberry Pi 5.

fcb117e075 gpio updates for v6.17-rc1
GPIOLIB core:
 - introduce a parallel, limited sysfs user ABI that doesn't expose the
   global GPIO numbers to user-space while maintaining backward
   compatibility with the end goal of it completely replacing the existing
   interface, allowing us to remove it
 - remove the legacy devm_gpio_request() routine which has no more users
 - start the process of allowing to compile-out the legacy parts of the
   GPIO core for users who don't need it by introducing a new Kconfig
   option: GPIOLIB_LEGACY
 - don't use global GPIO numbers in debugfs output from the core code
   (drivers still do it, the work is ongoing)
 - start the process of moving the fields specific to the gpio-mmio helper
   out of the core struct gpio_chip into their own structure that wraps
   it: create a new header with modern interfaces and convert several
   drivers to using it
 - remove the platform data structure associated with the gpio-mmio helper
   from the kernel after having converted all remaining users to generic
   device properties
 - remove legacy struct gpio definition as it has no more users
 
 New drivers:
 - add the GPIO driver for the Apple System Management Controller
 
 Driver improvements:
 - add support for new models to gpio-adp5585, gpio-tps65219 and
   gpio-pca953x
 - extend the interrupt support in gpio-loongson-64bit
 - allow to mark the simulated GPIO lines as invalid in gpio-sim
 - convert all remaining GPIO drivers to using the new GPIO value setter
   callbacks
 - convert gpio-rcar to using simple device power management ops callbacks
 - don't check if current direction of a line is output before setting
   the value in gpio-pisosr and ti-fpc202: the GPIO core already handles
   that
 - also drop unneeded GPIO range checks in drivers, the core already makes
   sure we're within bounds when calling driver callbacks
 - use dev_fwnode() where applicable across GPIO drivers
 - set line value in gpio-zynqmp-modepin and gpio-twl6040 when the user
   wants to change direction of the pin to output even though these
   drivers don't need to do anything else to actually set the direction,
   otherwise a call like gpiod_direction_output(d, 1) will not result in
   the line driver high
 - remove the reduntant call to pm_runtime_mark_last_busy() from
   gpio-arizona
 - use lock guards in gpio-cadence and gpio-mxc
 - check the return values of regmap functions in gpio-wcd934x and
   gpio-tps65912
 - use better regmap interfaces in gpio-wcove and gpio-pca953x
 - remove dummy GPIO chip callbacks from several drivers in cases where
   the GPIO core can already handle their absence
 - allow building gpio-palmas as a module
 
 Fixes:
 - use correct bit widths (according to the documentation) in gpio-virtio
 
 Device-tree bindings:
 - convert several of the legacy .txt documents for many different devices
   to YAML, improving automatic validation
 - create a "trivial" GPIO DT schema that covers a wide range of simple
   hardware that share a set of basic GPIO properties
 - document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
 - document a new model for pca95xx
 - add and/or remove properties in YAML documents for gpio-rockchip,
   fsl,qoriq-gpio, arm,pl061 and gpio-xilinx
 
 Misc:
 - some minor refactoring in several places, adding/removing forward
   declarations, moving defines to better places, constify the arguments
   in some functions, remove duplicate includes, etc.
 - documentation updates

Merge tag 'gpio-updates-for-v6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "There's one new driver (Apple SMC) and extensions to existing drivers
  for supporting new HW models. A lot of different impovements across
  drivers and in core GPIO code. Details on that are in the signed tag
  as usual.

  We managed to remove some of the legacy APIs. Arnd Bergmann started to
  work on making the legacy bits optional so that we may compile them
  only for older platforms that still really need them.

  Rob Herring has done a lot of work to convert legacy .txt dt-bindings
  for GPIO controllers to YAML. There are only a few left now in the
  GPIO tree.

  A big part of the commits in this PR concern the conversion of GPIO
  drivers to using the new line value setter callbacks. This conversion
  is now complete treewide (unless I've missed something) and once all
  the changes from different trees land in mainline, I'll send you
  another PR containing a commit dropping the legacy callbacks from the
  tree.

  As the quest to pay back technical dept never really ends, we're
  starting another set of interface conversions, this time it's about
  moving fields specific to only a handful of drivers using the
  gpio-mmio helper out of the core gpio_chip structure that every
  controller implements and uses. This cycle we introduce a new set of
  APIs and convert a few drivers under drivers/gpio/, next cycle we'll
  convert remaining modules treewide (in gpio, pinctrl and mfd trees)
  and finally remove the old interfaces and move the gpio-mmio fields
  into their own structure wrapping gpio_chip.

  One last change I should mention here is the rework of the sysfs
  interface. In 2016, we introduced the GPIO character device as the
  preferred alternative to the sysfs class under /sys/class/gpio. While
  it has seen a wide adoption with the help of its user-space
  counterpart - libgpiod - there are still users who prefer the
  simplicity of sysfs.

  As far as the GPIO subsystem is concerned, the problem is not the
  existince of the GPIO class as such but rather the fact that it
  exposes the global GPIO numbers to the user-space, stopping us from
  ever being able to remove the numberspace from the kernel. To that
  end, this release we introduced a parallel, limited sysfs interface
  that doesn't expose these numbers and only implements a subset of
  features that are relevant to the existing users. This is a result of
  several discussions over the course of last year and should allow us
  to remove the legacy part some time in the future.

  Summary:

  GPIOLIB core:
   - introduce a parallel, limited sysfs user ABI that doesn't expose
     the global GPIO numbers to user-space while maintaining backward
     compatibility with the end goal of it completely replacing the
     existing interface, allowing us to remove it
   - remove the legacy devm_gpio_request() routine which has no more
     users

177bf8620c sound updates for 6.17-rc1
This includes lots of file shuffling due to HD-audio code
 reorganization and many trivial changes, but otherwise there shouldn't
 be much surprise from the functionality POV.  The PR includes the PM
 changes as prerequisite, too.  Some highlights below:
 
 Core:
 - Performance optimizations in PCM core code
 - Refactoring of ASoC Kconfig menus to be hopefully more consistant
   and easier to navigate.
 - Refactoring of ASoC DAPM code, mainly hiding functionality that
   doesn't need to be exposed to drivers
 
 HD-audio reorganization:
 - All code are moved under sound/hda with a bit more understandable
   tree structure, as well as file renames
 - The huge Realtek driver code is split to several parts, a common
   helper module with driver modules per probe entry
 - HDMI and Cirrus codec drivers also split
 
 ASoC:
 - Further work on the generic handling for SoundWire SDCA devices

Pull sound updates from Takashi Iwai:
 "This includes lots of file shuffling due to HD-audio code
  reorganization and many trivial changes, but otherwise there shouldn't
  be much surprise from the functionality POV. The PR includes the PM
  changes as prerequisite, too. Some highlights below:

  Core:
   - Performance optimizations in PCM core code
   - Refactoring of ASoC Kconfig menus to be hopefully more consistant
     and easier to navigate.
   - Refactoring of ASoC DAPM code, mainly hiding functionality that
     doesn't need to be exposed to drivers

  HD-audio reorganization:
   - All code are moved under sound/hda with a bit more understandable
     tree structure, as well as file renames
   - The huge Realtek driver code is split to several parts, a common
     helper module with driver modules per probe entry
   - HDMI and Cirrus codec drivers also split

  ASoC:
   - Further work on the generic handling for SoundWire SDCA devices
   - Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5,
     various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI
     TAS5753

13150742b0 Crypto library updates for 6.17
This is the main crypto library pull request for 6.17. The main focus
 this cycle is on reorganizing the SHA-1 and SHA-2 code, providing
 high-quality library APIs for SHA-1 and SHA-2 including HMAC support,
 and establishing conventions for lib/crypto/ going forward:
 
  - Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares
    most of the SHA-512 code) into lib/crypto/. This includes both the
    generic and architecture-optimized code. Greatly simplify how the
    architecture-optimized code is integrated. Add an easy-to-use
    library API for each SHA variant, including HMAC support. Finally,
    reimplement the crypto_shash support on top of the library API.
 
  - Apply the same reorganization to the SHA-256 code (and also SHA-224
    which shares most of the SHA-256 code). This is a somewhat smaller
    change, due to my earlier work on SHA-256. But this brings in all
    the same additional improvements that I made for SHA-1 and SHA-512.
 
 There are also some smaller changes:
 
  - Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code
    from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For
    these algorithms it's just a move, not a full reorganization yet.
 
  - Fix the MIPS chacha-core.S to build with the clang assembler.
 
  - Fix the Poly1305 functions to work in all contexts.
 
  - Fix a performance regression in the x86_64 Poly1305 code.
 
  - Clean up the x86_64 SHA-NI optimized SHA-1 assembly code.
 
 Note that since the new organization of the SHA code is much simpler,
 the diffstat of this pull request is negative, despite the addition of
 new fully-documented library APIs for multiple SHA and HMAC-SHA
 variants. These APIs will allow further simplifications across the
 kernel as users start using them instead of the old-school crypto API.
 (I've already written a lot of such conversion patches, removing over
 1000 more lines of code. But most of those will target 6.18 or later.)

a578dd095d CRC updates for 6.17
Updates for the kernel's CRC (cyclic redundancy check) code:
 
  - Reorganize the architecture-optimized CRC code. It now lives in
    lib/crc/$(SRCARCH)/ rather than arch/$(SRCARCH)/lib/, and it is no
    longer artificially split into separate generic and arch modules.
    This allows better inlining and dead code elimination. The generic
    CRC code is also no longer exported, simplifying the API. (This
    mirrors the similar changes to SHA-1 and SHA-2 in lib/crypto/,
    which can be found in the "Crypto library updates" pull request.)
 
  - Improve crc32c() performance on newer x86_64 CPUs on long messages
    by enabling the VPCLMULQDQ optimized code.
 
  - Simplify the crypto_shash wrappers for crc32_le() and crc32c().
    Register just one shash algorithm for each that uses the (fully
    optimized) library functions, instead of unnecessarily providing
    direct access to the generic CRC code.
 
  - Remove unused and obsolete drivers for hardware CRC engines.
 
  - Remove CRC-32 combination functions that are no longer used.
 
  - Add kerneldoc for crc32_le(), crc32_be(), and crc32c().
 
  - Convert the crc32() macro to an inline function.
