Along with RiscPC and SA1100, these are the last remaining Intel StrongARM
machines. The Corel NetWinder used to be particular popular in the late
1990s, but was discontinued during the bankruptcy of rebel.com in 2001.
The other machine is the DEC (later Intel) EBSA285 evaluation board that
was made in small numbers in 1997 for software developers.
The footbridge/netwinder platform was the main target for the first Debian
2.0 "Hamm" release on the Arm architecture back in 1998, but was dropped
in Debian 6.0 "Squeeze" in 2011, which only supported ARMv4T and higher
with the EABI based ports as ARMv4 hardware had fallen already out of
use by that time.

This platform is the oldest still supported machine, dating back
to the original 1994 ARM610 version. The only currently supported
configuration uses an ARMv4 StrongARM but still requires building
for ARMv3 because of the board design not supporting 16-bit
data access.
ARMv3 support has been removed in gcc-9, and the gcc-8 release
is already old but still supported for building the kernel.
The only set of machines that lacks support for 16-bit load/store
instructions (Alpha EV5 and older) was recently removed from
the kernel.
Since there is little hope of this being maintainable much
longer, plan to remove it in early 2027 while it is still expected
to mostly work.

Most of the old StrongARM1100 machines were removed two years ago as part
of a wider cleanup, the remaining four were left either because someone
showed interest in converting them to devicetree, or because they were
still supported by qemu and therefore useful to keep the platform alive.
None of the devicetree conversion actually happened, and qemu has
marked the platform as deprecated, so do the same in the kernel now.
If anyone is still running one of these four machines and planning
to keep updating their kernels, please speak up now so we can adapt
the plans as needed.
If nobody is found using StrongARM1100 any more, it can be removing
during 2027, leaving 7.3-LTS as the last longterm support kernel
for it.

In the 2021 board file removal, the gumstix and sharpsl
support was left around in order to make it easier to convert
more of the PXA platform to device tree, given that both
platforms had some level of support in qemu.
As far as I can tell, nobody has worked on additional DT
conversion in that time, and qemu has in turn deprecated
the entire PXA platform.
Schedule the remaining board files for removal now, as they
are unlikely to be of any help in the future. If anyone
wants to revive support for these machines, they can
obviously still contribute device tree based code and
work on updating the corresponding drivers.
Any drivers that are only usable on legacy PXA board files
can also get removed along with the boards, or saved by
adding devicetree support.

Following the deprecation of big-endian ARMv8 mode in arch/arm64 in commit
1cf89b6bf6 ("arm64: Kconfig: Make CPU_BIG_ENDIAN depend on BROKEN"),
this does the same for ARMv7 (and v6), leaving the code around but
disabled by default: There are no known products that make use of this
mode any more, and it only hangs around for testing that it still works.
At the moment, there are no known bugs with big-endian ARMv7 mode, but
it does break occasionally and require someone to fix it. By marking
the code as 'depends on BROKEN' now, it will no longer be covered by CI
testing. If any users remain, they can keep patching out the dependency
but are more likely to run into regressions.
The big-endian ARMv5 support (CONFIG_CPU_ENDIAN_BE32) in contrast is
still used on Intel IXP4xx platform, and is the only currently supported
mode there, so this one can still be enabled.
There is no timeline for actually removing the code at this point,
we will likely debate this if we ever remove IXP4xx support on arm,
or big-endian support on ARM64.

Only a very small number of machines remain that rely on
traditional board files with the ATAGS boot data instead
of devicetree, and we have not accepted new ones for
a decade.
Most of the remaining ones are on their way out of the
kernel, but the Kconfig option that controls ATAGS
is still enabled by default.
To reflect the actual status of ATAGS support and alert
the remaining users of upstream and out-of-tree platforms
with this, change it to being default-disabled and
add a dependency on CONFIG_EXPERT.
The board specific defconfig files that rely on ATAGS
are changed to turn on both EXPERT and ATAGS if they
were not doing that already, and the ones that explicitly
turned it off before no longer need to.

Support for SMP on ARM1136r0 has been broken for a while, and nobody
is working on fixing it. I had a plan to change ARMv6 support to no
longer coexist in a common kernel with ARMv7 CPUs but instead ARMv5 and
below. This would have addressed the problem, but after a recent mailing
list discussion, we concluded that an easier approach is to just forbid
ARM1136r0 CPU support on SMP-enabled kernels.
This mainly affects users of the Nokia N800/N810 tablets using an
OMAP2420 SoC, which is the only commercial product with an ARM1136r0
that is still supported by the kernel.
The other machines that are still in the same hardware catogory are:
- TI OMAP2420 H4 reference board
- TI OMAP2430 SDP software development platform
- Freescale/NXP i.MX31 Lite Development Kit
- Buglabs i.MX31 Bug 1.x prototype
- Arm Integrator/AP with CM1136JF-S core module
To my knowledge, none of these have any actual users aside from
reference boards being used to more easily test the platforms.
There are also a few ARM1136r1 machines, which implement the
ARMv6K SMP support (barriers, atomics and TLS):
- Eukrea CPUIMX35 reference platform
- Freescale/NXP i.MX35 Product Development Kit
- ARM Integrator/CP/IM-LT3 with ARM1136J Core Tile
- ARM Realview/EB with ARM1136J Core Tile
Again, these are mainly reference implementations rather than
actual products, but since they support ARMv6K, they should
continue to work correctly in SMP-enabled kernels. For the
ARM Core Tile, I have not found a datasheet but instead use
the revision based on what the respective virtual models
report.
All the other ARMv6 platforms use an ARM1176 with ARMv6K,
VMSAv7 and Trustzone support.
To avoid the broken configuration, annotate the ARM1136 based
machines with specific CPU_ARM1136R0 or CPU_ARM1136R2 symbols
in Kconfig and make the r0 variants depend on !SMP.

As discussed on the mailing lists, there is no way to build OABI userspace
binaries any more since gcc-4.8, and now support is also getting dropped in
binutils, which will make it impossible to build pure OABI kernels at some
point in the future.
I found no evidence of anyone still sing OABI userspace on embedded systems
that keep getting kernel updates, but there are a few desktop-class machines
that date back to the 1990s using Intel StrongARM processors that were
supported by old versions of Debian, Red Hat or the official Corel
Netwinder distribution.
Add a much stricter Kconfig dependency for both native OABI and OABI_COMPAT
enabled kernels, only allowing either of them to be selected when building
a kernel that targets a StrongARM based machine.

On ARMv4 and ARMv5, the default is still to build for OABI, with
CONFIG_AEABI disabled, even though distros and toolchains no longer
support OABI as a target.
Change the default to EABI for all architecture levels and change
the defconfig entries as follows:
- All machines that used to explicitly enable EABI can drop that line now
- Machines that are likely to actually use old distros and had NWFPE
enabled in combination with OABI (rpc, footrbridge, netwinder,
assabet, neponset) explicitly turn it on now.
- Machines that already had both EABI and NWFPE disabled in defconfig
(spear3xx, spear6xx) were likely not usable with either OABI or
EABI and now use EABI instead implicitly, making it more likely that
they could work.

pa_start >= arm_lowmem_limit, so pa_start < arm_lowmem_limit is guaranteed
as well.
When pa_end <= arm_lowmem_limit, pa_start < pa_end means start < end, so
the start >= end check is unreachable.
When pa_end > arm_lowmem_limit, end is clamped to __va(arm_lowmem_limit),
and pa_start < arm_lowmem_limit means start < end, so the check is

imx7_src_init() obtains two device_node references via
of_find_compatible_node() - one for "fsl,imx7d-src" and one for
"fsl,imx7d-gpc" - reusing the same np variable, but never calls
of_node_put() on either. On every i.MX7D boot up to two device_node
refcounts are leaked:
- The "fsl,imx7d-src" node is leaked both when of_iomap() fails (the
early return after the mapping) and when it succeeds, because np is
then overwritten by the second of_find_compatible_node() call
without releasing the prior reference.
- The "fsl,imx7d-gpc" node is leaked on every path leaving the
function after it is acquired.
Release each reference immediately after of_iomap() consumes the node.
of_iomap() maps the node's registers but does not retain a reference to
the device_node, so it is safe to put the node once mapped; this also
drops the first reference before np is reused for the second lookup.

imx_src_init() obtains a device_node reference via
of_find_compatible_node() matching "fsl,imx51-src" and uses it only to
call of_iomap(). It never releases that reference: on the success path
the function returns at the end without of_node_put(np), leaking one
device_node refcount on every boot of an i.MX5/6 platform.
Release the reference right after of_iomap(). of_iomap() maps the
node's registers but does not retain a reference to the device_node, so
the node can be put once the mapping is done. The early return on a NULL
np needs no put.

of_find_compatible_node() returns a device node with its reference count
incremented. mxc_init_irq() looks up the i.MX25 CCM node for of_iomap()
and the AVIC node for irq_domain_create_legacy(), but does not release
either temporary reference.
of_iomap() does not consume the node reference, and
irq_domain_create_legacy() takes its own fwnode reference for the domain.
Drop the temporary OF node references after each use.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize now
on the __ASSEMBLER__ macro that is provided by the compilers.
This is a completely mechanical patch (done with a simple "sed -i"
statement).

Replace sequences of of_machine_is_compatible() calls by single calls to
the of_machine_compatible_match() helper, to simplify the code, and to
reduce code size.
Note that this does have a slight performance impact on matching
platforms: while the C sequences terminated evaluation after a match,
(internal) of_device_compatible_match() calculates a matching score, and
thus always checks against all passed compatible values.

There are fewer devicetree updates this time that the last few ones, with
five SoC types getting added:
- Qualcomm Dragonwing IPQ9650 is a new wireless networking SoC using
four Cortex-A55 and one Cortex-A78 core, which is a significant
upgrade from older generations
- ZTE zx297520v3 is an older low-end wireless SoC using a single
Cortex-A53 core, which so far can only run 32-bit kernels. This brings
back the ZX family of chips that was removed in 2021 after support
for the original zx296702 and zx296718 chips was never completed.
- Renesas R-Car M3Le (R8A779MD) is a variant of the R-Car M3-N (R8A77965)
automotive SoC.
- Apple t8122 (M3) is the 2023 generation of their laptop SoCs,
which has now been reverse-engineered to the point of having initial
kernel support for five laptop models.
- ASPEED AST27xx is their first baseboard managment controller using
a 64-bit core, the Cortex-A35, following earlier generations using
ARMv5/v6/v7 CPUs.
These all come with one or more initial boards, and in total there
are 39 new boards getting added across SoC families, including:
- Two NAS boxes using the old Cortina Systems Gemini SoC based on
an ARMv4 FA526 CPU core
- 18 industrial embedded boards using NXP i.MX6/8/9 and LX2160A
SoCs from Variscite, Toradex and SolidRun, plus a number of
overlays for combinations with additional boards
- One new carrier board and SoM using TI K3 AM62x, in addition to
new overlays for older SoMs
- Two new boards using Spacemit K3 (no relation with TI) RISC-V
SoCs.
- Three phones from Google, Nothing and Motorola, all using Qualcomm
Snapdragon SoCs
- AST26xx BMC support for two server boards
While there is still a significant number of patches improving hardware
support for the existing boards across vendors (NXP, Qualcomm, Renesas,
Rockchips, Mediatek, ...), a much smaller number of cleanups and warning
fixes have made it in this time.

Cortex-A53 core, which so far can only run 32-bit kernels. This
brings back the ZX family of chips that was removed in 2021 after
support for the original zx296702 and zx296718 chips was never
completed.
- Renesas R-Car M3Le (R8A779MD) is a variant of the R-Car M3-N
(R8A77965) automotive SoC.
- Apple t8122 (M3) is the 2023 generation of their laptop SoCs, which
has now been reverse-engineered to the point of having initial
kernel support for five laptop models.
- ASPEED AST27xx is their first baseboard managment controller using
a 64-bit core, the Cortex-A35, following earlier generations using
ARMv5/v6/v7 CPUs.
These all come with one or more initial boards, and in total there are
39 new boards getting added across SoC families, including:
- Two NAS boxes using the old Cortina Systems Gemini SoC based on an
ARMv4 FA526 CPU core
- 18 industrial embedded boards using NXP i.MX6/8/9 and LX2160A SoCs
from Variscite, Toradex and SolidRun, plus a number of overlays for
combinations with additional boards
- One new carrier board and SoM using TI K3 AM62x, in addition to new
overlays for older SoMs
- Two new boards using Spacemit K3 (no relation with TI) RISC-V SoCs.
- Three phones from Google, Nothing and Motorola, all using Qualcomm
Snapdragon SoCs
- AST26xx BMC support for two server boards
While there is still a significant number of patches improving
hardware support for the existing boards across vendors (NXP,
Qualcomm, Renesas, Rockchips, Mediatek, ...), a much smaller number
of cleanups and warning fixes have made it in this time"

Core & protocols
----------------
- Work on removing rtnl_lock protection throughout the stack continues.
In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even tho
user space wants a dump of all netdevs, most of the time, the OOO
programming model results in repeating the dump for each netdev.
Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on retransmit
timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 > 40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot express
reqid changes or migrate Transport mode selectors. The new interface
identifies the SA via SPI and mark, supports reqid changes, address
family changes, encap removal, and uses an atomic create+install
flow under x->lock to prevent SN/IV reuse during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff
----------------
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto API
users, since it changed crypto transformation objects into reference-
-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the global
crypto API as obsolete and insecure.
Wireless
--------
- Major rework of station bandwidth handling, fixing issues with lower
capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter
---------
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions
---------
- Remove TLS + sockmap integration. TLS wants to pin user pages
to avoid a copy, and sockmap wants to write to the input stream.
More work on this integration is clearly needed, and we can't find
any users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from
the vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM needs,
AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit kernel)
interface in user namespaces. To be deleted completely, soon.
- Remove 5/10 MHz support from cfg80211/mac80211.
Drivers
-------
- Software:
- Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit).
- bonding: add knob to strictly follow 802.3ad for link state.
- New drivers:
- Alibaba Elastic Ethernet Adaptor (cloud vNIC).

- support Socket Direct (multi-PF) with switchdev offloads
- add a pool / frag allocator for DMA mapped buffers for control
objects, save memory on systems with 64kB page size

- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on
retransmit timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot
express reqid changes or migrate Transport mode selectors.
The new interface identifies the SA via SPI and mark, supports
reqid changes, address family changes, encap removal, and uses an
atomic create+install flow under x->lock to prevent SN/IV reuse
during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff:
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto
API users, since it changed crypto transformation objects into
reference-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the
global crypto API as obsolete and insecure.
Wireless:
- Major rework of station bandwidth handling, fixing issues with
lower capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter:
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions:
- Remove TLS + sockmap integration. TLS wants to pin user pages to
avoid a copy, and sockmap wants to write to the input stream. More
work on this integration is clearly needed, and we can't find any
users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from the
vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM
needs, AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit
kernel) interface in user namespaces. To be deleted completely,
soon.
- Remove 5/10 MHz support from cfg80211/mac80211.
Drivers:
- Software:
- Support DEVMEM/DMABUF Tx over NETMEM_TX_NO_DMA devices (netkit)
- bonding: add knob to strictly follow 802.3ad for link state
- New drivers:
- Alibaba Elastic Ethernet Adaptor (cloud vNIC).
- NXP NETC switch within i.MX94.
- DPLL:

- Add generic DPLL type, for daisy-chaining DPLLs (implement in ice).
- Ethernet high-speed NICs:
- Huawei (hinic3):
- enhance tc flow offload support with queue selection,
tunnels
- nVidia/Mellanox:
- avoid over-copying payload to the skb's linear part (up to
60% win for LRO on slow CPUs like ARM64 V2)
- expose more per-queue stats over the standard API
- support additional, unprivileged PFs in the DPU
configuration
- support Socket Direct (multi-PF) with switchdev offloads
- add a pool / frag allocator for DMA mapped buffers for
control objects, save memory on systems with 64kB page size
- take advantage of the ability to dynamically change RSS
table size, even when table is configured by the user

AppleTalk has been removed in MacOS X 10.6 (Snow Leopard), in 2009,
according to Wikipedia. We recently got a burst of AI generated
fixes to this protocol which nobody is reviewing.
Let AppleTalk follow AX.25 and hamradio out of the Linux tree.
We we will maintain the code at: github.com/linux-netdev/mod-orphan
for anyone interested in playing with it.
Retain the uAPI for now. No strong reason, simply because I suspect
keeping it will be less controversial.

Accelerate CRC64-NVME for 32-bit ARM by refactoring the arm64 NEON
intrinsics implementation to be shared by 32-bit and 64-bit.
Also apply a similar cleanup to the 32-bit ARM NEON implementation of

- Rework of /proc/interrupt handling:
/proc/interrupts was subject to micro optimizations for a long time,
but most of the low hanging fruit was left on the table. This rework
addresses the major time consuming issues:
- Printing a long series of zeros one by one via a format string
instead of counting subsequent zeros and emitting a string
constant.
- Simplify and cache the conditions whether interrupts should be printed
- Use a proper iteration over the interrupt descriptor xarray
instead of walking and testing one by one.
- Provide helper functions for the architecture code to emit the
architecture specific counters
- Convert the counter structure in x86 to an array, which
simplifies the output and add mechanisms to suppress unused
architecture interrupts, which just occupy space for
nothing. Adopt the new core mechanisms.
This adjusts the gdb scripts related to interrupt counter statitics
to work with the new mechanisms.
- Prevent a string overflow in the /proc/irq/$N/ directory name
creation code.

- Fix race where deferred probe timeout work could be permanently
canceled by using mod_delayed_work()
- Fix missing jiffies conversion in deferred_probe_extend_timeout()
- Guard timeout extension with delayed_work_pending() to prevent

- Use system_percpu_wq instead of the deprecated system_wq

- device:

dma_skip_sync, dma_ops_bypass, state_synced, dma_coherent,
of_node_reused, offline, offline_disabled) with flag-based
accessors using bit operations

- Move core device attributes to read-only memory
- Constify group array pointers in driver_add_groups() /

- device property:
- Fix fwnode reference leak in fwnode_graph_get_endpoint_by_id()
- Initialize all fields of fwnode_handle in fwnode_init()
- Provide swnode_get()/swnode_put() wrappers around kobject_get/put()
- Allow passing struct software_node_ref_args pointers directly to
PROPERTY_ENTRY_REF()
- driver_override:
- Migrate amba, cdx, vmbus, and rpmsg to the generic driver_override
infrastructure, fixing a UAF from unsynchronized access to
driver_override in bus match() callbacks
- Remove the now-unused driver_set_override()
- firmware loader:
- Fix recursive lock deadlock in device_cache_fw_images() when async
work falls back to synchronous execution
- Fix device reference leak in firmware_upload_register()
- platform:
- Pass KBUILD_MODNAME through the platform driver registration macro
to create module symlinks in sysfs for built-in drivers; move
module_kset initialization to a pure_initcall and tegra cbb
registration to core_initcall to ensure correct ordering
- Pass THIS_MODULE implicitly through a coresight_init_driver() macro
- sysfs:
- Upgrade OOB write detection in sysfs_kf_seq_show() from printk to
WARN
- Add return value clamping to sysfs_kf_read()
- Rust:
- ACPI:
- Fix missing match data for PRP0001 by exporting
acpi_of_match_device()
- Auxiliary:
- Replace drvdata() with dedicated registration data on
auxiliary_device. drvdata() exposed the driver's bus device
private data beyond the driver's own scope, creating ordering
constraints and forcing the data to outlive all registrations
that access it. Registration data is instead scoped structurally
to the Registration object, making lifecycle ordering enforced
by construction rather than convention.
- Rust-native device driver lifetimes (HRT):
- Allow Rust device drivers to carry a lifetime parameter on their
bus device private data, tied to the device binding scope -- the
interval during which a bus device is bound to a driver. Device
resources like pci::Bar<'a> and IoMem<'a> can be stored directly
in the driver's bus device private data with a lifetime bounded
by the binding scope, so the compiler enforces at build time that
they do not outlive the binding. This removes Devres indirection
from every access site and eliminates try_access() failure paths
in destructors.
Bus driver traits use a Generic Associated Type (GAT)
Data<'bound> to introduce the lifetime on the private data,
rather than parameterizing the Driver trait itself. Auxiliary
registration data, where the lifetime is not introduced by a
trait callback but must be threaded through Registration, uses
the ForLt trait (a type-level abstraction for types generic over
a lifetime).
- Misc:
- Fix DT overlayed devices not probing by reverting the broken
treewide overlay fix and re-running fw_devlink consumer pickup when
an overlay is applied to a bound device
- Use root_device_register() for faux bus root device; add sanity
check for failed bus init
- Fix dev_has_sync_state() data race with READ_ONCE() and move it to
base.h
- Avoid spurious device_links warning when removing a device while
its supplier is unbinding
- Switch ISA bus to dynamic root device
- Fix suspicious RCU usage in kernfs_put()
- Remove devcoredump exit callback
- Constify devfreq_event_class

- Pass KBUILD_MODNAME through the platform driver registration macro
to create module symlinks in sysfs for built-in drivers; move
module_kset initialization to a pure_initcall and tegra cbb
registration to core_initcall to ensure correct ordering
- Pass THIS_MODULE implicitly through a coresight_init_driver() macro
sysfs:
- Upgrade OOB write detection in sysfs_kf_seq_show() from printk to
WARN
- Add return value clamping to sysfs_kf_read()
Rust:
- ACPI:
Fix missing match data for PRP0001 by exporting
acpi_of_match_device()
- Auxiliary:
Replace drvdata() with dedicated registration data on
auxiliary_device. drvdata() exposed the driver's bus device private
data beyond the driver's own scope, creating ordering constraints
and forcing the data to outlive all registrations that access it.
Registration data is instead scoped structurally to the
Registration object, making lifecycle ordering enforced by
construction rather than convention.
- Rust-native device driver lifetimes (HRT):
Allow Rust device drivers to carry a lifetime parameter on their
bus device private data, tied to the device binding scope -- the
interval during which a bus device is bound to a driver. Device
resources like pci::Bar<'a> and IoMem<'a> can be stored directly in
the driver's bus device private data with a lifetime bounded by the
binding scope, so the compiler enforces at build time that they do
not outlive the binding. This removes Devres indirection from every
access site and eliminates try_access() failure paths in
destructors.
Bus driver traits use a Generic Associated Type (GAT) Data<'bound>
to introduce the lifetime on the private data, rather than
parameterizing the Driver trait itself. Auxiliary registration
data, where the lifetime is not introduced by a trait callback but
must be threaded through Registration, uses the ForLt trait (a
type-level abstraction for types generic over a lifetime).
Misc:
- Fix DT overlayed devices not probing by reverting the broken
treewide overlay fix and re-running fw_devlink consumer pickup when
an overlay is applied to a bound device
- Use root_device_register() for faux bus root device; add sanity
check for failed bus init
- Fix dev_has_sync_state() data race with READ_ONCE() and move it to
base.h
- Avoid spurious device_links warning when removing a device while
its supplier is unbinding
- Switch ISA bus to dynamic root device
- Fix suspicious RCU usage in kernfs_put()
- Remove devcoredump exit callback
- Constify devfreq_event_class"

Pull misc vfs updates from Christian Brauner:
"Features:
- Reduce pipe->mutex contention by pre-allocating pages outside the
lock in anon_pipe_write().
anon_pipe_write() called alloc_page() once per page while holding
pipe->mutex. The allocation can sleep doing direct reclaim and runs
memcg charging, which extends the critical section and stalls any
concurrent reader on the same mutex. Now up to 8 pages are
pre-allocated before the mutex is taken, leftovers are recycled
into the per-pipe tmp_page[] cache before unlock, and any remainder
is released after unlock, keeping the allocator out of the critical
section on both sides. On a writers x readers sweep with 64KB
writes against a 1 MB pipe throughput improves 6-28% and average
write latency drops 5-22%; under memory pressure - when the cost of
holding the mutex across reclaim is highest - throughput improves
21-48% and latency drops 17-33%. The microbenchmark is added to
selftests.
- uaccess/sockptr: fix the ignored_trailing logic in
copy_struct_to_user() to behave as documented and the usize check
in copy_struct_from_sockptr() for user pointers, and add
copy_struct_{from,to}_bounce_buffer() and copy_struct_to_sockptr()
helpers for upcoming users (IPPROTO_SMBDIRECT, IPPROTO_QUIC).
- bpf: add a sleepable bpf_real_inode() kfunc that resolves the real
inode backing a dentry via d_real_inode(). On overlayfs the inode
attached to the dentry doesn't carry the underlying device
information; this is used by the filesystem restriction BPF program
that was merged into systemd.
- docs: add guidelines for submitting new filesystems, motivated by
the maintenance burden abandoned and untestable filesystems impose
on VFS developers, blocking infrastructure work like folio
conversions and iomap migration.
Fixes:
- libfs: set SB_I_NOEXEC and SB_I_NODEV by default in init_pseudo()
and drop the now-redundant assignments in callers. This began as a
one-line dma-buf fix for a path_noexec() warning; a pseudo
filesystem has no reason not to set SB_I_NOEXEC. All init_pseudo()
callers were audited: the only visible effect is on dma-buf where
SB_I_NOEXEC silences the warning.
- Handle set_blocksize() failures in legacy filesystems (bfs, hpfs,
qnx4, jfs, befs, affs, isofs, minix, ntfs3, omfs). Mounting a
device with a sector size > PAGE_SIZE crashed roughly half of them;
the rest had the same missing error handling pattern. Plus a
follow-up releasing the superblock buffer_head when setting the
minix v3 block size fails.
- mount: honour SB_NOUSER in the new mount API.
- fs/fcntl: fix a SOFTIRQ-unsafe lock order in fasync signaling by
switching the process-group paths of send_sigio() and send_sigurg()
from read_lock(&tasklist_lock) to RCU, matching the single-PID
path.
- vfs: add an FS_USERNS_DELEGATABLE flag and set it for NFS, fixing
delegated NFS mounts (fsopen() in a container with the mount
performed by a privileged daemon) that broke when non-init
s_user_ns was tied to FS_USERNS_MOUNT.
- selftests/namespaces: fix a hang in nsid_test where an unreaped
grandchild kept the TAP pipe write-end open, a waitpid(-1) race in
listns_efault_test, and a false FAIL on kernels without listns()
where the tests should SKIP.
- filelock: fix the break_lease() stub signature for
CONFIG_FILE_LOCKING=n.
- init/initramfs_test: wait for the async initramfs unpacking before
running; the test and do_populate_rootfs() share the parser state.
- fs/coredump: reduce redundant log noise in
validate_coredump_safety().
- iomap: pass the correct length to fserror_report_io() in
__iomap_write_begin().
- backing-file: fix the backing_file_open() kerneldoc.
Cleanups:
- initramfs: refactor the cpio hex header parsing to use hex2bin()
instead of the hand-rolled simple_strntoul() which is reverted, and
extend the initramfs KUnit tests to cover header fields with 0x
prefixes.
- Replace __get_free_pages() and friends with kmalloc()/kzalloc()
across quota, proc, ocfs2/dlm, nilfs2, nfs, nfsd, libfs, jfs, jbd2,
isofs, fuse, select, namespace, configfs, binfmt_misc, bfs, and the
do_mounts init code - part of the larger work of replacing page
allocator calls with kmalloc().
- Use clear_and_wake_up_bit() in unlock_buffer() and
journal_end_buffer_io_sync() instead of open-coding the sequence.
- Drop unused VFS exports: unexport drop_super_exclusive(), remove
start_removing_user_path_at(), and fold __start_removing_path()
into start_removing_path().
- fs/read_write: narrow the __kernel_write() export with
EXPORT_SYMBOL_FOR_MODULES().
- vfs: uapi: retire octal and hex constants in favor of (1 << n) for
the O_ flags. Finding a free bit for a new flag across the
architectures was needlessly hard with the mixed bases.
- dcache: add extra sanity checks of dead dentries in dentry_free()
via a new DENTRY_WARN_ONCE() that also prints d_flags.
- iov_iter: use kmemdup_array() in dup_iter() to harden the
allocation against multiplication overflow.
- fs/pipe: write to ->poll_usage only once.
- vfs: remove an always-taken if-branch in find_next_fd().
- dcache: use kmalloc_flex() for struct external_name in __d_alloc().
- namei: use QSTR() instead of QSTR_INIT() in path_pts().
- sync_file_range: delete dead S_ISLNK code.
- Comment fixes: retire a stale comment in fget_task_next() and fix
assorted spelling mistakes"

ARM: rockchip: keep reset control around
soc: microchip: mpfs-sys-controller: fix resource leak on probe error
Remove sun4i_ss_rng, as it is insecure and unused:
- It has multiple vulnerabilities. sun4i_ss_prng_seed() is missing
locking and has a buffer overflow. sun4i_ss_prng_generate() fails to
fill the entire buffer with cryptographic random bytes, because it
rounds the destination length down and also doesn't actually wait for
the hardware to be ready before pulling bytes from it.
- No user of this code is known. It's usable only theoretically via the
"rng" algorithm type of AF_ALG. But userspace actually just uses the
actual Linux RNG (/dev/random etc) instead. And rng_algs don't
contribute entropy to the actual Linux RNG either. (This may have
been confused with hwrng, which does contribute entropy.)
The sun4i_ss_prng_seed() buffer overflow was reported by Tianchu Chen
and discovered by Atuin - Automated Vulnerability Discovery Engine
There's no point in fixing all these vulnerabilities individually when
this is unused code, so let's just remove it.

PCMCIA is almost completely obsolete (the last computers supporting it
natively were from ~2009), and the general consensus [1] seems to be
that support for it should be gradually removed from the kernel.
In 2023, an initial step of removing all the PCMCIA char drivers was
taken in commit 9b12f050c7 ("char: pcmcia: remove all the drivers"),
and that has not been reverted, so it seems logical to continue this
process by removing more low-hanging fruit.
These three Bluetooth drivers have had no meaningful changes since
their status was discussed in 2022 [2], and are unlikely to have any
remaining users. The latest functional change to any of them was a
patch to bluecard_cs to fix LED blinking behavior in 2017. The other
two drivers have not had any meaningful changes made since 2007. Remove
them.
Note that even with these drivers removed, it is still possible to use
other PCMCIA Bluetooth cards that present themselves as a standard
serial port via serial_cs and hciattach while the serial_cs driver is
still present.

Commit 7af5b901e8 ("ARM: 9358/2: Implement PAN for LPAE by TTBR0
page table walks disablement") implemented PAN for LPAE kernels by
setting TTBCR.EPD0 on every kernel entry, disabling TTBR0 page-table
walks while running in kernel mode. The commit correctly updated
cpu_suspend() in arch/arm/kernel/suspend.c, but missed two other code
paths that switch the CPU to the identity mapping before jumping to
low-PA (TTBR0-range) physical addresses:
1. setup_mm_for_reboot() in arch/arm/mm/idmap.c, used by the kexec
reboot path. With TTBCR.EPD0 still set, the subsequent branch to
the identity-mapped cpu_v7_reset causes a PrefetchAbort because the
TTBR0 page-table walk needed to resolve the identity-mapped address
is disabled. This manifests as a hard hang or "bad PC value" panic
on LPAE kernels booted on CPUs that strictly enforce EPD0 for
instruction fetch (e.g. Cortex-A53 in AArch32 mode) while the same
image may accidentally work on Cortex-A15 due to microarchitectural
differences in EPD0 enforcement.
2. arch_restore_image() in arch/arm/kernel/hibernate.c, which calls
cpu_switch_mm(idmap_pgd, &init_mm) directly without going through
setup_mm_for_reboot(), leaving TTBCR.EPD0 set while the identity
mapping is active.
Fix both sites by calling uaccess_save_and_enable() before switching
to the identity mapping, mirroring what the original commit did for
cpu_suspend().

Commit 44e9a3bb76 ("ARM: 9430/1: entry: Do a dummy read from
VMAP shadow") added a dummy read from the KASAN VMAP stack shadow in
__switch_to(). The read uses ldr, but the KASAN shadow address is
byte-granular and is not guaranteed to be word aligned.
ARMv5 faults unaligned word loads. With CONFIG_KASAN_VMALLOC and
CONFIG_VMAP_STACK enabled, ARM926/VersatilePB crashes in __switch_to()
with an alignment exception before reaching init.
Use ldrb for the dummy shadow access. The code only needs to fault in the
shadow mapping if the stack shadow is missing, so a byte load is sufficient
and matches the granularity of KASAN shadow memory.

For CPUs before ARMv6, __raw_readw() and __raw_writew() are implemented
as C volatile halfword accesses so the compiler can generate an access
sequence that is safe for those machines. With KASAN enabled, those C
accesses are instrumented as normal memory accesses.
That is not valid for MMIO. On ARM926/VersatilePB with KASAN enabled,
PL011 probing traps in __asan_store2() while registering the UART, because
the instrumented writew() tries to check KASAN shadow for an MMIO address.
Keep the existing volatile halfword access, but move the ARMv5 definitions
into __no_kasan_or_inline functions so raw MMIO halfword accesses are not
instrumented by KASAN. The ARMv6-and-newer inline assembly path is
unchanged.

This driver has no purpose. It doesn't feed into the Linux RNG, nor
does it implement the hwrng interface. It is accessible only via the
"rng" algorithm type of AF_ALG, which isn't used in practice. Everyone
uses either the Linux RNG, or rarely /dev/hwrng.
Moreover, this is a PRNG whose only source of entropy is the 160-bit
seed the user passes in. So this can be used only by a user who already
has a source of cryptographically secure random numbers, such as
/dev/random. Which they can, and do, just use in the first place.
Just remove this driver. There's no need to keep useless code around.
Note that the other crypto_rng drivers in drivers/crypto/ are similarly
unused and are being removed too. This commit just handles exynos-rng.

The do_bad_IRQ() macro simply calls handle_bad_irq() with a lock around
it. It also carries a comment stating that uses of it should be
replaced. According to commit aec0095653 ("irqchip: gic: Call
handle_bad_irq() directly"), which replaced another use of
do_bad_IRQ(), locking the IRQ descriptor is not necessary for error
reporting. Therefore, replace all uses of do_bad_IRQ() with calls to

The Kconfig logic for selecting the scheduler clocksource on
NXP Vybrid (VF610) uses a `choice` block restricted to 32-bit ARM. This
prevents 64-bit architectures, such as the NXP S32 family, from enabling
the NXP Periodic Interrupt Timer (PIT) driver (CONFIG_NXP_PIT_TIMER).
Relocate the NXP clocksource selection from arch/arm/mach-imx/Kconfig to
drivers/clocksource/Kconfig. This allows the configuration to be shared
across different architectures.
Update the selection to include support for ARCH_S32 and add a "None"
option restricted to ARCH_S32, since Vybrid lacks the ARM Architected
Timer. The Vybrid Global Timer option is restricted to ARCH_MULTI_V7
SOC_VF610 platforms to prevent it from being visible on Cortex-M4 builds,
which lack the ARM Global Timer hardware.

The only user of PCBC mode (Propagating Cipher Block Chaining mode) was
net/rxrpc/rxkad.c, which now uses local code instead.
While PCBC was an interesting cryptographic experiment, it has largely
been relegated to the history books and academic exercises. It is
non-parallelizable (i.e., very slow) and doesn't actually achieve the
integrity properties it was apparently intended to achieve.
Remove support for it from the crypto API.

Remove the insecure FCrypt block cipher from the crypto API. Its only
user was net/rxrpc/, but now net/rxrpc/ implements it locally. The
crypto API implementation is no longer needed.
For some additional context: FCrypt was designed in 1988 and is
essentially a weakened version of DES. It has the same 56-bit key size
as DES, which is easily brute forced. Moreover, it's cryptographically
weak and doesn't even provide the intended 56-bit security level. Its
author considers it to be a mistake, as well
(https://lists.openafs.org/pipermail/openafs-devel/2000-December/005320.html).
But fortunately this 1980s-era homebrew block cipher was never adopted
outside of net/rxrpc/. So its code can just be kept there.

The text display code used in the Risc PC kernel image decompression
code uses arch/arm/boot/compressed/font.c, which includes
lib/fonts/font_acorn_8x8.c, which further includes <linux/font.h>.
Since commit 97df896024 ("lib/fonts: Provide helpers for calculating
glyph pitch and size") <linux/font.h> contains inline functions that
require __do_div64, which is not linked into the ARM kernel
decompressor. This makes Risc PC zImages fail to build.
Resolve this issue by defining the BOOTLOADER symbol and use it to avoid
a static declaration of the acorndata_8x8 symbol. That way it can be
referenced by the arm bootloader, and other static math functions and
symbols (like __do_div64) stay static and don't get unneccesary included
in the ARM kernel bootloader decompressor object file.

Now, Simple Audio Card "platform data style" is no longer correctly working
during almost this 10 years. but we have not get such report.
Let's remove Sound support from SuperH ecovec24/7724se, and remove
Simple Audio Card platform data style.

to build or boot failures in certain configs.
- Work around a Rust compiler bug (already fixed for Rust 1.98.0) thats
lead to boot failures in certain configs due to missing 'uwtable'
LLVM module flags.
- Support a Rust compiler change (starting with Rust 1.98.0) in the

A recent build failure[1] exposed the diffculty of working with the
current octal and hex definitions of O_ flags when trying to find a gap
for a new flag. This difficulty is compounded by the fact that O_ flags
may have architectural specific values.
Replace the hex/octal #defines, which are hard to parse when looking for
free bits, with explicit bit shifts like (1 << 11). Also, add comments
that identify which architectures redefine some of the seemingly free
("cursed") bits in uapi/asm-generic/fcntl.h. These should not be used to
define new O_ flags (for now, at least).
The translastion was done with Claude Opus 4.8, and verified with a
(non-AI) gawk script. The accounting of which architectures claim
which bit-gaps in uapi/asm-generic/fcntl.h is also done by hand.

number of small issues found in firmware drivers (tee, optee, qcomtee,
qcom ice, exynos acpm) drivers through various tools. This is about
error handling, resource leaks, concurrency and a use-after-free bug.
The fixes for the Qualcomm ICE driver also introduce interface changes

Outside of firmware drivers, there are a few fixes across the tree:
- Minor driver code mistakes in the Atmel EBI memory controller,
the i.MX soc ID driver and socfpga boot logic
- A defconfig change to avoid a boot time regression on multiple
qualcomm boards
- Device tree fixes for qualcomm, at91 and gemini, addressing

Replace the vendor-specific PHY compatible string with the generic
ethernet-phy-ieee802.3-c22 compatible.
The marvell,88E1510 compatible is listed in whitelist_phys[] and is
never matched against a PHY driver. PHY devices are expected to use
the generic ethernet-phy-ieee802.3-c22 compatible unless a specific
MDIO driver match is required.
The 88E1510 is compatible with Clause 22 PHY devices, so use the
generic compatible string instead.

The edt,edt-ft5x06 compatible is not referenced in
drivers/input/touchscreen/edt-ft5x06.c and is not documented.
There is no publicly available datasheet or binding information that
distinguishes edt-ft5206/ft5306/ft5406 variants and the driver treats these
FT5x06-family controllers with the same configuration model. So switch to
the lowest common and documented baseline compatible edt,edt-ft5206.
Fix below CHECK_DTBS warnings:
arch/arm/boot/dts/nxp/imx/imx53-m53menlo.dtb: /soc/bus@60000000/i2c@63fc8000/touchscreen@38: failed to match any schema with compatible: ['edt,edt-ft5x06']
ABI impact consideration:
Not affect Linux kernel. The I2C subsystem uses a legacy fallback mechanism
where it strips the vendor prefix from the compatible string to derive the
client name, resulting in edt-ft5x06
{ .name = "edt-ft5x06", .driver_data = (long)&edt_ft5x06_data },
After this, the driver was actively binding to these devices based on the
compatible string.

The mss2_pci_init() function contains a check for the ARM machine ID
via the machine_is_mss2() macro. The board concerned now supports only
FDT booting, which does not use machine IDs, and therefore the code
should be updated to check the DT compatible property instead. The
machine was converted to FDT booting in commit fbf04d814d ("ARM:
orion5x: convert Maxtor Shared Storage II to the Device Tree"). The
presence of this machine ID check prevents the removal of machine IDs
no longer used by the kernel from arch/arm/tools/mach-types, because
the machine_is_*() macros are generated from mach-types. To resolve
this issue, use of_machine_is_compatible() instead.

Chromium/Depthcharge bootloaders may dynamically add a few device nodes
to a system's DTB under a /firmware node. A typical DT looks something
like the following:
/ {
firmware {
ranges;
coreboot {
compatible = "coreboot";
reg = <...>;
...;
};
};
};
Notably, the /firmware node has an empty 'ranges', but does not have
address/size-cells.
Commit 6e5773d52f ("of/address: Fix WARN when attempting translating
non-translatable addresses") started requiring #address-cells for a
device's parent if we want to use the reg resource in a device node.
This leads to errors like the following:
[ 7.763870] coreboot_table firmware:coreboot: probe with driver coreboot_table failed with error -22
Add appropriate #{address,size}-cells to work around the problem.
Note that Google has also patched the Depthcharge bootloader source to
add {address,size}-cells [1], but bootloader updates are typically
delivered only via Google OS updates. Not all users install Google
software updates, and even if they do, Google may not produce updated
binaries for all/older devices.

Adds the DT nodes needed for ethernet support for Asus Kommando, with
phy mode set to rgmii-id.
When this DT was originally added, the phy mode was set to rgmii (which
was incorrect). It was suggested to remove networking support from the
DT till the Aspeed networking driver was patched so that the correct phy
mode could be used.
The discussion in [1] mentions that u-boot was inserting clk delays that
weren't needed, which resulted in needing to set the phy mode in linux
to rgmii incorrectly. The solution suggested there was to patch u-boot to
no longer insert these clk delays and use rgmii-id as the phy mode for
any future DTs added to linux.
This DT was tested (on the OpenBMC u-boot fork [2]) with a u-boot DT
modified to insert clk delays of 0 (instead of patching u-boot itself).
[3] adds a u-boot DT for this device (without networking) and describes
how to patch it to add networking support. If this patched DT is used,
then networking works with rgmii-id phy mode in both u-boot and linux.

Quite some architectures have four character wide acronyms for architecture
specific interrupts like IPI, NMI, etc.
The default precision of printing the Linux device interrupt numbers is
three, which causes quite some code to play games with adding or omitting
space after the acronym and the colon in order to keep the per CPU numbers
properly aligned.
Increase the default number precision to four in the core code and get rid
of the space games all over the place. At the same time align all
architecture specific descriptor texts left so that they show up in the
same column as the interrupt chip names, which makes the output more
uniform accross architectures. Fix up the GDB script to this new scheme as

Troy Mitchell <troy.mitchell@linux.spacemit.com> says:
On some SoCs (e.g. SpacemiT K3), multiple I2S controllers share the
same physical BCLK. When one controller is already streaming, the
others must use hw_params that result in the same BCLK rate, otherwise
the shared clock would be reconfigured and corrupt the active stream.
This series adds framework-level support for this constraint:
Patch 1 adds the dt-bindings for the spacemit,k3-i2s compatible.
The K3 SoC uses the same I2S IP as K1 but requires additional clocks:
a dedicated sysclk_div, along with c_sysclk and c_bclk which are
shared across multiple I2S controllers.
Patch 2 adds a DEFINE_GUARD wrapping snd_soc_card_mutex_lock() and
snd_soc_card_mutex_unlock() so that scope-based locking picks up the
SND_SOC_CARD_CLASS_RUNTIME lockdep subclass.
Patch 3 adds the constraint logic in soc-pcm.c. During PCM open,
every DAI that has a bclk clock pointer gets a hw_rule registered
unconditionally. The rule callback runs at hw_refine time: it scans
the card for an active peer sharing the same physical BCLK (via
clk_is_match()) that has already completed hw_params, then constrains
the current stream's rate to match the established BCLK rate. The
first DAI to complete hw_params is unconstrained; subsequent DAIs
must match. Two modes are supported:
- Default (I2S): BCLK = rate * channels * sample_bits. The rule
derives the valid rate range from the current channel and
sample_bits intervals.
- Explicit ratio (TDM): if the driver sets dai->bclk_ratio
(e.g. slots * slot_width), the rule computes the single valid
rate as active_bclk_rate / bclk_ratio.
This series was prompted by review feedback on the SpacemiT K3 I2S
series, where a vendor-specific fixed-sample-rate property was rejected
in favor of a generic framework solution:

- Fix reporting MISSED EVENTS in trace iterator
When the "trace" file is read with tracing enabled, if the writer
were to pass the iterator reader, it resets, sets a "missed_events"
flag and continues. The tracing output checks for missed events and
if there are some, it prints out "[LOST EVENTS]" to let the user
know events were dropped.
But the clearing of the missed_events happened when the tracing system
queried the ring buffer iterator about missed events. This was premature
as the ring buffer is per CPU, and the tracing code reads all the
CPU buffers and checks for missed events when it is read. If the
CPU iterator that had missed events isn't printed next, the output
for the LOST EVENTS is lost.
Clear the missed_events flag when the iterator moves to the next event
and not when the missed_events flag is queried. Also clear it on reset.
- Flush and stop the persistent ring buffer on panic
On panic the persistent ring buffer is used to debug what caused the
panic. But on some architectures, it requires flushing the memory
from cache, otherwise, the ring buffer persistent memory may not have
the last events and this could also cause the ring buffer to be
corrupted on the next boot.
- Fix nr_subbufs initialization in simple_ring_buffer_init_mm
The remote simple ring buffer meta data nr_subbufs is initialized
too early and gets cleared later on, making it zero and not reflect
the actual number of sub-buffers.
- Fix unload_page for simple_ring_buffer init rollback
On error, the pages loaded need to be unloaded. To unload a page
it is expected that: page = load_page(va); -> unload_page(page).
But the code was doing: unload_page(va) and not unload_page(page).
- Create output file from cmd_check_undefined
The check for undefined symbols checks if the file *.o.checked exists
and if so it skips doing the work. But the *.o.checked file never
was created making every build do the work even when it was already
done previously.

ring-buffer: Flush and stop persistent ring buffer on panic
ring-buffer: Fix reporting of missed events in iterator
On real hardware, panic and machine reboot may not flush hardware cache
to memory. This means the persistent ring buffer, which relies on a
coherent state of memory, may not have its events written to the buffer
and they may be lost. Moreover, there may be inconsistency with the
counters which are used for validation of the integrity of the
persistent ring buffer which may cause all data to be discarded.
To avoid this issue, stop recording of the ring buffer on panic and
flush the cache of the ring buffer's memory.

The Prism54 SPI driver hardcodes GPIO numbers and expects users to
pass them as module parameters, apparently a relic from its life as a
staging driver. This works because there is only one user, the Nokia
N8x0 tablet.
Convert this to the gpio descriptor interface and DT based probing
to improve this and simplify the code at the same time.

instead of "LPOUT" in the gpio-line-names array. Fix these typos so the
pin names consistently match the LPOUT0-4 signals they belong to.

Move the divergent adc1 channel definitions out of the common
mecio1-io.dtsi file and into the specific Revision 0 and Revision 1
board files.
The original common file contained incorrect schematic labels for the
Revision 0 hardware (e.g., labeling ana0 as p24v_hpdcm instead of
ain_aux0) and failed to account for physical signal routing changes
between the board revisions.
Retain only the strictly shared channels in the common include file. Map
the correct channels and schematic labels directly within
stm32mp151c-mecio1r0.dts and stm32mp153c-mecio1r1.dts.
Crucially, ensure that the required 200us sample time follows the
phint1_ain signal to its new physical location on channel 3 for the
Revision 1 hardware.

Increase the minimum ADC sample times for all configured channels on
ADC1 and ADC2 to ensure measurement accuracy meets specifications.
The default 5us sample time is insufficient for the internal sampling
capacitor to fully charge. Increase the default time to 20us to relax
the input impedance requirements.
Additionally, the phint0_ain and phint1_ain channels require a much
longer sampling period due to their specific circuit design. Increase
their sample times to 200us. Remove stale comments regarding clock
cycles that no longer match the updated timings.

Switch the ADC reference supply from the general 3.3V rail to the
internal 2.5V VREFBUF regulator. The ADC circuits on this board are
designed for the internal 2.5V reference. Without this change, all ADC
measurement values are incorrect.

Update several Anacapa SGPIO line names to match the existing platform
hardware design and the signal names consumed by userspace monitoring.
The previous names did not match the actual Anacapa SGPIO usage. Some
lines were named as CPU or CPU power-good signals, but they are wired
and used on Anacapa for EDSFF presence, EDSFF power-good, boot EDSFF
presence, and thermal-trip assertion monitoring.
Correct the mappings as follows:
PWRGD_PVDDCR_SOC_P0 -> L_PRSNT_EDSFF0_N
PWRGD_PVDDIO_P0 -> L_PRSNT_EDSFF1_N
PWRGD_PVDDIO_MEM_S3_P0 -> R_PRSNT_EDSFF2_N
PWRGD_CHMP_CPU0_FPGA -> R_PRSNT_EDSFF3_N
PWRGD_CHIL_CPU0_FPGA -> HPM_EDSFF_PG
EAM2_CPU_MOD_PWR_GD_R -> PRSNT_EDSFF_BOOT_N
CPU0_SP7R1 -> L_EDSFF0_PG
CPU0_SP7R2 -> L_EDSFF1_PG
CPU0_SP7R3 -> R_EDSFF2_PG
CPU0_SP7R4 -> R_EDSFF3_PG
HPM_AMC_THERMTRIP_R_L -> AMC_THERMTRIP_ASSERT
FM_CPU0_THERMTRIP_N -> CPU_THERMTRIP_ASSERT
The left-side EDSFF slots are numbered as EDSFF0 and EDSFF1 to match
the platform slot numbering used by userspace. The thermtrip names are
also updated to describe the asserted condition monitored by userspace
instead of the raw active-low signal names.
This is a naming correction for the existing Anacapa hardware design.
There is no new board revision or underlying hardware change involved.
