i2c: nomadik: fix BRCR computation
Current BRCR computation is:
brcr = floor(i2cclk / (clkfreq * div))
With brcr: "baud rate counter", an internal clock divider,
and i2cclk: input clock rate (24MHz, 38.4MHz or 48MHz),
and clkfreq: desired bus rate,
and div: speed-mode dependent divider (2 for standard, 3 otherwise).
Assume i2cclk=48MHz, clkfreq=3.4MHz, div=3,
then brcr = floor(48MHz / (3.4MHz * 3)) = 4
and resulting bus rate = 48MHz / (4 * 3) = 4MHz
Assume i2cclk=38.4MHz, clkfreq=1.0MHz, div=3,
then brcr = floor(38.4MHz / (1.0MHz * 3)) = 12
and resulting bus rate = 38.4MHz / (12 * 3) = 1066kHz
The current computation means we always pick the smallest divider that
gives a bus rate above target. We should instead pick the largest
divider that gives a bus rate below target, using:
brcr = floor(i2cclk / (clkfreq * div)) + 1
If we redo the above examples:
Assume i2cclk=48MHz, clkfreq=3.4MHz, div=3,
then brcr = floor(48MHz / (3.4MHz * 3)) + 1 = 5
and resulting bus rate = 48MHz / (5 * 3) = 3.2MHz
Assume i2cclk=38.4MHz, clkfreq=1.0MHz, div=3,
then brcr = floor(38.4MHz / (1.0MHz * 3)) + 1 = 13
and resulting bus rate = 38.4MHz / (13 * 3) = 985kHz
In kernel C code, floor(x) is DIV_ROUND_DOWN() and,
floor(x)+1 is DIV_ROUND_UP().
This is much less of an issue with slower bus rates (ie those currently
supported), because the gap from one divider to the next is much
smaller. It however keeps us from always using bus rates superior to
the target.
This fix is required for later on supporting faster bus rates:
I2C_FREQ_MODE_FAST_PLUS (1MHz) and I2C_FREQ_MODE_HIGH_SPEED (3.4MHz).

i2c: nomadik: support Mobileye EyeQ6H I2C controller
Add EyeQ6H support to the nmk-i2c AMBA driver. It shares the same quirk
as EyeQ5: the memory bus only supports 32-bit accesses. Avoid writeb()
and readb() by reusing the same `priv->has_32b_bus` flag.
It does NOT need to write speed-mode specific value into a register;
therefore it does not depend on the mobileye,olb DT property.

Pull kvm updates from Paolo Bonzini:
"The biggest change here is eliminating the awful idea that KVM had of
essentially guessing which pfns are refcounted pages.
The reason to do so was that KVM needs to map both non-refcounted
pages (for example BARs of VFIO devices) and VM_PFNMAP/VM_MIXMEDMAP
VMAs that contain refcounted pages.
However, the result was security issues in the past, and more recently
the inability to map VM_IO and VM_PFNMAP memory that _is_ backed by
struct page but is not refcounted. In particular this broke virtio-gpu
blob resources (which directly map host graphics buffers into the
guest as "vram" for the virtio-gpu device) with the amdgpu driver,
because amdgpu allocates non-compound higher order pages and the tail
pages could not be mapped into KVM.
This requires adjusting all uses of struct page in the
per-architecture code, to always work on the pfn whenever possible.
The large series that did this, from David Stevens and Sean
Christopherson, also cleaned up substantially the set of functions
that provided arch code with the pfn for a host virtual addresses.
The previous maze of twisty little passages, all different, is
replaced by five functions (__gfn_to_page, __kvm_faultin_pfn, the
non-__ versions of these two, and kvm_prefetch_pages) saving almost
200 lines of code.
ARM:
- Support for stage-1 permission indirection (FEAT_S1PIE) and
permission overlays (FEAT_S1POE), including nested virt + the
emulated page table walker
- Introduce PSCI SYSTEM_OFF2 support to KVM + client driver. This
call was introduced in PSCIv1.3 as a mechanism to request
hibernation, similar to the S4 state in ACPI
- Explicitly trap + hide FEAT_MPAM (QoS controls) from KVM guests. As
part of it, introduce trivial initialization of the host's MPAM
context so KVM can use the corresponding traps
- PMU support under nested virtualization, honoring the guest
hypervisor's trap configuration and event filtering when running a
nested guest
- Fixes to vgic ITS serialization where stale device/interrupt table
entries are not zeroed when the mapping is invalidated by the VM
- Avoid emulated MMIO completion if userspace has requested
synchronous external abort injection
- Various fixes and cleanups affecting pKVM, vCPU initialization, and
selftests
LoongArch:
- Add iocsr and mmio bus simulation in kernel.
- Add in-kernel interrupt controller emulation.
- Add support for virtualization extensions to the eiointc irqchip.
PPC:
- Drop lingering and utterly obsolete references to PPC970 KVM, which
was removed 10 years ago.
- Fix incorrect documentation references to non-existing ioctls
RISC-V:
- Accelerate KVM RISC-V when running as a guest
- Perf support to collect KVM guest statistics from host side
s390:
- New selftests: more ucontrol selftests and CPU model sanity checks
- Support for the gen17 CPU model
- List registers supported by KVM_GET/SET_ONE_REG in the
documentation
x86:
- Cleanup KVM's handling of Accessed and Dirty bits to dedup code,
improve documentation, harden against unexpected changes.
Even if the hardware A/D tracking is disabled, it is possible to
use the hardware-defined A/D bits to track if a PFN is Accessed
and/or Dirty, and that removes a lot of special cases.
- Elide TLB flushes when aging secondary PTEs, as has been done in
x86's primary MMU for over 10 years.
- Recover huge pages in-place in the TDP MMU when dirty page logging
is toggled off, instead of zapping them and waiting until the page
is re-accessed to create a huge mapping. This reduces vCPU jitter.
- Batch TLB flushes when dirty page logging is toggled off. This
reduces the time it takes to disable dirty logging by ~3x.
- Remove the shrinker that was (poorly) attempting to reclaim shadow
page tables in low-memory situations.
- Clean up and optimize KVM's handling of writes to
MSR_IA32_APICBASE.
- Advertise CPUIDs for new instructions in Clearwater Forest
- Quirk KVM's misguided behavior of initialized certain feature MSRs
to their maximum supported feature set, which can result in KVM
creating invalid vCPU state. E.g. initializing PERF_CAPABILITIES to
a non-zero value results in the vCPU having invalid state if
userspace hides PDCM from the guest, which in turn can lead to
save/restore failures.
- Fix KVM's handling of non-canonical checks for vCPUs that support
LA57 to better follow the "architecture", in quotes because the
actual behavior is poorly documented. E.g. most MSR writes and
descriptor table loads ignore CR4.LA57 and operate purely on
whether the CPU supports LA57.
- Bypass the register cache when querying CPL from kvm_sched_out(),
as filling the cache from IRQ context is generally unsafe; harden
the cache accessors to try to prevent similar issues from occuring
in the future. The issue that triggered this change was already
fixed in 6.12, but was still kinda latent.
- Advertise AMD_IBPB_RET to userspace, and fix a related bug where
KVM over-advertises SPEC_CTRL when trying to support cross-vendor
VMs.
- Minor cleanups
- Switch hugepage recovery thread to use vhost_task.
These kthreads can consume significant amounts of CPU time on
behalf of a VM or in response to how the VM behaves (for example
how it accesses its memory); therefore KVM tried to place the
thread in the VM's cgroups and charge the CPU time consumed by that
work to the VM's container.
However the kthreads did not process SIGSTOP/SIGCONT, and therefore
cgroups which had KVM instances inside could not complete freezing.
Fix this by replacing the kthread with a PF_USER_WORKER thread, via
the vhost_task abstraction. Another 100+ lines removed, with
generally better behavior too like having these threads properly
parented in the process tree.
- Revert a workaround for an old CPU erratum (Nehalem/Westmere) that
didn't really work; there was really nothing to work around anyway:
the broken patch was meant to fix nested virtualization, but the
PERF_GLOBAL_CTRL MSR is virtualized and therefore unaffected by the
erratum.
- Fix 6.12 regression where CONFIG_KVM will be built as a module even
if asked to be builtin, as long as neither KVM_INTEL nor KVM_AMD is
'y'.
x86 selftests:
- x86 selftests can now use AVX.
Documentation:
- Use rST internal links
- Reorganize the introduction to the API document
Generic:
- Protect vcpu->pid accesses outside of vcpu->mutex with a rwlock
instead of RCU, so that running a vCPU on a different task doesn't
encounter long due to having to wait for all CPUs become quiescent.
In general both reads and writes are rare, but userspace that
supports confidential computing is introducing the use of "helper"
vCPUs that may jump from one host processor to another. Those will
be very happy to trigger a synchronize_rcu(), and the effect on
performance is quite the disaster"

SPI NOR flashes may swap the bytes on a 16-bit boundary when

propagated through SPI MEM to the SPI controllers so that the
controllers swap the bytes back at runtime. This avoids breaking
the boot sequence because of the endianness problems that appear
when the bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with
byte swap support. Along with the SPI MEM byte swap support we
queue a patch for the SPI MXIC controller that swaps the bytes back

Pull tracing updates from Steven Rostedt:
- Addition of faultable tracepoints
There's a tracepoint attached to both a system call entry and exit.
This location is known to allow page faults. The tracepoints are
called under an rcu_read_lock() which does not allow faults that can
sleep. This limits the ability of tracepoint handlers to page fault
in user space system call parameters. Now these tracepoints have been
made "faultable", allowing the callbacks to fault in user space
parameters and record them.
Note, only the infrastructure has been implemented. The consumers
(perf, ftrace, BPF) now need to have their code modified to allow
faults.
- Fix up of BPF code for the tracepoint faultable logic
- Update tracepoints to use the new static branch API
- Remove trace_*_rcuidle() variants and the SRCU protection they used
- Remove unused TRACE_EVENT_FL_FILTERED logic
- Replace strncpy() with strscpy() and memcpy()
- Use replace per_cpu_ptr(smp_processor_id()) with this_cpu_ptr()
- Fix perf events to not duplicate samples when tracing is enabled
- Replace atomic64_add_return(1, counter) with
atomic64_inc_return(counter)
- Make stack trace buffer 4K instead of PAGE_SIZE
- Remove TRACE_FLAG_IRQS_NOSUPPORT flag as it was never used
- Get the true return address for function tracer when function graph
tracer is also running.
When function_graph trace is running along with function tracer, the
parent function of the function tracer sometimes is
"return_to_handler", which is the function graph trampoline to record
the exit of the function. Use existing logic that calls into the
fgraph infrastructure to find the real return address.
- Remove (un)regfunc pointers out of tracepoint structure
- Added last minute bug fix for setting pending modules in stack
function filter.

make sure that the ring buffer has not been corrupted. Commit c2274b908db0 ("ring-buffer: Fix a race between readers and resize
checks") fixed a race with the check pages and simultaneous resizes
to the ring buffer by adding a raw_spin_lock_irqsave() around the
check operation. Although this was a simple fix, it would hold
interrupts disabled for non determinative amount of time. This could
harm PREEMPT_RT operations.
Instead, modify the logic by adding a counter when the buffer is
modified and to release the raw_spin_lock() at each iteration. It
checks the counter under the lock to see if a modification happened
during the loop, and if it did, it would restart the loop up to 3
times. After 3 times, it will simply exit the check, as it is
unlikely that would ever happen as buffer resizes are rare
occurrences.

"These essentially refine some interactions between TDX guests and
VMMs.
The first leverages a new TDX module feature to runtime disable the
ability for a VM to inject #VE exceptions. Before this feature, there
was only a static on/off switch and the guest had to panic if it was
configured in a bad state.
The second lets the guest opt in to be able to access the topology
CPUID leaves. Before this, accesses to those leaves would #VE.
For both of these, it would have been nicest to just change the
default behavior, but some pesky "other" OSes evidently need to retain
the legacy behavior.

- Add new infrastructure for reading TDX metadata
- Use the newly-available metadata to:
- Disable potentially nasty #VE exceptions

The PPC64 specific MMIO setup open codes DT address functions rather
than using standard address parsing functions. The open-coded version
fails to handle any address translation and is not endian safe.
I haven't found any evidence of what platform used this. The only thing
that turned up was a PPC405 platform, but that is 32-bit and PPC405
support is being removed as well. CONFIG_TCG_ATMEL is not enabled for
any powerpc config and never was. The support was added in 2005 and
hasn't been touched since.
Rather than try to modernize and fix this code, just remove it.

Remove tpm_get_timeouts, tpm2_get_cc_attrs_tbl, and tpm2_sessions_init
calls from it since these will all be called in tpm2_auto_startup and
tpm1_auto_startup.
The exporting of the tpm2_session_init symbol was only necessary while the
ibmvtpm driver was calling this function. Since this is not the case
anymore, remove this symbol from being exported.
What is new for the ibmvtpm driver is that now tpm2_do_selftest and
tpm1_do_selftest will be called that send commands to the TPM to perform
or continue its selftest. However, the firmware should already have sent
these commands so that the TPM will not do much work at this time.

Pull iommufd updates from Jason Gunthorpe:
"Several new features and uAPI for iommufd:
- IOMMU_IOAS_MAP_FILE allows passing in a file descriptor as the
backing memory for an iommu mapping. To date VFIO/iommufd have used
VMA's and pin_user_pages(), this now allows using memfds and
memfd_pin_folios(). Notably this creates a pure folio path from the
memfd to the iommu page table where memory is never broken down to
PAGE_SIZE.
- IOMMU_IOAS_CHANGE_PROCESS moves the pinned page accounting between
two processes. Combined with the above this allows iommufd to
support a VMM re-start using exec() where something like qemu would
exec() a new version of itself and fd pass the memfds/iommufd/etc
to the new process. The memfd allows DMA access to the memory to
continue while the new process is getting setup, and the
CHANGE_PROCESS updates all the accounting.
- Support for fault reporting to userspace on non-PRI HW, such as ARM
stall-mode embedded devices.
- IOMMU_VIOMMU_ALLOC introduces the concept of a HW/driver backed
virtual iommu. This will be used by VMMs to access hardware
features that are contained with in a VM. The first use is to
inform the kernel of the virtual SID to physical SID mapping when
issuing SID based invalidation on ARM. Further uses will tie HW
features that are directly accessed by the VM, such as invalidation
queue assignment and others.
- IOMMU_VDEVICE_ALLOC informs the kernel about the mapping of virtual
device to physical device within a VIOMMU. Minimially this is used
to translate VM issued cache invalidation commands from virtual to
physical device IDs.
- Enhancements to IOMMU_HWPT_INVALIDATE and IOMMU_HWPT_ALLOC to work
with the VIOMMU
- ARM SMMuv3 support for nested translation. Using the VIOMMU and
VDEVICE the driver can model this HW's behavior for nested
translation. This includes a shared branch from Will"

smb: prevent use-after-free due to open_cached_dir error paths
If open_cached_dir() encounters an error parsing the lease from the
server, the error handling may race with receiving a lease break,
resulting in open_cached_dir() freeing the cfid while the queued work is
pending.
Update open_cached_dir() to drop refs rather than directly freeing the
cfid.
Have cached_dir_lease_break(), cfids_laundromat_worker(), and
invalidate_all_cached_dirs() clear has_lease immediately while still
holding cfids->cfid_list_lock, and then use this to also simplify the
reference counting in cfids_laundromat_worker() and
invalidate_all_cached_dirs().
Fixes this KASAN splat (which manually injects an error and lease break
in open_cached_dir()):

smb: Don't leak cfid when reconnect races with open_cached_dir
open_cached_dir() may either race with the tcon reconnection even before
compound_send_recv() or directly trigger a reconnection via
SMB2_open_init() or SMB_query_info_init().
The reconnection process invokes invalidate_all_cached_dirs() via
cifs_mark_open_files_invalid(), which removes all cfids from the
cfids->entries list but doesn't drop a ref if has_lease isn't true. This
results in the currently-being-constructed cfid not being on the list,
but still having a refcount of 2. It leaks if returned from
open_cached_dir().
Fix this by setting cfid->has_lease when the ref is actually taken; the
cfid will not be used by other threads until it has a valid time.

cifs: Recognize SFU char/block devices created by Windows NFS server on Windows Server <<2012
Windows NFS server versions on Windows Server older than 2012 release use
for storing char and block devices modified SFU format, not compatible with
the original SFU. Windows NFS server on Windows Server 2012 and new
versions use different format (reparse points), not related to SFU-style.
SFU / SUA / Interix subsystem stores the major and major numbers as pair of
64-bit integer, but Windows NFS server stores as pair of 32-bit integers.
Which makes char and block devices between Windows NFS server <<2012 and
Windows SFU/SUA/Interix subsytem incompatible.
So improve Linux SMB client.
When SFU mode is enabled (mount option -o sfu is specified) then recognize

CIFS: New mount option for cifs.upcall namespace resolution
In the current implementation, the SMB filesystem on a mount point can
trigger upcalls from the kernel to the userspace to enable certain
functionalities like spnego, dns_resolution, amongst others. These upcalls
usually either happen in the context of the mount or in the context of an
application/user. The upcall handler for cifs, cifs.upcall already has
existing code which switches the namespaces to the caller's namespace
before handling the upcall. This behaviour is expected for scenarios like
multiuser mounts, but might not cover all single user scenario with
services such as Kubernetes, where the mount can happen from different
locations such as on the host, from an app container, or a driver pod
which does the mount on behalf of a different pod.
This patch introduces a new mount option called upcall_target, to
customise the upcall behaviour. upcall_target can take 'mount' and 'app'
as possible values. This aids use cases like Kubernetes where the mount
happens on behalf of the application in another container altogether.
Having this new mount option allows the mount command to specify where the
upcall should happen: 'mount' for resolving the upcall to the host
namespace, and 'app' for resolving the upcall to the ns of the calling
thread. This will enable both the scenarios where the Kerberos credentials
can be found on the application namespace or the host namespace to which
just the mount operation is "delegated".

Pull networking updates from Paolo Abeni:
"The most significant set of changes is the per netns RTNL. The new
behavior is disabled by default, regression risk should be contained.
Notably the new config knob PTP_1588_CLOCK_VMCLOCK will inherit its
default value from PTP_1588_CLOCK_KVM, as the first is intended to be
a more reliable replacement for the latter.
Core:
- Started a very large, in-progress, effort to make the RTNL lock
scope per network-namespace, thus reducing the lock contention
significantly in the containerized use-case, comprising:
- RCU-ified some relevant slices of the FIB control path
- introduce basic per netns locking helpers
- namespacified the IPv4 address hash table
- remove rtnl_register{,_module}() in favour of
rtnl_register_many()
- refactor rtnl_{new,del,set}link() moving as much validation as
possible out of RTNL lock
- convert all phonet doit() and dumpit() handlers to RCU
- convert IPv4 addresses manipulation to per-netns RTNL
- convert virtual interface creation to per-netns RTNL
the per-netns lock infrastructure is guarded by the
CONFIG_DEBUG_NET_SMALL_RTNL knob, disabled by default ad interim.
- Introduce NAPI suspension, to efficiently switching between busy
polling (NAPI processing suspended) and normal processing.
- Migrate the IPv4 routing input, output and control path from direct
ToS usage to DSCP macros. This is a work in progress to make ECN
handling consistent and reliable.
- Add drop reasons support to the IPv4 rotue input path, allowing
better introspection in case of packets drop.
- Make FIB seqnum lockless, dropping RTNL protection for read access.
- Make inet{,v6} addresses hashing less predicable.
- Allow providing timestamp OPT_ID via cmsg, to correlate TX packets
and timestamps
Things we sprinkled into general kernel code:
- Add small file operations for debugfs, to reduce the struct ops
size.
- Refactoring and optimization for the implementation of page_frag
API, This is a preparatory work to consolidate the page_frag
implementation.
Netfilter:
- Optimize set element transactions to reduce memory consumption
- Extended netlink error reporting for attribute parser failure.
- Make legacy xtables configs user selectable, giving users the
option to configure iptables without enabling any other config.
- Address a lot of false-positive RCU issues, pointed by recent CI
improvements.
BPF:
- Put xsk sockets on a struct diet and add various cleanups. Overall,
this helps to bump performance by 12% for some workloads.
- Extend BPF selftests to increase coverage of XDP features in
combination with BPF cpumap.
- Optimize and homogenize bpf_csum_diff helper for all archs and also
add a batch of new BPF selftests for it.
- Extend netkit with an option to delegate skb->{mark,priority}
scrubbing to its BPF program.
- Make the bpf_get_netns_cookie() helper available also to tc(x) BPF
programs.
- Add a fastpath for some TCP timers that usually expires after
close, the socket lock contention.
- Add inbound and outbound xfrm state caches to speed up state
lookups.
- Avoid sending MPTCP advertisements on stale subflows, reducing
risks on loosing them.
- Make neighbours table flushing more scalable, maintaining per
device neigh lists.
Driver API:
- Introduce a unified interface to configure transmission H/W
shaping, and expose it to user-space via generic-netlink.
- Add support for per-NAPI config via netlink. This makes napi
configuration persistent across queues removal and re-creation.
Requires driver updates, currently supported drivers are:
nVidia/Mellanox mlx4 and mlx5, Broadcom brcm and Intel ice.
- Add ethtool support for writing SFP / PHY firmware blocks.
- Track RSS context allocation from ethtool core.
- Implement support for mirroring to DSA CPU port, via TC mirror
offload.
- Consolidate FDB updates notification, to avoid duplicates on
device-specific entries.
- Expose DPLL clock quality level to the user-space.
- Support master-slave PHY config via device tree.
Tests and tooling:
- forwarding: introduce deferred commands, to simplify the cleanup
phase
Drivers:
- Updated several drivers - Amazon vNic, Google vNic, Microsoft vNic,
Intel e1000e and Broadcom Tigon3 - to use netdev-genl to link the
IRQs and queues to NAPI IDs, allowing busy polling and better
introspection.

extensions, allowing more flexible use of the shared memory area
and new DT binding properties for configurability.
- Mediatek SoC drivers gain support for power managment on the MT8188
SoC and a new driver for DVFS.
- The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
and a few bugfixes
- The Hisilicon Kunpeng HCCS driver gains support for configuring
lanes through sysfs
Finally, there are cleanups and minor fixes for drivers/{soc, bus,
memory}, including changing back the .remove_new callback to .remove,
as well as a few other updates for freescale (powerpc) soc drivers,
NXP i.MX soc drivers, cznic turris platform driver, memory controller

Pull SoC devicetree updates from Arnd Bergmann:
"This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device
driver and platform code has already made it in. This is likely the
last ARMv5 (!) platform to ever get added, updating the 20+ year
old at91/sam9 platform with DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number
of A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in
older Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely
related to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end
laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and
Tablet chips, still using the older ARMv8.0 cores from
RK3328/RK3399 but with a newer process and other improvements from
the RK35xx (otherwise ARMv8.2) chips. RK3566T and RK3399-S are also
added, these are just lower-cost versions of their normal
counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly
added chips above, notably all the Apple phones and tablets. The other
new machines include nine industrial/embedded boards with NXP i.MX6 or
i.MX8 SoCs, eight for Rockchips RK35XX and one or two each for
Rockchips RV1109, RK3308, Allwinner A33, Tegra 234, Qualcomm
qcs9100/sc8280xp/x1e80100, TI AM625 and Starfive JH7110.
As usual there are also many newly added features in existing boards
as well as cleanups and minor bugfixes"

- constify the sysfs class struct
- use lock guards in GPIO sysfs code
- update GPIO uAPI internal flags all at once atomically for
consistency with other places
- modify the behavior of the sysfs interface by no longer exporting
lines that are named inside the driver code or board files with the
sysfs links bearing the line names as this has for many years been
largely unused due to the prevalence of DT, ACPI and firmware nodes
over board files and made the API inconsistent
- for GPIO interrupt providers: free irqs that are still requested by
users when removing the chip
GPIO uAPI:
- notify user-space about changes to GPIO lines' state (requested,
released, reconfigured) triggered from the kernel as well (until
now we'd only do this for changes triggered from user-space)
- to that end: modify the internal workings of the notification
mechanism by switching to an atomic notifier which allows us to
send events from atomic context
- also to that end store the debounce period in the GPIO descriptor
struct and not in the character device context struct
- while at it, also cover the corner-case of users introducing
changes over sysfs while others watch them via the character device
- don't report GPIO lines requested as interrupts as "used" to
user-space as it can still request them as GPIOs
New drivers:
- GPIO part of the MFD Congatec Board Controller
- PolarFire GPIO controller
- GPIOs on FTDI FT2232H
Driver improvements:
- use generic device property accessors instead of OF-specific ones
across many GPIO drivers (mpc8xxx, vf610, eic-sprd, davinci,
ts4900, xilinx, mvebu)
- use devres helpers to simplify error paths and either shrink or
entirely remove the driver's remove() callback (grgpio, amdpt,
menz127, max730x, ftgpio010, 74x164, ljca)
- use helper variables to store the address of pdev->dev and avoid
some line-breaks
- use device_for_each_child_node_scoped() to avoid having to put the
fwnode on breaks or errors (gpio-sim, gpio-dwapb, gpiolib-acpi)
- use a scoped bitmap to simplify the code and drop goto labels in
gpio-aggregator
- drop unneeded Kconfig dependencies on OF_GPIO (grgpio, mveby,
xilinx)
- add support for new models to gpio-aspeed, gpio-rockchip and
gpio-dwapb
- clean-up ACPI handling and some other bits in gpio-xgene-sb
- replace deprecated PCI functions in pcie-idio-24 and pci-idio-16
- allow to build davinci and mvebu drivers with COMPILE_TEST=y
- remove dead code in gpio-mb86s7x
- switch back to using platform_driver::remove() (after the
conversion to remove_new()) across the GPIO drivers
- remove remaining uses of GPIOF_ACTIVE_LOW across the tree and drop
this deprecated symbol
- convert the gpio-altera driver to no longer pull in the deprecated
legacy-of-mm-gpiochip.h header
- use of_property_present() instead of of_property_read_bool() in
gpiolib-of and gpio-rockchip
- allow to build the tegra186 driver on Tegra234 platforms in Kconfig
Late fixes:
- add a missing return value check after devm_kasprintf() to
gpio-grgpio
DT bindings:
- document the ngpios property of gpio-mmio
- add support for a new aspeed model
- fix the example for st,nomadik-gpio
Other:
- kernel doc and comments tweaks
- fix typos in TODO
- reorder headers alphabetically in some drivers
- fix incorrect format specifiers in gpio tools"

Pull ftrace updates from Steven Rostedt:
- Restructure the function graph shadow stack to prepare it for use
with kretprobes
With the goal of merging the shadow stack logic of function graph and
kretprobes, some more restructuring of the function shadow stack is
required.
Move out function graph specific fields from the fgraph
infrastructure and store it on the new stack variables that can pass
data from the entry callback to the exit callback.
Hopefully, with this change, the merge of kretprobes to use fgraph
shadow stacks will be ready by the next merge window.
- Make shadow stack 4k instead of using PAGE_SIZE.
Some architectures have very large PAGE_SIZE values which make its
use for shadow stacks waste a lot of memory.
- Give shadow stacks its own kmem cache.
When function graph is started, every task on the system gets a
shadow stack. In the future, shadow stacks may not be 4K in size.
Have it have its own kmem cache so that whatever size it becomes will
still be efficient in allocations.
- Initialize profiler graph ops as it will be needed for new updates to
fgraph
- Convert to use guard(mutex) for several ftrace and fgraph functions
- Add more comments and documentation
- Show function return address in function graph tracer
Add an option to show the caller of a function at each entry of the
function graph tracer, similar to what the function tracer does.
- Abstract out ftrace_regs from being used directly like pt_regs
ftrace_regs was created to store a partial pt_regs. It holds only the
registers and stack information to get to the function arguments and
return values. On several archs, it is simply a wrapper around
pt_regs. But some users would access ftrace_regs directly to get the
pt_regs which will not work on all archs. Make ftrace_regs an
abstract structure that requires all access to its fields be through
accessor functions.
- Show how long it takes to do function code modifications
When code modification for function hooks happen, it always had the
time recorded in how long it took to do the conversion. But this
value was never exported. Recently the code was touched due to new
ROX modification handling that caused a large slow down in doing the
modifications and had a significant impact on boot times.
Expose the timings in the dyn_ftrace_total_info file. This file was
created a while ago to show information about memory usage and such
to implement dynamic function tracing. It's also an appropriate file
to store the timings of this modification as well. This will make it
easier to see the impact of changes to code modification on boot up
timings.

Merge tag 'sched_ext-for-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext
Pull sched_ext updates from Tejun Heo:
- Improve the default select_cpu() implementation making it topology
aware and handle WAKE_SYNC better.
- set_arg_maybe_null() was used to inform the verifier which ops args
could be NULL in a rather hackish way. Use the new __nullable CFI
stub tags instead.
- On Sapphire Rapids multi-socket systems, a BPF scheduler, by
hammering on the same queue across sockets, could live-lock the
system to the point where the system couldn't make reasonable forward
progress.
This could lead to soft-lockup triggered resets or stalling out
bypass mode switch and thus BPF scheduler ejection for tens of
minutes if not hours. After trying a number of mitigations, the
following set worked reliably:
- Injecting artificial cpu_relax() loops in two places while
sched_ext is trying to turn on the bypass mode.
- Triggering scheduler ejection when soft-lockup detection is
imminent (a quarter of threshold left).
While not the prettiest, the impact both in terms of code complexity
and overhead is minimal.
- A common complaint on the API is the overuse of the word "dispatch"
and the confusion around "consume". This is due to how the dispatch
queues became more generic over time. Rename the affected kfuncs for
clarity. Thanks to BPF's compatibility features, this change can be
made in a way that's both forward and backward compatible. The
compatibility code will be dropped in a few releases.

A legitimate use (BPF cgroup release) of system_wq could saturate it

While the offending use was switched to a dedicated workqueue, use
the opportunity to bump WQ_MAX_ACTIVE four fold and document that
system workqueue shouldn't be saturated. Workqueue should add at
least a warning mechanism for cases where system workqueues are
saturated.
- Recent workqueue updates to support more flexible execution topology
