The NAND controller size-cells should be 0 per DT bindings.
Fix the following warning produces by DT bindings check:
"
nand-controller@33002000: #size-cells:0:0: 0 was expected
nand-controller@33002000: Unevaluated properties are not allowed ('#address-cells', '#size-cells' were unexpected)
"
Fix the missing space in node name too.

Recent changes to the thermal framework has made the trip
points (trips) for thermal zones compulsory, which made
the Ux500 DTS files break validation and also stopped
probing because of similar changes to the code.
Fix this by adding an "outer bounding box": battery thermal
zones should not get warmer than 70 degress, then we will
shut down.

Enable sgpio node on pcb8291 as this is needed to be able to control
the LEDs on this board. Otherwise the LEDs support on the board will
not be available.
On the other board pcb8309 the sgpio is already enabled because it
needed to access the SFP ports.

Fix our design flaw in supply voltage distribution on the Quad and QuadPlus
based boards.
The problem is that we supply the SoC cache (VDD_CACHE_CAP) from VDD_PU
instead of VDD_SOC. The VDD_PU internal regulator can be disabled by PM
if VPU or GPU is not used. If that happens the system freezes. To prevent
that configure the reg_pu regulator to be always on.

Pull more random number generator updates from Jason Donenfeld:
"This time with some large scale treewide cleanups.
The intent of this pull is to clean up the way callers fetch random
integers. The current rules for doing this right are:
- If you want a secure or an insecure random u64, use get_random_u64()
- If you want a secure or an insecure random u32, use get_random_u32()
The old function prandom_u32() has been deprecated for a while
now and is just a wrapper around get_random_u32(). Same for
get_random_int().
- If you want a secure or an insecure random u16, use get_random_u16()
- If you want a secure or an insecure random u8, use get_random_u8()
- If you want secure or insecure random bytes, use get_random_bytes().
The old function prandom_bytes() has been deprecated for a while
now and has long been a wrapper around get_random_bytes()
- If you want a non-uniform random u32, u16, or u8 bounded by a
certain open interval maximum, use prandom_u32_max()
I say "non-uniform", because it doesn't do any rejection sampling
or divisions. Hence, it stays within the prandom_*() namespace, not
the get_random_*() namespace.
I'm currently investigating a "uniform" function for 6.2. We'll see
what comes of that.
By applying these rules uniformly, we get several benefits:
- By using prandom_u32_max() with an upper-bound that the compiler
can prove at compile-time is ≤65536 or ≤256, internally
get_random_u16() or get_random_u8() is used, which wastes fewer
batched random bytes, and hence has higher throughput.
- By using prandom_u32_max() instead of %, when the upper-bound is
not a constant, division is still avoided, because
prandom_u32_max() uses a faster multiplication-based trick instead.
- By using get_random_u16() or get_random_u8() in cases where the
return value is intended to indeed be a u16 or a u8, we waste fewer
batched random bytes, and hence have higher throughput.
This series was originally done by hand while I was on an airplane
without Internet. Later, Kees and I worked on retroactively figuring
out what could be done with Coccinelle and what had to be done
manually, and then we split things up based on that.
So while this touches a lot of files, the actual amount of code that's
hand fiddled is comfortably small"

Rather than truncate a 32-bit value to a 16-bit value or an 8-bit value,

Pull MM updates from Andrew Morton:
- Yu Zhao's Multi-Gen LRU patches are here. They've been under test in
linux-next for a couple of months without, to my knowledge, any
negative reports (or any positive ones, come to that).
- Also the Maple Tree from Liam Howlett. An overlapping range-based
tree for vmas. It it apparently slightly more efficient in its own
right, but is mainly targeted at enabling work to reduce mmap_lock
contention.
Liam has identified a number of other tree users in the kernel which
could be beneficially onverted to mapletrees.
Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat
at [1]. This has yet to be addressed due to Liam's unfortunately
timed vacation. He is now back and we'll get this fixed up.
- Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses
clang-generated instrumentation to detect used-unintialized bugs down
to the single bit level.
KMSAN keeps finding bugs. New ones, as well as the legacy ones.
- Yang Shi adds a userspace mechanism (madvise) to induce a collapse of
memory into THPs.
- Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to
support file/shmem-backed pages.
- userfaultfd updates from Axel Rasmussen
- zsmalloc cleanups from Alexey Romanov
- cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and
memory-failure
- Huang Ying adds enhancements to NUMA balancing memory tiering mode's
page promotion, with a new way of detecting hot pages.
- memcg updates from Shakeel Butt: charging optimizations and reduced

- Vishal Moola provides more folio conversions
- Zhang Yi removed ll_rw_block() :(
- migration enhancements from Peter Xu

git://git.kernel.org/pub/scm/linux/kernel/git/efi/efi
Pull EFI updates from Ard Biesheuvel:
"A bit more going on than usual in the EFI subsystem. The main driver
for this has been the introduction of the LoonArch architecture last
cycle, which inspired some cleanup and refactoring of the EFI code.
Another driver for EFI changes this cycle and in the future is
confidential compute.
The LoongArch architecture does not use either struct bootparams or DT
natively [yet], and so passing information between the EFI stub and
the core kernel using either of those is undesirable. And in general,
overloading DT has been a source of issues on arm64, so using DT for
this on new architectures is a to avoid for the time being (even if we
might converge on something DT based for non-x86 architectures in the
future). For this reason, in addition to the patch that enables EFI
boot for LoongArch, there are a number of refactoring patches applied
on top of which separate the DT bits from the generic EFI stub bits.
These changes are on a separate topich branch that has been shared
with the LoongArch maintainers, who will include it in their pull
request as well. This is not ideal, but the best way to manage the
conflicts without stalling LoongArch for another cycle.
Another development inspired by LoongArch is the newly added support
for EFI based decompressors. Instead of adding yet another
arch-specific incarnation of this pattern for LoongArch, we are
introducing an EFI app based on the existing EFI libstub
infrastructure that encapulates the decompression code we use on other
architectures, but in a way that is fully generic. This has been
developed and tested in collaboration with distro and systemd folks,
who are eager to start using this for systemd-boot and also for arm64
secure boot on Fedora. Note that the EFI zimage files this introduces
can also be decompressed by non-EFI bootloaders if needed, as the
image header describes the location of the payload inside the image,
and the type of compression that was used. (Note that Fedora's arm64
GRUB is buggy [0] so you'll need a recent version or switch to
systemd-boot in order to use this.)
Finally, we are adding TPM measurement of the kernel command line
provided by EFI. There is an oversight in the TCG spec which results
in a blind spot for command line arguments passed to loaded images,
which means that either the loader or the stub needs to take the
measurement. Given the combinatorial explosion I am anticipating when
it comes to firmware/bootloader stacks and firmware based attestation
protocols (SEV-SNP, TDX, DICE, DRTM), it is good to set a baseline now
when it comes to EFI measured boot, which is that the kernel measures
the initrd and command line. Intermediate loaders can measure
additional assets if needed, but with the baseline in place, we can
deploy measured boot in a meaningful way even if you boot into Linux
straight from the EFI firmware.
Summary:
- implement EFI boot support for LoongArch
- implement generic EFI compressed boot support for arm64, RISC-V and
LoongArch, none of which implement a decompressor today
- measure the kernel command line into the TPM if measured boot is in
effect
- refactor the EFI stub code in order to isolate DT dependencies for
architectures other than x86
- avoid calling SetVirtualAddressMap() on arm64 if the configured
size of the VA space guarantees that doing so is unnecessary
- move some ARM specific code out of the generic EFI source files
- unmap kernel code from the x86 mixed mode 1:1 page tables"

Pull ARM devicetree updates from Arnd Bergmann:
"Most of the changes fall into one of three categories: adding support
for additional devices on existing machines, cleaning up issues found
by the ongoing conversion to machine-readable bindings, and addressing
minor mistakes in the existing DT data.
Across SoC vendors, Qualcomm and Freescale stick out as getting the
most updates, which corresponds to their dominance in the mobile phone
and embedded industrial markets, respectively.
There are 636 non-merge changeset in this branch, which is a little
lower than most times, but more importantly we only add 36 machine
files, which is about half of what we had the past few releases.
Eight new SoCs are added, but all of them are variations of already
supported SoC families, and most of them come with one reference board
design from the SoC vendor:
- Mediatek MT8186 is a Chromebook/Tablet type SoC, similar to the
MT65xx series of phone SoCs, with two Cortex-A76 and six Cortex-A55
cores.
- TI AM62A is another member of the K3 family with Cortex-A53 cores,
this one is targetted at Video/Vision processing for industrial and
automotive applications.
- NXP i.MX8DXL is another chip for this market in the ever-growing
i.MX8 family, this one again with two Cortex-A35 cores.
- Renesas R-Car H3Ne-1.7G (R8A779MB) and R-Car V3H2 (R8A77980A) are
minor updates of R8A77951 and R8A77980, respectively.
- Qualcomm IPQ8064-v2.0, IPQ8062 and IPQ8065 are all variants of the
IPQ8064 chip, with minimally different features.
The AMD Pensando Elba and Apple M1 Ultra SoC support was getting close
this time, but in the end did not make the cut.
The new machines based on existing SoC support are fairly uneventful:
- Sony Xperia 1 IV is a fairly recent phone based on Qualcomm
Snapdragon 8 Gen 1.
- Three Samsung phones based on Snapdragon 410: Galaxy E5, E7 and
Grand Max. These are added for both 32-bit and 64-bit kernels, as
they originally shipped running 32-bit code.
- Two new servers using AST2600 BMCs: AMD DaytonaX and Ampere Mt.
Mitchell
- Three new machines based on Rockchips RK3399 and RK3566: Anberic
RG353P and RG503, Pine64 Pinephone Pro, Open AI Lab
- Multiple NXP i.MX6/i.MX8 based boards: Kontron SL/BL i.MX8MM OSM-S,
i.MX8MM Gateworks GW7904, MSC SM2S-IMX8PLUS SoM and carrier board
- Two development boards in the Microchip AT91 family: SAMA5D3-EDS
and lan966x-pcb8290.
- Minor variants of existing boards using Amlogic, Broadcom, Marvell,
Rockchips, Freescale Layerscape and Socionext Uniphier SoCs"

Commit ae626eb97376 ("ARM/dma-mapping: use dma-direct unconditionally")
caused a regression on the mvebu platform, wherein devices that are
dma-coherent are marked as dma-noncoherent, because although
mvebu_hwcc_notifier() after that commit still marks then as coherent,
the arm_coherent_dma_ops() function, which is called later, overwrites
this setting, since it is being called from drivers/of/device.c with
coherency parameter determined by of_dma_is_coherent(), and the
device-trees do not declare the 'dma-coherent' property.
Fix this by defaulting never clearing the dma_coherent flag in
arm_coherent_dma_ops().

Pull networking updates from Jakub Kicinski:
"Core:
- Introduce and use a single page frag cache for allocating small skb
heads, clawing back the 10-20% performance regression in UDP flood
test from previous fixes.
- Run packets which already went thru HW coalescing thru SW GRO. This
significantly improves TCP segment coalescing and simplifies
deployments as different workloads benefit from HW or SW GRO.
- Shrink the size of the base zero-copy send structure.
- Move TCP init under a new slow / sleepable version of DO_ONCE().
BPF:
- Add BPF-specific, any-context-safe memory allocator.
- Add helpers/kfuncs for PKCS#7 signature verification from BPF
programs.
- Define a new map type and related helpers for user space -> kernel
communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).
- Allow targeting BPF iterators to loop through resources of one
task/thread.
- Add ability to call selected destructive functions. Expose
crash_kexec() to allow BPF to trigger a kernel dump. Use
CAP_SYS_BOOT check on the loading process to judge permissions.
- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.
- Support struct arguments for trampoline based programs. Only
structs with size <= 16B and x86 are supported.
- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).
- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.
- Support accessing network tunnel metadata's flags.
- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.
- Add support for writing to Netfilter's nf_conn:mark.
Protocols:
- WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation
(MLO) work (802.11be, WiFi 7).
- vsock: improve support for SO_RCVLOWAT.
- SMC: support SO_REUSEPORT.
- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.
- IPSec: support collect metadata mode for xfrm interfaces.
- TCPv6: send consistent autoflowlabel in SYN_RECV state and RST
packets.
- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).
- MPTCP: support TCP_FASTOPEN_CONNECT.
- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.
- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.
- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.
- TLS: support the Korean ARIA-GCM crypto algorithm.
- Remove DECnet support.
Driver API:
- Allow selecting the conduit interface used by each port in DSA
switches, at runtime.
- Ethernet Power Sourcing Equipment and Power Device support.
- Add tc-taprio support for queueMaxSDU parameter, i.e. setting per
traffic class max frame size for time-based packet schedules.
- Support PHY rate matching - adapting between differing host-side
and link-side speeds.
- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.
- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.
- Require that flash component name used during update matches one of
the components for which version is reported by info_get().
- Remove "weight" argument from driver-facing NAPI API as much as
possible. It's one of those magic knobs which seemed like a good
idea at the time but is too indirect to use in practice.
- Support offload of TLS connections with 256 bit keys.

- Microchip KSZ9896 6-port Gigabit Ethernet Switch

When using the frame pointer unwinder, it was found that the stack trace
output of stack_trace_save() is incomplete if the stack contains
call_with_stack():

[0x8051191c] call_with_stack+0x1c/0x20
For the frame pointer unwinder, unwind_frame() checks stackframe::fp by
stackframe::sp. Since call_with_stack() switches the SP from one stack
to another, stackframe::fp and stackframe: :sp will point to different
stacks, so we can no longer check stackframe::fp by stackframe::sp. Skip
checking stackframe::fp at this point to avoid this problem.

Pull kernel hardening updates from Kees Cook:
"Most of the collected changes here are fixes across the tree for
various hardening features (details noted below).
The most notable new feature here is the addition of the memcpy()
overflow warning (under CONFIG_FORTIFY_SOURCE), which is the next step
on the path to killing the common class of "trivially detectable"
buffer overflow conditions (i.e. on arrays with sizes known at compile
time) that have resulted in many exploitable vulnerabilities over the
years (e.g. BleedingTooth).
This feature is expected to still have some undiscovered false
positives. It's been in -next for a full development cycle and all the
reported false positives have been fixed in their respective trees.
All the known-bad code patterns we could find with Coccinelle are also
either fixed in their respective trees or in flight.
The commit message in commit 54d9469bc515 ("fortify: Add run-time WARN
for cross-field memcpy()") for the feature has extensive details, but
I'll repeat here that this is a warning _only_, and is not intended to
actually block overflows (yet). The many patches fixing array sizes
and struct members have been landing for several years now, and we're
finally able to turn this on to find any remaining stragglers.
Summary:
Various fixes across several hardening areas:
- loadpin: Fix verity target enforcement (Matthias Kaehlcke).
- zero-call-used-regs: Add missing clobbers in paravirt (Bill
Wendling).
- CFI: clean up sparc function pointer type mismatches (Bart Van
Assche).
- Clang: Adjust compiler flag detection for various Clang changes
(Sami Tolvanen, Kees Cook).
- fortify: Fix warnings in arch-specific code in sh, ARM, and xen.
Improvements to existing features:
- testing: improve overflow KUnit test, introduce fortify KUnit test,
add more coverage to LKDTM tests (Bart Van Assche, Kees Cook).
- overflow: Relax overflow type checking for wider utility.
New features:
- string: Introduce strtomem() and strtomem_pad() to fill a gap in
strncpy() replacement needs.
- um: Enable FORTIFY_SOURCE support.
- fortify: Enable run-time struct member memcpy() overflow warning"

Kbuild puts the objects listed in head-y at the head of vmlinux.
Conventionally, we do this for head*.S, which contains the kernel entry
point.
A counter approach is to control the section order by the linker script.
Actually, the code marked as __HEAD goes into the ".head.text" section,
which is placed before the normal ".text" section.
I do not know if both of them are needed. From the build system
perspective, head-y is not mandatory. If you can achieve the proper code
placement by the linker script only, it would be cleaner.
I collected the current head-y objects into head-object-list.txt. It is
a whitelist. My hope is it will be reduced in the long run.

The objects placed at the head of vmlinux need special treatments:
- arch/$(SRCARCH)/Makefile adds them to head-y in order to place
them before other archives in the linker command line.
- arch/$(SRCARCH)/kernel/Makefile adds them to extra-y instead of
obj-y to avoid them going into built-in.a.
This commit gets rid of the latter.
Create vmlinux.a to collect all the objects that are unconditionally
linked to vmlinux. The objects listed in head-y are moved to the head
of vmlinux.a by using 'ar m'.
With this, arch/$(SRCARCH)/kernel/Makefile can consistently use obj-y
for builtin objects.
There is no *.o that is directly linked to vmlinux. Drop unneeded code
in scripts/clang-tools/gen_compile_commands.py.
$(AR) mPi needs 'T' to workaround the llvm-ar bug. The fix was suggested
by Nathan Chancellor [1].
