git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull parisc architecture updates from Helge Deller:
- On parisc we now use the generic clockevent framework for timekeeping
- Although there is no 64-bit glibc/userspace for parisc yet, for
testing purposes one can run statically linked 64-bit binaries. This
patchset contains two patches which fix 64-bit userspace which has
been broken since kernel 4.19
- Fix the userspace stack position and size when the ADDR_NO_RANDOMIZE
personality is enabled
- On other architectures mmap(MAP_GROWSDOWN | MAP_STACK) creates a
downward-growing stack. On parisc mmap(MAP_STACK) is now sufficient
to create an upward-growing stack
* tag 'parisc-for-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Allow mmap(MAP_STACK) memory to automatically expand upwards
parisc: Use PRIV_USER instead of hardcoded value
parisc: Fix itlb miss handler for 64-bit programs
parisc: Fix 64-bit userspace syscall path
parisc: Fix stack start for ADDR_NO_RANDOMIZE personality
parisc: Convert to generic clockevents

Pull xfs updates from Chandan Babu:
"New code:
- Introduce new ioctls to exchange contents of two files.
The first ioctl does the preparation work to exchange the contents
of two files while the second ioctl performs the actual exchange if
the target file has not been changed since a given sampling point.
Fixes:
- Fix bugs associated with calculating the maximum range of realtime
extents to scan for free space.
- Copy keys instead of records when resizing the incore BMBT root
block.
- Do not report FITRIMming more bytes than possibly exist in the
filesystem.
- Modify xfs_fs.h to prevent C++ compilation errors.
- Do not over eagerly free post-EOF speculative preallocation.
- Ensure st_blocks never goes to zero during COW writes
Cleanups/refactors:
- Use Xarray to hold per-AG data instead of a Radix tree.
- Cleanups to:
- realtime bitmap
- inode allocator
- quota
- inode rooted btree code"

git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
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"

Pull perf events updates from Ingo Molnar:
- Implement per-PMU context rescheduling to significantly improve
single-PMU performance, and related cleanups/fixes (Peter Zijlstra
and Namhyung Kim)
- Fix ancient bug resulting in a lot of events being dropped
erroneously at higher sampling frequencies (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."

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.
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)"

- cpuset cgroup1 support is split into its own file behind the new
config option CONFIG_CPUSET_V1. This makes it the second controller
which makes cgroup1 support optional after memcg
- Handling of unavailable v1 controller handling improved during
cgroup1 mount operations
- union_find applied to cpuset. It makes code simpler and more
efficient

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
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.

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.
