Pull sound updates from Takashi Iwai:
 "A fairly big update at this time, both in core and driver sides.

  The core received rewrites in PCM buffer allocation handling and
  locking optimizations, PCM rate updates followed by lots of cleanups.

  In ASoC side, the legacy Intel drivers have been deprecated by AVS
  drivers which leaded to the significant amount of code reduction.
  SoundWire driver updates and other cleanups contributed more code
  reduction, too.

  USB-audio driver received a large cleanup of its big quirk table, and
  the old snd_print*() API usages in many legacy drivers are replaced
  with the standard print API.

  Here are some highlights:

  Core:
   - More optimized locking in ALSA control code
   - Rewrites of memalloc helpers for better DMA API usage
   - Drop of obsoleted vmalloc PCM buffer helper API
   - Continued MIDI2 UMP updates
   - Support of a new user-space driven timer instance
   - Update for more PCM support rates and cleanups
   - Xrun counter report in the proc files

  ASoC:
   - Continued simplification and cleanup works for ASoC
   - Extensive cleanups and refactoring of the Soundwire drivers
   - Removal of Intel machine support obsoleted by the AVS driver
   - Lots of DT schema conversions
   - Machine support for many AMD and Intel x86 platforms
   - Support for AMD ACP 7.1, Mediatek MT6367 and MT8365, Realtek
     RTL1320 SoundWire and rev C, and Texas Instruments TAS2563

  USB-audio:
   - Add support of multiple control interfaces
   - A large rewrite of quirk table with macros
   - Support for RME Digiface USB

  HD-audio:
   - Cleanup of quirk code for Samsung Galaxy laptops
   - Clean up of detection of Cirrus codecs
   - C-Media CM9825 HD-audio codec support

  Others:
   - Rewrites to standard print API in a lot of legacy drivers"

Pull x86 memory management updates from Thomas Gleixner:

 - Make LAM enablement safe vs. kernel threads using a process mm
   temporarily as switching back to the process would not update CR3 and
   therefore not enable LAM causing faults in user space when using
   tagged pointers. Cure it by synchronizing LAM enablement via IPIs to
   all CPUs which use the related mm.

 - Cure a LAM harmless inconsistency between CR3 and the state during
   context switch. It's both confusing and prone to lead to real bugs

 - Handle alt stack handling for threads which run with a non-zero
   protection key. The non-zero key prevents the kernel to access the
   alternate stack. Cure it by temporarily enabling all protection keys
   for the alternate stack setup/restore operations.

 - Provide a EFI config table identity mapping for kexec kernel to
   prevent kexec fails because the new kernel cannot access the config
   table array

 - Use GB pages only when a full GB is mapped in the identity map as
   otherwise the CPU can speculate into reserved areas after the end of
   memory which causes malfunction on UV systems.

 - Remove the noisy and pointless SRAT table dump during boot

 - Use is_ioremap_addr() for iounmap() address range checks instead of
   high_memory. is_ioremap_addr() is more precise.

Pull x86 FRED updates from Thomas Gleixner:

 - Enable FRED right after init_mem_mapping() because at that point the

   frame and not from CR2 when the FRED feature is set. But that
   obviously only works when FRED is enabled in the CPU as well.

Pull x86 APIC updates from Thomas Gleixner:

 - Handle an allocation failure in the IO/APIC code gracefully instead
   of crashing the machine.

 - Remove support for APIC local destination mode on 64bit

   Logical destination mode of the local APIC is used for systems with
   up to 8 CPUs. It has an advantage over physical destination mode as
   it allows to target multiple CPUs at once with IPIs. That advantage
   was definitely worth it when systems with up to 8 CPUs were state of
   the art for servers and workstations, but that's history.

   In the recent past there were quite some reports of new laptops
   failing to boot with logical destination mode, but they work fine
   with physical destination mode. That's not a suprise because physical
   destination mode is guaranteed to work as it's the only way to get a
   CPU up and running via the INIT/INIT/STARTUP sequence. Some of the
   affected systems were cured by BIOS updates, but not all OEMs provide
   them.

   As the number of CPUs keep increasing, logical destination mode
   becomes less used and the benefit for small systems, like laptops, is
   not really worth the trouble. So just remove logical destination mode
   support for 64bit and be done with it.

Pull SoC driver updates from Arnd Bergmann:
 "The driver updates seem larger this time around, with changes is many
  of the SoC specific drivers, both the custom drivers/soc ones and the
  closely related subsystems (memory, bus, firmware, reset, ...).

  The at91 platform gains support for sam9x7 chips in the soc and power
  management code. This is the latest variant of one of the oldest still
  supported SoC families, using the ARM9 (ARMv5) core.

  As usual, the qualcomm snapdragon platform gets a ton of updates in
  many of their drivers to add more features and additional SoC support.
  Most of these are somewhat firmware related as the platform has a
  number of firmware based interfaces to the kernel. A notable addition
  here is the inclusion of trace events to two of these drivers.

  Herve Codina and Christophe Leroy are now sending updates for
  drivers/soc/fsl/ code through the SoC tree, this contains both PowerPC
  and Arm specific platforms and has previously been problematic to
  maintain. The first update here contains support for newer PowerPC
  variants and some cleanups.

  The turris mox firmware driver has a number of updates, mostly
  cleanups.

  The Arm SCMI firmware driver gets a major rework to modularize the
  existing code into separately loadable drivers for the various
  transports, the addition of custom NXP i.MX9 interfaces and a number
  of smaller updates.

  The Arm FF-A firmware driver gets a feature update to support the v1.2
  version of the specification.

  The reset controller drivers have some smaller cleanups and a newly
  added driver for the Intel/Mobileye EyeQ5/EyeQ6 MIPS SoCs.

  The memory controller drivers get some cleanups and refactoring for
  Tegra, TI, Freescale/NXP and a couple more platforms.

  Finally there are lots of minor updates to firmware (raspberry pi,
  tegra, imx), bus (sunxi, omap, tegra) and soc (rockchips, tegra,
  amlogic, mediatek) drivers and their DT bindings"

Pull printk updates from Petr Mladek:
 "This is the "last" part of the support for the new nbcon consoles.
  Where "nbcon" stays for "No Big console lock CONsoles" aka not under
  the console_lock.

  New callbacks are added to struct console:

   - write_thread() for flushing nbcon consoles in task context.

   - write_atomic() for flushing nbcon consoles in atomic context,
     including NMI.

   - con->device_lock() and device_unlock() for taking the driver
     specific lock, for example, port->lock.

  New printk-specific kthreads are created:

   - per-console kthreads which get responsible for flushing normal
     priority messages on nbcon consoles.

   - thread which gets responsible for flushing normal priority messages
     on all consoles when CONFIG_RT enabled.

  The new callbacks are called under a special per-console lock which
  has already been added back in v6.7. It allows to distinguish three
  severities: normal, emergency, and panic. A context with a higher
  priority could take over the ownership when it is safe even in the
  middle of handling a record. The panic context could do it even when
  it is not safe. But it is allowed only for the final desperate flush
  before entering the infinite loop.

  The new lock helps to flush the messages directly in emergency and
  panic contexts. But it is not enough in all situations:

   - console_lock() is still need for synchronization against boot
     consoles.

   - con->device_lock() is need for synchronization against other
     operations on the same HW, e.g. serial port speed setting,
     non-printk related read/write.

  The dependency on con->device_lock() is mutual. Any code taking the
  driver specific lock has to acquire the related nbcon console context
  as well. For example, see the new uart_port_lock() API. It provides
  the necessary synchronization against emergency and panic contexts
  where the messages are flushed only under the new per-console lock.

  Maybe surprisingly, a quite tricky part is the decision how to flush
  the consoles in various situations. It has to take into account:

   - message priority:    normal, emergency, panic

   - scheduling context:  task, atomic, deferred_legacy

   - registered consoles: boot, legacy, nbcon

   - threads are running: early boot, suspend, shutdown, panic

   - caller:              printk(), pr_flush(), printk_flush_in_panic(),
                          console_unlock(), console_start(), ...

  The primary decision is made in printk_get_console_flush_type(). It
  creates a hint what the caller should do:

   - flush nbcon consoles directly or via the kthread

   - call the legacy loop (console_unlock()) directly or via irq_work

  The existing behavior is preserved for the legacy consoles. The only
  exception is that they are not longer flushed directly from printk()
  in panic() before CPUs are stopped. But this blocking happens only
  when at least one nbcon console is registered. The motivation is to
  increase a chance to produce the crash dump. They legacy consoles
  might create a deadlock in compare with nbcon consoles. The nbcon
  console should allow to see the messages even when the crash dump
  fails.

  There are three possible ways how nbcon consoles are flushed:

   - The per-nbcon-console kthread is responsible for flushing messages
     added with the normal priority. This is the default mode.

   - The legacy loop, aka console_unlock(), is used when there is still
     a boot console registered. There is no easy way how to match an
     early console driver with a nbcon console driver. And the
     console_lock() provides the only reliable serialization at the
     moment.

     The legacy loop uses either con->write_atomic() or
     con->write_thread() callbacks depending on whether it is allowed to
     schedule. The atomic variant has to be used from printk().

   - In other situations, the messages are flushed directly using
     write_atomic() which can be called in any context, including NMI.
     It is primary needed during early boot or shutdown, in emergency
     situations, and panic.

  The emergency priority is used by a code called within
  nbcon_cpu_emergency_enter()/exit(). At the moment, it is used in four
  situations: WARN(), Oops, lockdep, and RCU stall reports.

  Finally, there is no nbcon console at the moment. It means that the
  changes should _not_ modify the existing behavior. The only exception
  is CONFIG_RT which would force offloading the legacy loop, for normal
  priority context, into the dedicated kthread"

Pull lsm updates from Paul Moore:

 - Move the LSM framework to static calls

   This transitions the vast majority of the LSM callbacks into static
   calls. Those callbacks which haven't been converted were left as-is
   due to the general ugliness of the changes required to support the
   static call conversion; we can revisit those callbacks at a future
   date.

 - Add the Integrity Policy Enforcement (IPE) LSM

   This adds a new LSM, Integrity Policy Enforcement (IPE). There is
   plenty of documentation about IPE in this patches, so I'll refrain
   from going into too much detail here, but the basic motivation behind
   IPE is to provide a mechanism such that administrators can restrict
   execution to only those binaries which come from integrity protected
   storage, e.g. a dm-verity protected filesystem. You will notice that
   IPE requires additional LSM hooks in the initramfs, dm-verity, and
   fs-verity code, with the associated patches carrying ACK/review tags
   from the associated maintainers. We couldn't find an obvious
   maintainer for the initramfs code, but the IPE patchset has been
   widely posted over several years.

   Both Deven Bowers and Fan Wu have contributed to IPE's development
   over the past several years, with Fan Wu agreeing to serve as the IPE
   maintainer moving forward. Once IPE is accepted into your tree, I'll
   start working with Fan to ensure he has the necessary accounts, keys,
   etc. so that he can start submitting IPE pull requests to you
   directly during the next merge window.

 - Move the lifecycle management of the LSM blobs to the LSM framework

   Management of the LSM blobs (the LSM state buffers attached to
   various kernel structs, typically via a void pointer named "security"
   or similar) has been mixed, some blobs were allocated/managed by
   individual LSMs, others were managed by the LSM framework itself.

   Starting with this pull we move management of all the LSM blobs,
   minus the XFRM blob, into the framework itself, improving consistency
   across LSMs, and reducing the amount of duplicated code across LSMs.
   Due to some additional work required to migrate the XFRM blob, it has
   been left as a todo item for a later date; from a practical
   standpoint this omission should have little impact as only SELinux
   provides a XFRM LSM implementation.

 - Fix problems with the LSM's handling of F_SETOWN

   The LSM hook for the fcntl(F_SETOWN) operation had a couple of
   problems: it was racy with itself, and it was disconnected from the
   associated DAC related logic in such a way that the LSM state could
   be updated in cases where the DAC state would not. We fix both of
   these problems by moving the security_file_set_fowner() hook into the
   same section of code where the DAC attributes are updated. Not only
   does this resolve the DAC/LSM synchronization issue, but as that code
   block is protected by a lock, it also resolve the race condition.

 - Fix potential problems with the security_inode_free() LSM hook

   Due to use of RCU to protect inodes and the placement of the LSM hook
   associated with freeing the inode, there is a bit of a challenge when
   it comes to managing any LSM state associated with an inode. The VFS
   folks are not open to relocating the LSM hook so we have to get
   creative when it comes to releasing an inode's LSM state.
   Traditionally we have used a single LSM callback within the hook that
   is triggered when the inode is "marked for death", but not actually
   released due to RCU.

   Unfortunately, this causes problems for LSMs which want to take an
   action when the inode's associated LSM state is actually released; so
   we add an additional LSM callback, inode_free_security_rcu(), that is
   called when the inode's LSM state is released in the RCU free
   callback.

 - Refactor two LSM hooks to better fit the LSM return value patterns

   The vast majority of the LSM hooks follow the "return 0 on success,
   negative values on failure" pattern, however, there are a small
   handful that have unique return value behaviors which has caused
   confusion in the past and makes it difficult for the BPF verifier to
   properly vet BPF LSM programs. This includes patches to
   convert two of these"special" LSM hooks to the common 0/-ERRNO pattern.

 - Various cleanups and improvements

   A handful of patches to remove redundant code, better leverage the
   IS_ERR_OR_NULL() helper, add missing "static" markings, and do some

Pull selinux updates from Paul Moore:

 - Ensure that both IPv4 and IPv6 connections are properly initialized

   While we always properly initialized IPv4 connections early in their
   life, we missed the necessary IPv6 change when we were adding IPv6
   support.

 - Annotate the SELinux inode revalidation function to quiet KCSAN

   KCSAN correctly identifies a race in __inode_security_revalidate()
   when we check to see if an inode's SELinux has been properly
   initialized. While KCSAN is correct, it is an intentional choice made
   for performance reasons; if necessary, we check the state a second
   time, this time with a lock held, before initializing the inode's
   state.

 - Code cleanups, simplification, etc.

   A handful of individual patches to simplify some SELinux kernel
   logic, improve return code granularity via ERR_PTR(), follow the
   guidance on using KMEM_CACHE(), and correct some minor style
   problems.

Pull audit updates from Paul Moore:

 - Fix some remaining problems with PID/TGID reporting

   When most users think about PIDs, what they are really thinking about
   is the TGID. This commit shifts the audit PID logging and filtering
   to use the TGID value which should provide a more meaningful audit
   stream and filtering experience for users.

 - Migrate to the str_enabled_disabled() helper

   Evidently we have helper functions that help ensure if we mistype
   "enabled" or "disabled" it is now caught at compile time. I guess
   we're fancy now.

Fix an upstream merge resolution issue[1].  The NETFS_SREQ_HIT_EOF flag,
and code to set it, got added via two different paths.  The original path
saw it added in the netfslib read improvements[2], but it was also added,
and slightly differently, in a fix that was committed before v6.11:

        1da29f2c
        netfs, cifs: Fix handling of short DIO read

However, the code added to smb2_readv_callback() to set the flag in didn't
get removed when the netfs read improvements series was rebased to take
account of the cifs fixes.  The proposed merge resolution[2] deleted it
rather than rebase the patches.

Fix this by removing the redundant lines.  Code to set the bit that derives
from the fix patch is still there, a few lines above in the source.

Fix an upstream merge resolution issue[1].  Prior to the netfs read
healpers, the SMB1 asynchronous read callback, cifs_readv_worker()
performed the cleanup for the operation in the network message processing
loop, potentially slowing down the processing of incoming SMB messages.

With commit a68c7486 ("cifs: Fix SMB1 readv/writev callback in the same
way as SMB2/3"), this was moved to a worker thread (as is done in the
SMB2/3 transport variant).  However, the "was_async" argument to
netfs_subreq_terminated (which was originally incorrectly "false" got
flipped to "true" - which was then incorrect because, being in a kernel
thread, it's not in an async context).

This got corrected in the sample merge[2], but Linus, not unreasonably,
switched it back to its previous value.

Note that this value tells netfslib whether or not it can run sleepable
stuff or stuff that takes a long time, such as retries and cleanups, in the
calling thread, or whether it should offload to a worker thread.

Fix this so that it is "false".  The callback to netfslib in both SMB1 and
SMB2/3 now gets offloaded from the network message thread to a separate
worker thread and thus it's fine to do the slow work in this thread.

Pull io_uring async discard support from Jens Axboe:
 "Sitting on top of both the 6.12 block and io_uring core branches,
  here's support for async discard through io_uring.

  This allows applications to issue async discards, rather than rely on
  the blocking sync ioctl discards we already have. The sync support is
  difficult to use outside of idle/cleanup periods.

  On a real (but slow) device, testing shows the following results when
  compared to sync discard:

	qd64 sync discard: 21K IOPS, lat avg 3 msec (max 21 msec)
	qd64 async discard: 76K IOPS, lat avg 845 usec (max 2.2 msec)

	qd64 sync discard: 14K IOPS, lat avg 5 msec (max 25 msec)
	qd64 async discard: 56K IOPS, lat avg 1153 usec (max 3.6 msec)

  and synthetic null_blk testing with the same queue depth and block
  size settings as above shows:

	Type    Trim size       IOPS    Lat avg (usec)  Lat Max (usec)
	==============================================================
	sync    4k               144K       444            20314
	async   4k              1353K        47              595
	sync    1M                56K      1136            21031
