Pull scheduler updates from Ingo Molnar:
- Implement persistent user-requested affinity: introduce
affinity_context::user_mask and unconditionally preserve the
user-requested CPU affinity masks, for long-lived tasks to better
interact with cpusets & CPU hotplug events over longer timespans,
without destroying the original affinity intent if the underlying
topology changes.

Pull perf events updates from Ingo Molnar:
- Thoroughly rewrite the data structures that implement perf task
context handling, with the goal of fixing various quirks and
unfeatures both in already merged, and in upcoming proposed code.
The old data structure is the per task and per cpu
perf_event_contexts:
task_struct::perf_events_ctxp[] <-> perf_event_context <-> perf_cpu_context
^ | ^ | ^
`---------------------------------' | `--> pmu ---'
v ^
perf_event ------'
In this new design this is replaced with a single task context and a
single CPU context, plus intermediate data-structures:
task_struct::perf_event_ctxp -> perf_event_context <- perf_cpu_context
^ | ^ ^
`---------------------------' | |
| | perf_cpu_pmu_context <--.
| `----. ^ |
| | | |
| v v |
| ,--> perf_event_pmu_context |
| | |
| | |
v v |
perf_event ---> pmu ----------------'
[ See commit bd2756811766 for more details. ]

Pull x86 fpu updates from Dave Hansen:
"There are two little fixes in here, one to give better XSAVE warnings
and another to address some undefined behavior in offsetof().
There is also a collection of patches to fix some issues with ptrace
and the protection keys register (PKRU). PKRU is a real oddity because
it is exposed in the XSAVE-related ABIs, but it is generally managed
without using XSAVE in the kernel. This fix thankfully came with a
selftest to ward off future regressions.

- Clarify XSAVE consistency warnings
- Fix up ptrace interface to protection keys register (PKRU)
- Avoid undefined compiler behavior with TYPE_ALIGN"

Pull cxl updates from Dan Williams:
"Compute Express Link (CXL) updates for 6.2.
While it may seem backwards, the CXL update this time around includes
some focus on CXL 1.x enabling where the work to date had been with
CXL 2.0 (VH topologies) in mind.
First generation CXL can mostly be supported via BIOS, similar to DDR,
however it became clear there are use cases for OS native CXL error
handling and some CXL 3.0 endpoint features can be deployed on CXL 1.x
hosts (Restricted CXL Host (RCH) topologies). So, this update brings
RCH topologies into the Linux CXL device model.
In support of the ongoing CXL 2.0+ enabling two new core kernel
facilities are added.
One is the ability for the kernel to flag collisions between userspace
access to PCI configuration registers and kernel accesses. This is
brought on by the PCIe Data-Object-Exchange (DOE) facility, a hardware
mailbox over config-cycles.
The other is a cpu_cache_invalidate_memregion() API that maps to
wbinvd_on_all_cpus() on x86. To prevent abuse it is disabled in guest
VMs and architectures that do not support it yet. The CXL paths that
need it, dynamic memory region creation and security commands (erase /
unlock), are disabled when it is not present.
As for the CXL 2.0+ this cycle the subsystem gains support Persistent
Memory Security commands, error handling in response to PCIe AER
notifications, and support for the "XOR" host bridge interleave
algorithm.
Summary:
- Add the cpu_cache_invalidate_memregion() API for cache flushing in
response to physical memory reconfiguration, or memory-side data
invalidation from operations like secure erase or memory-device
unlock.
- Add a facility for the kernel to warn about collisions between
kernel and userspace access to PCI configuration registers
- Add support for Restricted CXL Host (RCH) topologies (formerly CXL
1.1)
- Add handling and reporting of CXL errors reported via the PCIe AER
mechanism
- Add support for CXL Persistent Memory Security commands
- Add support for the "XOR" algorithm for CXL host bridge interleave
- Rework / simplify CXL to NVDIMM interactions
- Miscellaneous cleanups and fixes"

Pull timer updates from Thomas Gleixner:
"Updates for timers, timekeeping and drivers:
Core:
- The timer_shutdown[_sync]() infrastructure:
Tearing down timers can be tedious when there are circular
dependencies to other things which need to be torn down. A prime
example is timer and workqueue where the timer schedules work and
the work arms the timer.
What needs to prevented is that pending work which is drained via
destroy_workqueue() does not rearm the previously shutdown timer.
Nothing in that shutdown sequence relies on the timer being
functional.
The conclusion was that the semantics of timer_shutdown_sync()
should be:
- timer is not enqueued
- timer callback is not running
- timer cannot be rearmed
Preventing the rearming of shutdown timers is done by discarding
rearm attempts silently.
A warning for the case that a rearm attempt of a shutdown timer is
detected would not be really helpful because it's entirely unclear
how it should be acted upon. The only way to address such a case is
to add 'if (in_shutdown)' conditionals all over the place. This is
error prone and in most cases of teardown not required all.
- The real fix for the bluetooth HCI teardown based on
timer_shutdown_sync().
A larger scale conversion to timer_shutdown_sync() is work in
progress.
- Consolidation of VDSO time namespace helper functions
- Small fixes for timer and timerqueue
Drivers:
- Prevent integer overflow on the XGene-1 TVAL register which causes
an never ending interrupt storm.
- The usual set of new device tree bindings
- Small fixes and improvements all over the place"

Pull irq updates from Thomas Gleixner:
"Updates for the interrupt core and driver subsystem:
The bulk is the rework of the MSI subsystem to support per device MSI
interrupt domains. This solves conceptual problems of the current
PCI/MSI design which are in the way of providing support for
PCI/MSI[-X] and the upcoming PCI/IMS mechanism on the same device.
IMS (Interrupt Message Store] is a new specification which allows
device manufactures to provide implementation defined storage for MSI
messages (as opposed to PCI/MSI and PCI/MSI-X that has a specified
message store which is uniform accross all devices). The PCI/MSI[-X]
uniformity allowed us to get away with "global" PCI/MSI domains.
IMS not only allows to overcome the size limitations of the MSI-X
table, but also gives the device manufacturer the freedom to store the
message in arbitrary places, even in host memory which is shared with
the device.
There have been several attempts to glue this into the current MSI
code, but after lengthy discussions it turned out that there is a
fundamental design problem in the current PCI/MSI-X implementation.
This needs some historical background.
When PCI/MSI[-X] support was added around 2003, interrupt management
was completely different from what we have today in the actively
developed architectures. Interrupt management was completely
architecture specific and while there were attempts to create common
infrastructure the commonalities were rudimentary and just providing
shared data structures and interfaces so that drivers could be written
in an architecture agnostic way.
The initial PCI/MSI[-X] support obviously plugged into this model
which resulted in some basic shared infrastructure in the PCI core
code for setting up MSI descriptors, which are a pure software
construct for holding data relevant for a particular MSI interrupt,
but the actual association to Linux interrupts was completely
architecture specific. This model is still supported today to keep
museum architectures and notorious stragglers alive.
In 2013 Intel tried to add support for hot-pluggable IO/APICs to the
kernel, which was creating yet another architecture specific mechanism
and resulted in an unholy mess on top of the existing horrors of x86
interrupt handling. The x86 interrupt management code was already an
incomprehensible maze of indirections between the CPU vector
management, interrupt remapping and the actual IO/APIC and PCI/MSI[-X]
implementation.
At roughly the same time ARM struggled with the ever growing SoC
specific extensions which were glued on top of the architected GIC
interrupt controller.
This resulted in a fundamental redesign of interrupt management and
provided the today prevailing concept of hierarchical interrupt
domains. This allowed to disentangle the interactions between x86
vector domain and interrupt remapping and also allowed ARM to handle
the zoo of SoC specific interrupt components in a sane way.
The concept of hierarchical interrupt domains aims to encapsulate the
functionality of particular IP blocks which are involved in interrupt
delivery so that they become extensible and pluggable. The X86
encapsulation looks like this:
|--- device 1
[Vector]---[Remapping]---[PCI/MSI]--|...
|--- device N
where the remapping domain is an optional component and in case that
it is not available the PCI/MSI[-X] domains have the vector domain as
their parent. This reduced the required interaction between the
domains pretty much to the initialization phase where it is obviously
required to establish the proper parent relation ship in the
components of the hierarchy.
While in most cases the model is strictly representing the chain of IP
blocks and abstracting them so they can be plugged together to form a
hierarchy, the design stopped short on PCI/MSI[-X]. Looking at the
hardware it's clear that the actual PCI/MSI[-X] interrupt controller
is not a global entity, but strict a per PCI device entity.
Here we took a short cut on the hierarchical model and went for the
easy solution of providing "global" PCI/MSI domains which was possible
because the PCI/MSI[-X] handling is uniform across the devices. This
also allowed to keep the existing PCI/MSI[-X] infrastructure mostly
unchanged which in turn made it simple to keep the existing
architecture specific management alive.
A similar problem was created in the ARM world with support for IP
block specific message storage. Instead of going all the way to stack
a IP block specific domain on top of the generic MSI domain this ended
in a construct which provides a "global" platform MSI domain which
allows overriding the irq_write_msi_msg() callback per allocation.
In course of the lengthy discussions we identified other abuse of the
MSI infrastructure in wireless drivers, NTB etc. where support for
implementation specific message storage was just mindlessly glued into
the existing infrastructure. Some of this just works by chance on
particular platforms but will fail in hard to diagnose ways when the
driver is used on platforms where the underlying MSI interrupt
management code does not expect the creative abuse.
Another shortcoming of today's PCI/MSI-X support is the inability to
allocate or free individual vectors after the initial enablement of
MSI-X. This results in an works by chance implementation of VFIO (PCI
pass-through) where interrupts on the host side are not set up upfront
to avoid resource exhaustion. They are expanded at run-time when the
guest actually tries to use them. The way how this is implemented is
that the host disables MSI-X and then re-enables it with a larger
number of vectors again. That works by chance because most device
drivers set up all interrupts before the device actually will utilize
them. But that's not universally true because some drivers allocate a
large enough number of vectors but do not utilize them until it's
actually required, e.g. for acceleration support. But at that point
other interrupts of the device might be in active use and the MSI-X
disable/enable dance can just result in losing interrupts and
therefore hard to diagnose subtle problems.
Last but not least the "global" PCI/MSI-X domain approach prevents to
utilize PCI/MSI[-X] and PCI/IMS on the same device due to the fact
that IMS is not longer providing a uniform storage and configuration
model.
The solution to this is to implement the missing step and switch from
global PCI/MSI domains to per device PCI/MSI domains. The resulting
hierarchy then looks like this:
|--- [PCI/MSI] device 1
[Vector]---[Remapping]---|...
|--- [PCI/MSI] device N
which in turn allows to provide support for multiple domains per
device:
|--- [PCI/MSI] device 1
|--- [PCI/IMS] device 1
[Vector]---[Remapping]---|...
|--- [PCI/MSI] device N
|--- [PCI/IMS] device N
This work converts the MSI and PCI/MSI core and the x86 interrupt
domains to the new model, provides new interfaces for post-enable
allocation/free of MSI-X interrupts and the base framework for
PCI/IMS. PCI/IMS has been verified with the work in progress IDXD
driver.
There is work in progress to convert ARM over which will replace the
platform MSI train-wreck. The cleanup of VFIO, NTB and other creative
"solutions" are in the works as well.

- When 3170 terminal emulator is connected to the 3215 console driver
the boot time could be very long due to limited buffer space or
missing operator input. Add con3215_drop command line parameter and
con3215_drop sysfs attribute file to instruct the kernel drop console
data when such conditions are met
- Fix white space errors in 3215 console driver
- Move enum paiext_mode definition to a header file and rename it to
paievt_mode to indicate this is now used for several events. Rename
PAI_MODE_COUNTER to PAI_MODE_COUNTING to make consistent with
PAI_MODE_SAMPLING
- Simplify the logic of PMU pai_crypto mapped buffer reference counter
and make it consistent with PMU pai_ext
- Rename PMU pai_crypto mapped buffer structure member users to
active_events to make it consistent with PMU pai_ext
- Enable HUGETLB_PAGE_OPTIMIZE_VMEMMAP configuration option. This
results in saving of 12K per 1M hugetlb page (~1.2%) and 32764K per
2G hugetlb page (~1.6%)
- Use generic serial.h, bugs.h, shmparam.h and vga.h header files and
scrap s390-specific versions
- The generic percpu setup code does not expect the s390-like
implementation and emits a warning. To get rid of that warning and
provide sane CPU-to-node and CPU-to-CPU distance mappings implementat
a minimal version of setup_per_cpu_areas()
- Use kstrtobool() instead of strtobool() for re-IPL sysfs device
attributes
- Avoid unnecessary lookup of a pointer to MSI descriptor when setting
IRQ affinity for a PCI device
- Get rid of "an incompatible function type cast" warning by changing
debug_sprintf_format_fn() function prototype so it matches the
debug_format_proc_t function type
- Remove unused info_blk_hdr__pcpus() and get_page_state() functions
- Get rid of clang "unused unused insn cache ops function" warning by
moving s390_insn definition to a private header
- Get rid of clang "unused function" warning by making function
raw3270_state_final() only available if CONFIG_TN3270_CONSOLE is
enabled
- Use kstrobool() to parse sclp_con_drop parameter to make it identical
to the con3215_drop parameter and allow passing values like "yes" and
"true"
- Use sysfs_emit() for all SCLP sysfs show functions, which is the
current standard way to generate output strings
- Make SCLP con_drop sysfs attribute also writable and allow to change
its value during runtime. This makes SCLP console drop handling
consistent with the 3215 device driver
- Virtual and physical addresses are indentical on s390. However, there
is still a confusion when pointers are directly casted to physical
addresses or vice versa. Use correct address converters
virt_to_phys() and phys_to_virt() for s390 channel IO drivers
- Support for power managemant has been removed from s390 since quite
some time. Remove unused power managemant code from the appldata
device driver
- Allow memory tools like KASAN see memory accesses from the checksum
code. Switch to GENERIC_CSUM if KASAN is enabled, just like x86 does
- Add support of ECKD DASDs disks so it could be used as boot and dump
devices
- Follow checkpatch recommendations and use octal values instead of
S_IRUGO and S_IWUSR for dump device attributes in sysfs
- Changes to vx-insn.h do not cause a recompile of C files that use
asm(".include \"asm/vx-insn.h\"\n") magic to access vector
instruction macros from inline assemblies. Add wrapper include header
file to avoid this problem
- Use vector instruction macros instead of byte patterns to increase
register validation routine readability
- The current machine check register validation handling does not take
into account various scenarios and might lead to killing a wrong user
process or potentially ignore corrupted FPU registers. Simplify logic
of the machine check handler and stop the whole machine if the
previous context was kerenel mode. If the previous context was user
mode, kill the current task
- Introduce sclp_emergency_printk() function which can be used to emit
a message in emergency cases. It is supposed to be used in cases
where regular console device drivers may not work anymore, e.g.
unrecoverable machine checks
Keep the early Service-Call Control Block so it can also be used
after initdata has been freed to allow sclp_emergency_printk()
implementation
- In case a system will be stopped because of an unrecoverable machine
check error print the machine check interruption code to give a hint
of what went wrong
- Move storage error checking from the assembly entry code to C in
order to simplify machine check handling. Enter the handler with DAT
turned on, which simplifies the entry code even more
- The machine check extended save areas are allocated using a private
"nmi_save_areas" slab cache which guarantees a required power-of-two

Pull ARM SoC DT updates from Arnd Bergmann:
"The devicetree changes contain exactly 1000 non-merge changesets,
including a number of new arm64 SoC variants from Qualcomm and Apple,
as well as the Renesas r9a07g043f/u chip in both arm64 and riscv
variants.
While we have occasionally merged support for non-arm SoCs in the
past, this is now the normal path for riscv devicetree files.
The most notable changes, by SoC platform, are:
- The Apple T6000 (M1 Pro), T6001 (M1 Max) and T6002 (M1 Ultra) chips
now have initial support. This is particularly nice as I am typing
this on a T6002 Mac Studio with only a small number of driver
patches.
- Qualcomm MSM8996 Pro (Snapdragon 821), SM6115 (Snapdragon 662),
SM4250 (Snapdragon 460), SM6375 (Snapdragon 695), SDM670
(Snapdragon 670), MSM8976 (Snapdragon 652) and MSM8956 (Snapdragon
650) are all mobile phone chips that are closely related to others
we already support.
Adding those helps support more phones and we add several models
from Sony (Xperia 10 IV, 5 IV, X, and X compact), OnePlus (One, 3,
3T, and Nord N100), Xiaomi (Poco F1, Mi6), Huawei (Watch) and
Google (Pixel 3a).
There are also new variants of the Herobrine and Trogdor chromebook
motherboards. SA8540P is an automotive SoC used in the Qdrive-3
development platform
- Rockchips gains no new SoC variants, but a lot of new boards: three
mobile gaming systems based on RK3326 Odroid-Go/rg351 family, two
more Anbernic gaming systems based on RK3566 and a number of other
RK356x based single-board computers.
- Renesas RZ/G2UL (r9a07g043) was already supported for arm64, but as
the newly added RZ/Five is based on the same design, this now gets
reorganized in order to share most of the dts description between
the two and add the RZ/Five SMARC EVK board support.
Aside from that, there are the usual changes all over the tree:
- New boards on other platforms contain two ASpeed BMC users, two
Broadcom based Wifi routers, Zyxel NSA310S NAS, the i.MX6 based
Kobo Aura2 ebook reader, two i.MX8 based development boards, two
Uniphier Pro5 development boards, the STM32MP1 testbench board from
DHCOR, the TI K3 based BeagleBone AI-64 board, and the Mediatek
Helio X10 based Sony Xperia M5 phone.
- The Starfive JH7100 source gets reorganized in order to support the
VisionFive V1 board.
- Minor updates and cleanups for Intel SoCFPGA, Marvell PXA168, TI,
ST, NXP, Apple, Broadcom, Juno, Marvell MVEBU, at91, nuvoton,
Tegra, Mediatek, Renesas, Hisilicon, Allwinner, Samsung, ux500,
spear, ... The treewide cleanups now have a lot of fixes for cache
nodes and other binding violoations.
- Somewhat larger sets of reworks for NVIDIA Tegra, Qualcomm and
Renesas platforms, adding a lot more on-chip device support
- A rework of the way that DTB overlays are built"

Pull arm64 updates from Will Deacon:
"The highlights this time are support for dynamically enabling and
disabling Clang's Shadow Call Stack at boot and a long-awaited
optimisation to the way in which we handle the SVE register state on
system call entry to avoid taking unnecessary traps from userspace.
Summary:
ACPI:
- Enable FPDT support for boot-time profiling
- Fix CPU PMU probing to work better with PREEMPT_RT
- Update SMMUv3 MSI DeviceID parsing to latest IORT spec
- APMT support for probing Arm CoreSight PMU devices
CPU features:
- Advertise new SVE instructions (v2.1)
- Advertise range prefetch instruction
- Advertise CSSC ("Common Short Sequence Compression") scalar
instructions, adding things like min, max, abs, popcount
- Enable DIT (Data Independent Timing) when running in the kernel
- More conversion of system register fields over to the generated
header
CPU misfeatures:
- Workaround for Cortex-A715 erratum #2645198
Dynamic SCS:
- Support for dynamic shadow call stacks to allow switching at
runtime between Clang's SCS implementation and the CPU's pointer
authentication feature when it is supported (complete with scary
DWARF parser!)
Tracing and debug:
- Remove static ftrace in favour of, err, dynamic ftrace!
- Seperate 'struct ftrace_regs' from 'struct pt_regs' in core ftrace
and existing arch code
- Introduce and implement FTRACE_WITH_ARGS on arm64 to replace the
old FTRACE_WITH_REGS
- Extend 'crashkernel=' parameter with default value and fallback to
placement above 4G physical if initial (low) allocation fails
SVE:
- Optimisation to avoid disabling SVE unconditionally on syscall
entry and just zeroing the non-shared state on return instead
Exceptions:
- Rework of undefined instruction handling to avoid serialisation on
global lock (this includes emulation of user accesses to the ID
registers)
Perf and PMU:
- Support for TLP filters in Hisilicon's PCIe PMU device
- Support for the DDR PMU present in Amlogic Meson G12 SoCs
- Support for the terribly-named "CoreSight PMU" architecture from
Arm (and Nvidia's implementation of said architecture)
Misc:
- Tighten up our boot protocol for systems with memory above 52 bits
physical
- Const-ify static keys to satisty jump label asm constraints
- Trivial FFA driver cleanups in preparation for v1.1 support
- Export the kernel_neon_* APIs as GPL symbols
- Harden our instruction generation routines against instrumentation
- A bunch of robustness improvements to our arch-specific selftests
- Minor cleanups and fixes all over (kbuild, kprobes, kfence, PMU, ...)"

git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab
Pull slab updates from Vlastimil Babka:
- SLOB deprecation and SLUB_TINY
The SLOB allocator adds maintenance burden and stands in the way of
API improvements [1]. Deprecate it by renaming the config option (to
make users notice) to CONFIG_SLOB_DEPRECATED with updated help text.
SLUB should be used instead as SLAB will be the next on the removal
list.
Based on reports from a riscv k210 board with 8MB RAM, add a
CONFIG_SLUB_TINY option to minimize SLUB's memory usage at the
expense of scalability. This has resolved the k210 regression [2] so
in case there are no others (that wouldn't be resolvable by further
tweaks to SLUB_TINY) plan is to remove SLOB in a few cycles.
Existing defconfigs with CONFIG_SLOB are converted to
CONFIG_SLUB_TINY.
- kmalloc() slub_debug redzone improvements
A series from Feng Tang that builds on the tracking or requested size
for kmalloc() allocations (for caches with debugging enabled) added
in 6.1, to make redzone checks consider the requested size and not
the rounded up one, in order to catch more subtle buffer overruns.
Includes new slub_kunit test.
- struct slab fields reordering to accomodate larger rcu_head
RCU folks would like to grow rcu_head with debugging options, which
breaks current struct slab layout's assumptions, so reorganize it to
make this possible.
- Miscellaneous improvements/fixes:
- __alloc_size checking compiler workaround (Kees Cook)
- Optimize and cleanup SLUB's sysfs init (Rasmus Villemoes)
- Make SLAB compatible with PROVE_RAW_LOCK_NESTING (Jiri Kosina)
- Correct SLUB's percpu allocation estimates (Baoquan He)

Pull printk updates from Petr Mladek:
- Add NMI-safe SRCU reader API. It uses atomic_inc() instead of
this_cpu_inc() on strong load-store architectures.
- Introduce new console_list_lock to synchronize a manipulation of the
list of registered consoles and their flags.
This is a first step in removing the big-kernel-lock-like behavior of
console_lock(). This semaphore still serializes console->write()
calbacks against:
- each other. It primary prevents potential races between early
and proper console drivers using the same device.
- suspend()/resume() callbacks and init() operations in some
drivers.
- various other operations in the tty/vt and framebufer
susbsystems. It is likely that console_lock() serializes even
operations that are not directly conflicting with the
console->write() callbacks here. This is the most complicated
big-kernel-lock aspect of the console_lock() that will be hard
to untangle.
- Introduce new console_srcu lock that is used to safely iterate and
access the registered console drivers under SRCU read lock.
This is a prerequisite for introducing atomic console drivers and
console kthreads. It will reduce the complexity of serialization
against normal consoles and console_lock(). Also it should remove the
risk of deadlock during critical situations, like Oops or panic, when
only atomic consoles are registered.
- Check whether the console is registered instead of enabled on many
locations. It was a historical leftover.
- Cleanly force a preferred console in xenfb code instead of a dirty
hack.
- A lot of code and comment clean ups and improvements.

Pull file locking updates from Jeff Layton:
"The main change here is to add the new locks_inode_context helper, and
convert all of the places that dereference inode->i_flctx directly to
use that instead.
There is a new helper to indicate whether any locks are held on an
inode. This is mostly for Ceph but may be usable elsewhere too.
Andi Kleen requested that we print the PID when the LOCK_MAND warning
fires, to help track down applications trying to use it.
Finally, we added some new warnings to some of the file locking
functions that fire when the ->fl_file and filp arguments differ. This
helped us find some long-standing bugs in lockd. Patches for those are
in Chuck Lever's tree and should be in his v6.2 PR. After that patch,
people using NFSv2/v3 locking may see some warnings fire until those
go in.
Happy Holidays!"

Pull unsigned-char conversion from Jason Donenfeld:
"Enable -funsigned-char and fix code affected by that flag.
During the 6.1 cycle, several patches already made it into the tree,
which were for code that was already broken on at least one
architecture, where the naked char had a different sign than the code
author anticipated, or were part of some bug fix for an existing bug
that this initiative unearthed.
These 6.1-era fixes are:
648060902aa3 ("MIPS: pic32: treat port as signed integer")
5c26159c97b3 ("ipvs: use explicitly signed chars")
e6cb8769452e ("wifi: airo: do not assign -1 to unsigned char")
937ec9f7d5f2 ("staging: rtl8192e: remove bogus ssid character sign test")
677047383296 ("misc: sgi-gru: use explicitly signed char")
50895a55bcfd ("ALSA: rme9652: use explicitly signed char")
ee03c0f200eb ("ALSA: au88x0: use explicitly signed char")
835bed1b8395 ("fbdev: sisfb: use explicitly signed char")
50f19697dd76 ("parisc: Use signed char for hardware path in pdc.h")
66063033f77e ("wifi: rt2x00: use explicitly signed or unsigned types")
Regarding patches in this pull:
- There is one patch in this pull that should have made it to you
during 6.1 ("media: stv0288: use explicitly signed char"), but the
maintainer was MIA during the cycle, so it's in here instead.
- Two patches fix single architecture code affected by unsigned char
("perf/x86: Make struct p4_event_bind::cntr signed array" and
"sparc: sbus: treat CPU index as integer"), while one patch fixes
an unused typedef, in case it's ever used in the future ("media:
atomisp: make hive_int8 explictly signed").
- Finally, there's the change to actually enable -funsigned-char
("kbuild: treat char as always unsigned") and then the removal of
some no longer useful !__CHAR_UNSIGNED__ selftest code ("lib:
assume char is unsigned").
The various fixes were found with a combination of diffing objdump
output, a large variety of Coccinelle scripts, and plain old grep. In
the end, things didn't seem as bad as I feared they would. But of
course, it's also possible I missed things.
However, this has been in linux-next for basically an entire cycle
now, so I'm not overly worried. I've also been daily driving this on
my laptop for all of 6.1. Still, this series, and the ones sent for
6.1 don't total in quantity to what I thought it'd be, so I will be on
the lookout for breakage.
We could receive a few reports that are quickly fixable. Hopefully we
won't receive a barrage of reports that would result in a revert. And
just maybe we won't receive any reports at all and nobody will even
notice. Knock on wood"
