Pull MTD updates from Miquel Raynal:
 "MTD changes:

   - No particularly important patchset this cycle, but we have a few
     usual improvements: like using a better/more recent helper or
     checking a return value.

  Raw NAND changes:

   - The use of for_each_child_of_node_scoped() has been spread into the
     subsystem drivers

   - a couple of exit path have been fixed (mtk, denali)

   - TI GPMC bindings have been enhanced to comply with up-to-date
     partition descriptions

   - a load of small and misc fixes

  SPI-NAND changes:

   - The most impacting series this cycle is bringing support for
     continuous reads in the SPI-NAND subsystem.

     This is a feature already merged in the raw NAND subsystem which
     allows optimizing the internal fetch times in the chip while
     reading sequential pages within an eraseblock.

     For now only Macronix NANDs benefit from this feature. While we are
     talking about Macronix, some of their chip need an explicit action
     for selecting a different plane, and support for it has also been
     brought.

   - The bitflip threshold has also been set to the same arbitrary level
     as in the raw NAND subsystem to optimize wear leveling decisions

   - Add upport for a new Winbond chip

  SPI NOR changes:

   - Add Write Protect support for N25Q064A.

   - New flash support for Zetta ZD25Q128C and Spansion S28HS256T.

   - Fix a NULL dereference in probe path for flashes without a name.

     existence first. S28HS256T is the first flash to define its entry

Pull slab updates from Vlastimil Babka:
 "This time it's mostly refactoring and improving APIs for slab users in
  the kernel, along with some debugging improvements.

   - kmem_cache_create() refactoring (Christian Brauner)

     Over the years have been growing new parameters to
     kmem_cache_create() where most of them are needed only for a small
     number of caches - most recently the rcu_freeptr_offset parameter.

     To avoid adding new parameters to kmem_cache_create() and adjusting
     all its callers, or creating new wrappers such as
     kmem_cache_create_rcu(), we can now pass extra parameters using the
     new struct kmem_cache_args. Not explicitly initialized fields
     default to values interpreted as unused.

     kmem_cache_create() is for now a wrapper that works both with the
     new form: kmem_cache_create(name, object_size, args, flags) and the
     legacy form: kmem_cache_create(name, object_size, align, flags,
     ctor)

   - kmem_cache_destroy() waits for kfree_rcu()'s in flight (Vlastimil
     Babka, Uladislau Rezki)

     Since SLOB removal, kfree() is allowed for freeing objects
     allocated by kmem_cache_create(). By extension kfree_rcu() as
     allowed as well, which can allow converting simple call_rcu()
     callbacks that only do kmem_cache_free(), as there was never a
     kmem_cache_free_rcu() variant. However, for caches that can be
     destroyed e.g. on module removal, the cache owners knew to issue
     rcu_barrier() first to wait for the pending call_rcu()'s, and this
     is not sufficient for pending kfree_rcu()'s due to its internal
     batching optimizations. Ulad has provided a new
     kvfree_rcu_barrier() and to make the usage less error-prone,
     kmem_cache_destroy() calls it. Additionally, destroying
     SLAB_TYPESAFE_BY_RCU caches now again issues rcu_barrier()
     synchronously instead of using an async work, because the past
     motivation for async work no longer applies. Users of custom
     call_rcu() callbacks should however keep calling rcu_barrier()
     before cache destruction.

   - Debugging use-after-free in SLAB_TYPESAFE_BY_RCU caches (Jann Horn)

     Currently, KASAN cannot catch UAFs in such caches as it is legal to
     access them within a grace period, and we only track the grace
     period when trying to free the underlying slab page. The new
     CONFIG_SLUB_RCU_DEBUG option changes the freeing of individual
     object to be RCU-delayed, after which KASAN can poison them.

   - Delayed memcg charging (Shakeel Butt)

     In some cases, the memcg is uknown at allocation time, such as
     receiving network packets in softirq context. With
     kmem_cache_charge() these may be now charged later when the user
     and its memcg is known.

   - Misc fixes and improvements (Pedro Falcato, Axel Rasmussen,
     Christoph Lameter, Yan Zhen, Peng Fan, Xavier)"

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"

 "New SoC support for Broadcom bcm2712 (Raspberry Pi 5) and Renesas
  R9A09G057 (RZ/V2H(P)) and Qualcomm Snapdragon 414 (MSM8929), all three
  of these are variants of already supported chips, in particular the
  last one is almost identical to MSM8939.

  specifically keeps improving.

  The other new machines are:

   - eight new machines using various 64-bit Rockchips SoCs, both on the
     consumer/gaming side and developer boards

   - three industrial boards with 64-bit i.MX, which is a very low
     number for them.

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"
