Pull random number generator updates from Jason Donenfeld:
"Originally I'd planned on sending each of the vDSO getrandom()
architecture ports to their respective arch trees. But as we started
to work on this, we found lots of interesting issues in the shared
code and infrastructure, the fixes for which the various archs needed
to base their work.
So in the end, this turned into a nice collaborative effort fixing up
issues and porting to 5 new architectures -- arm64, powerpc64,
powerpc32, s390x, and loongarch64 -- with everybody pitching in and
commenting on each other's code. It was a fun development cycle.
This contains:
- Numerous fixups to the vDSO selftest infrastructure, getting it
running successfully on more platforms, and fixing bugs in it.
- Additions to the vDSO getrandom & chacha selftests. Basically every
time manual review unearthed a bug in a revision of an arch patch,
or an ambiguity, the tests were augmented.
By the time the last arch was submitted for review, s390x, v1 of
the series was essentially fine right out of the gate.
- Fixes to the the generic C implementation of vDSO getrandom, to
build and run successfully on all archs, decoupling it from
assumptions we had (unintentionally) made on x86_64 that didn't
carry through to the other architectures.
- Port of vDSO getrandom to LoongArch64, from Xi Ruoyao and acked by
Huacai Chen.
- Port of vDSO getrandom to ARM64, from Adhemerval Zanella and acked
by Will Deacon.
- Port of vDSO getrandom to PowerPC, in both 32-bit and 64-bit
varieties, from Christophe Leroy and acked by Michael Ellerman.
- Port of vDSO getrandom to S390X from Heiko Carstens, the arch
maintainer.
While it'd be natural for there to be things to fix up over the course
of the development cycle, these patches got a decent amount of review
from a fairly diverse crew of folks on the mailing lists, and, for the
most part, they've been cooking in linux-next, which has been helpful
for ironing out build issues.
In terms of architectures, I think that mostly takes care of the
important 64-bit archs with hardware still being produced and running
production loads in settings where vDSO getrandom is likely to help.
Arguably there's still RISC-V left, and we'll see for 6.13 whether
they find it useful and submit a port"

Performance events changes for v6.12:
- Implement per-PMU context rescheduling to significantly improve single-PMU
performance, and related cleanups/fixes. (by Peter Zijlstra and Namhyung Kim)
- Fix ancient bug resulting in a lot of events being dropped erroneously
at higher sampling frequencies. (by Luo Gengkun)
- uprobes enhancements:
- Implement RCU-protected hot path optimizations for better performance:
"For baseline vs SRCU, peak througput increased from 3.7 M/s (million uprobe
triggerings per second) up to about 8 M/s. For uretprobes it's a bit more
modest with bump from 2.4 M/s to 5 M/s.
For SRCU vs RCU Tasks Trace, peak throughput for uprobes increases further from
8 M/s to 10.3 M/s (+28%!), and for uretprobes from 5.3 M/s to 5.8 M/s (+11%),
as we have more work to do on uretprobes side.
Even single-thread (no contention) performance is slightly better: 3.276 M/s to
3.396 M/s (+3.5%) for uprobes, and 2.055 M/s to 2.174 M/s (+5.8%)
for uretprobes."
(by Andrii Nakryiko et al)
- Document mmap_lock, don't abuse get_user_pages_remote(). (by Oleg Nesterov)
- Cleanups & fixes to prepare for future work:
- Remove uprobe_register_refctr()
- Simplify error handling for alloc_uprobe()
- Make uprobe_register() return struct uprobe *
- Fold __uprobe_unregister() into uprobe_unregister()
- Shift put_uprobe() from delete_uprobe() to uprobe_unregister()
- BPF: Fix use-after-free in bpf_uprobe_multi_link_attach()
(by Oleg Nesterov)
- New feature & ABI extension: allow events to use PERF_SAMPLE READ with
inheritance, enabling sample based profiling of a group of counters over
a hierarchy of processes or threads. (by Ben Gainey)
- Intel uncore & power events updates:
- Add Arrow Lake and Lunar Lake support
- Add PERF_EV_CAP_READ_SCOPE
- Clean up and enhance cpumask and hotplug support
(by Kan Liang)
- Add LNL uncore iMC freerunning support
- Use D0:F0 as a default device
(by Zhenyu Wang)
- Intel PT: fix AUX snapshot handling race. (by Adrian Hunter)
- Misc fixes and cleanups. (by James Clark, Jiri Olsa, Oleg Nesterov and Peter Zijlstra)

pwm: Changes for v6.12-rc1
This pull request contains some cleanups to the core and some mostly minor updates to a bunch of drivers and device tree bindings. One thing worth pointing out is that it contains an immutable branch containing support for a new mfd chip (Analog Devices ADP5585) with several sub drivers. So expect to get the four affected commits also from my fellow MFD and GPIO maintainers. Thanks go to Andrew Kreimer, Clark Wang, Conor Dooley, David Lechner, Dmitry Rokosov, Frank Li, Geert Uytterhoeven, George Stark, Jiapeng Chong, Krzysztof Kozlowski, Laurent Pinchart, Liao Chen, Liu Ying, Rob Herring and Wolfram Sang for code contributions and reviews and to Lee Jones for preparing the above mentioned immutable branch. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmboM3AACgkQj4D7WH0S /k6IzQgAj+3B4F4UKPPI8jcQqRQGOWfjA365nIQmr1oeFYSGDILv4btU1TNV1MfH WLXMRXLQb4dng21J8IwIJ/qyndL+GjRj3KWxLHJa3+/gxf8YuGwWJlNjlxtrGXM/ 3JQ/aWqfgCf4KTRG3MoCTKc5fxtbHHWZ71kGdi6cchk1HggyBUH/7g85h/VkhCuc JpOC7CvDVmzTkTIltCbiVJQ4xO3zmsV2WgnsWUzN+41PUjqJmMLmhKjI6UdAYWlI B3qgCMXik153oYgaIw/BMtxFWa9e2ZxZ6hV+gx4tVQWbOtBPUxEqHpX2dt1fp5+h 7PQoKVWJycykdxmlOSGnjOl3RHVX5A== =VjPD -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux Pull pwm updates from Uwe Kleine-König: "This contains some cleanups to the core and some mostly minor updates to a bunch of drivers and device tree bindings.

* 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. Aside from that, a couple of exit path have been
fixed (mtk, denali), the TI GPMC bindings have been enhanced to comply
with up-to-date partition descriptions and as always there is 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, and
finally support for a new Winbond chip has been added.
* SPI NOR changes
Notable 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. The
probe path tries to access the name without checking its existence
first. S28HS256T is the first flash to define its entry without a
name, uncovering this issue.

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)"

Not included in this pull request are a couple of more commits from Puranjay Mohan adding more atomic operations to LKMM, but these await a herdtools7 release that includes tool-side support for this functionality.

sound updates for 6.12-rc1
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

Merge tag 'sound-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
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"

Updates for x86 timers:
- Use the topology information of number of packages for making the
decision about TSC trust instead of using the number of online nodes
which is not reflecting the real topology.
- Stop the PIT timer 0 when its not in use as to stop pointless emulation
in the VMM.
- Fix the PIT timer stop sequence for timer 0 so it truly stops both real
hardware and buggy VMM emulations.

Updates for x86 memory management:
- 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.

Updates for x86 FRED:
- Enable FRED right after init_mem_mapping() because at that point the
early IDT fault handler is replaced by the real fault handler. The real
fault handler retrieves the faulting address from the stack 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.
- Set SS to __KERNEL_DS when enabling FRED to prevent a corner case where
ERETS can observe a SS mismatch and raises a #GP.

Updates for the x86 APIC code:
- 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.
- Code and comment cleanups in the APIC area.

- Fixup the KCOV Makefile directive which got stale due to a source file
rename
- Exclude stack unwinding from KCOV as it creates large amounts of
uninteresting coverage
- Provide a self test to validate that KCOV coverage of the interrupt
handling code starts not before preempt count got updated.

soc: driver updates for 6.12
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.

soc: devicetree updates for 6.12
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.
Lots of updates to Mediatek, ASpeed, Rockchips, Amlogic, Qualcomm,
STM32, NXP i.MX, Sophgo, TI K3, Renesas, Microchip at91, NVIDIA Tegra,
and T-HEAD.
The added Qualcomm platform support once again dominates the changes,
with seven phones and three laptops getting added in addition to
many new features on existing machines. The Snapdragon X1E support
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.
- four more servers using a 32-bit Speed BMC
- three boards using STM32MP1 SoCs
- one new machine each using allwinner, amlogic, broadcom
and renesas chips.

spi: Updates for v6.12
This is quite a quiet release for sPI. The one new core feature here is
support for configuring the state of the MOSI pin when the bus is idle,
there are some devices which are very fragile in this regard even when
the chip select signal is not asserted. Otherwise we have some new
driver support, a bunch of small fixes and some general cleanup work.
- Support for configuring the state of the MOSI pin when the the bus is
idle.
- Add the Elgin JG0309-01 in spidev.
- Support for Marvell xSPI, Mediatek MTK7981, Microchip PIC64GX,
NXP i.MX8ULP, and Rockchip RK3576 controllers.
I also accidentally pulled in an IIO DT bindings update due to a typo
when applying the MOSI idle state patches.

This release is almost all cleanup work of various kinds, while the
diffstat for the core is quite large this is almost all cleanups and
documentation improvments with some small fixes rather than any new
feature work. We do have support for a couple of new devices but these
are small additions to existing drivers rather than new drivers.
- Removal of the SM5703 driver which does not have it's dependencies
available.
- Support for Allwinner AXP717, and Qualcomm WCN6855.
The Allwinner support shares some commits with the MFD tree.

regmap: Updates for v6.12
The main update here is Matti's work allowing regmap irqdomains to be given custom names (allowing multiple interrupt controllers associatd with a single struct device), this pulls in some commits from Thomas' tree which it depends on. Otherwise there's a bit of work on improving handling of regmaps protected with spinlocks when used with complex cache types, fixing some valid but harmless lockdep reports seen with some new driver work. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmbnZjcACgkQJNaLcl1U h9CFMwf/ecsvvRV4LycfWvm3yehorg+ruV8TXFB/KswXZ957rWfxOYBrSdOoNezy nYb2LZAKWlS10Akk5CinBc/ZjRH1EQmjWCl/l2eKe1gTFQ9xPFGWNg7FlnmRRNKR 9SiBdSCjxXS55nZN7t4jeXCXUr8iaezV+K55rKdznpe/EOi19wHmNtR2+3PqtnuJ felae4Xrq3o+O20yV54KYq1iQNY2jNNFGZUGBYAzQjR8aCuY9lQATT36uTxqspWY icZwUiLCmmoRLTC+QbSnmjv26s/uURpRXR7BUhX40PaK6MuWzNHAjxUo8iYVzuVg Nmqw+5yeDF4tY9pDODrmqxK2fErObw== =TyFs -----END PGP SIGNATURE----- Merge tag 'regmap-v6.12' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "The main update here is Matti's work allowing regmap irqdomains to be given custom names (allowing multiple interrupt controllers associatd with a single struct device), this pulls in some commits from Thomas' tree which it depends on.
