Move the declarations to an appropriate header where they can be seen
by the caller and callee, and make sure the headers are included where
needed.

[ Fixed ftrace_return_to_handler() to handle CONFIG_HAVE_FUNCTION_GRAPH_RETVAL case ]

The ftrace samples need per-architecture trampoline implementations
to save and restore argument registers around the calls to
my_direct_func* and to restore polluted registers (eg: x30).
These samples also include <asm/asm-offsets.h> which, on arm64, is not
necessary and redefines previously defined macros (resulting in
warnings) so these includes are guarded by !CONFIG_ARM64.

Pull tracing fixes from Steven Rostedt:
- Fix bad git merge of #endif in arm64 code
A merge of the arm64 tree caused #endif to go into the wrong place
- Fix crash on lseek of write access to tracefs/error_log
Opening error_log as write only, and then doing an lseek() causes a
kernel panic, because the lseek() handle expects a "seq_file" to
exist (which is not done on write only opens). Use tracing_lseek()
that tests for this instead of calling the default seq lseek handler.
- Check for negative instead of -E2BIG for error on strscpy() returns
Instead of testing for -E2BIG from strscpy(), to be more robust,
check for less than zero, which will make sure it catches any error
that strscpy() may someday return.

It appears that a merge conflict ended up hiding a newly added constant

Pull tracing updates from Steven Rostedt:
- Add new feature to have function graph tracer record the return
value. Adds a new option: funcgraph-retval ; when set, will show the
return value of a function in the function graph tracer.
- Also add the option: funcgraph-retval-hex where if it is not set, and
the return value is an error code, then it will return the decimal of
the error code, otherwise it still reports the hex value.
- Add the file /sys/kernel/tracing/osnoise/per_cpu/cpu<cpu>/timerlat_fd
That when a application opens it, it becomes the task that the timer
lat tracer traces. The application can also read this file to find
out how it's being interrupted.
- Add the file /sys/kernel/tracing/available_filter_functions_addrs
that works just the same as available_filter_functions but also shows
the addresses of the functions like kallsyms, except that it gives
the address of where the fentry/mcount jump/nop is. This is used by
BPF to make it easier to attach BPF programs to ftrace hooks.

Pull new ARM SoC support from Arnd Bergmann:
"There are two new SoC families this time, and both appear fairly
similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are

embedded market, and they mark the first 64-bit product in a widely
used family of 32-bit Arm MCUs and SoCs.
The way into the kernel is completely different here: The team at ST
has a long history of working upstream with their STM32MP1 and other
SoCs, and they produced a complete port to arm64 together with the
initial announcement. Nuvoton also has multiple SoC product lines with
current or previous upstream support, but those are maintained by
third parties and are unrelated. The patch series from Nuvoton's Jacky
Huang had to go through many revisisions to get to this point and is
still missing a few drivers including the serial port for the moment.

Pull ARM SoC devicetree updates from Arnd Bergmann:
"The biggest change this time is for the 32-bit devicetree files, which
are all moved to a new location, using separate subdirectories for
each SoC vendor, following the same scheme that is used on arm64, mips
and riscv. This has been discussed for many years, but so far we never
did this as there was a plan to move the files out of the kernel
entirely, which has never happened.
The impact of this will be that all external patches no longer apply,
and anything depending on the location of the dtb files in the build
directory will have to change. The installed files after 'make
dtbs_install' keep the current location.
There are six added SoCs here that are largely variants of previously
added chips. Two other chips are added in a separate branch along with
their device drivers.
- The Samsung Exynos 4212 makes its return after the Samsung Galaxy
Express phone is addded at last. The SoC support was originally
added in 2012 but removed again in 2017 as it was unused at the
time.
- Amlogic C3 is a Cortex-A35 based smart IP camera chip
- Qualcomm MSM8939 (Snapdragon 615) is a more featureful variant of
the still common MSM8916 (Snapdragon 410) phone chip that has been
supported for a long time.
- Qualcomm SC8180x (Snapdragon 8cx) is one of their earlier high-end
laptop chips, used in the Lenovo Flex 5G, which is added along with
the reference board.
- Qualcomm SDX75 is the latest generation modem chip that is used as
a peripherial in phones but can also run a standalone Linux. Unlike
the prior 32-bit SDX65 and SDX55, this now has a 64-bit Cortex-A55.
- Alibaba T-Head TH1520 is a quad-core RISC-V chip based on the
Xuantie C910 core, a step up from all previously added rv64 chips.
All of the above come with reference board implementations, those
included there are 39 new board files, but only five more 32-bit this
time, probably a new low:
- Marantec Maveo board based on dhcor imx6ull module
- Endian 4i Edge 200, based on the armv5 Marvell Kirkwood chip
- Epson Moverio BT-200 AR glasses based on TI OMAP4
- PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM
- ICnova ADB4006 board based on Allwinner A20
On the 64-bit side, there are also fewer addded machines than we had
in the recent releases:
- Three boards based on NXP i.MX8: Emtop SoM & Baseboard, NXP i.MX8MM
EVKB board and i.MX8MP based Gateworks Venice gw7905-2x device.
- NVIDIA IGX Orin and Jetson Orin Nano boards, both based on tegra234
- Qualcomm gains support for 6 reference boards on various members of
their IPQ networking SoC series, as well as the Sony Xperia M4 Aqua
phone, the Acer Aspire 1 laptop, and the Fxtec Pro1X board on top
of the various reference platforms for their new chips.
- Rockchips support for several newer boards: Indiedroid Nova
(rk3588), Edgeble Neural Compute Module 6B (rk3588), FriendlyARM
NanoPi R2C Plus (rk3328), Anbernic RG353PS (rk3566), Lunzn
Fastrhino R66S/R68S (rk3568)
- TI K3/AM625 based PHYTEC phyBOARD-Lyra-AM625 board and Toradex
Verdin family with AM62 COM, carrier and dev boards
Other changes to existing boards contain the usual minor improvements
along with
- continued updates to clean up dts files based on dtc warnings and
binding checks, in particular cache properties and node names
- support for devicetree overlays on at91, bcm283x
- significant additions to existing SoC support on mediatek,
qualcomm, ti k3 family, starfive jh71xx, NXP i.MX6 and i.MX8, ST
STM32MP1

The FFR is a predicate register which can vary between 16 and 256 bits
in size depending upon the configured vector length. When saving the
SVE state in streaming SVE mode, the FFR register is inaccessible and
so commit 9f5848665788 ("arm64/sve: Make access to FFR optional") simply
clears the FFR field of the in-memory context structure. Unfortunately,
it achieves this using an unconditional 8-byte store and so if the SME
vector length is anything other than 64 bytes in size we will either
fail to clear the entire field or, worse, we will corrupt memory
immediately following the structure. This has led to intermittent kfence
splats in CI [1] and can trigger kmalloc Redzone corruption messages
when running the 'fp-stress' kselftest:
| =============================================================================
| BUG kmalloc-1k (Not tainted): kmalloc Redzone overwritten
| -----------------------------------------------------------------------------
|
| 0xffff000809bf1e22-0xffff000809bf1e27 @offset=7714. First byte 0x0 instead of 0xcc

| __kmalloc+0x8c/0xcc
| do_sme_acc+0x9c/0x220
| ...
Replace the 8-byte store with a store of a predicate register which has
been zero-initialised with PFALSE, ensuring that the entire field is
cleared in memory.

This modifies our user mode stack expansion code to always take the
mmap_lock for writing before modifying the VM layout.
It's actually something we always technically should have done, but
because we didn't strictly need it, we were being lazy ("opportunistic"
sounds so much better, doesn't it?) about things, and had this hack in
place where we would extend the stack vma in-place without doing the
proper locking.
And it worked fine. We just needed to change vm_start (or, in the case
of grow-up stacks, vm_end) and together with some special ad-hoc locking
using the anon_vma lock and the mm->page_table_lock, it all was fairly
straightforward.
That is, it was all fine until Ruihan Li pointed out that now that the
vma layout uses the maple tree code, we *really* don't just change
vm_start and vm_end any more, and the locking really is broken. Oops.
It's not actually all _that_ horrible to fix this once and for all, and
do proper locking, but it's a bit painful. We have basically three
different cases of stack expansion, and they all work just a bit
differently:
- the common and obvious case is the page fault handling. It's actually
fairly simple and straightforward, except for the fact that we have
something like 24 different versions of it, and you end up in a maze
of twisty little passages, all alike.
- the simplest case is the execve() code that creates a new stack.
There are no real locking concerns because it's all in a private new
VM that hasn't been exposed to anybody, but lockdep still can end up
unhappy if you get it wrong.
- and finally, we have GUP and page pinning, which shouldn't really be
expanding the stack in the first place, but in addition to execve()
we also use it for ptrace(). And debuggers do want to possibly access
memory under the stack pointer and thus need to be able to expand the
stack as a special case.
None of these cases are exactly complicated, but the page fault case in
particular is just repeated slightly differently many many times. And
ia64 in particular has a fairly complicated situation where you can have
both a regular grow-down stack _and_ a special grow-up stack for the
register backing store.
So to make this slightly more manageable, the bulk of this series is to
first create a helper function for the most common page fault case, and
convert all the straightforward architectures to it.
Thus the new 'lock_mm_and_find_vma()' helper function, which ends up
being used by x86, arm, powerpc, mips, riscv, alpha, arc, csky, hexagon,
loongarch, nios2, sh, sparc32, and xtensa. So we not only convert more
than half the architectures, we now have more shared code and avoid some
of those twisty little passages.
And largely due to this common helper function, the full diffstat of
this series ends up deleting more lines than it adds.
That still leaves eight architectures (ia64, m68k, microblaze, openrisc,
parisc, s390, sparc64 and um) that end up doing 'expand_stack()'
manually because they are doing something slightly different from the
normal pattern. Along with the couple of special cases in execve() and
GUP.
So there's a couple of patches that first create 'locked' helper
versions of the stack expansion functions, so that there's a obvious
path forward in the conversion. The execve() case is then actually
pretty simple, and is a nice cleanup from our old "grow-up stackls are
special, because at execve time even they grow down".
The #ifdef CONFIG_STACK_GROWSUP in that code just goes away, because
it's just more straightforward to write out the stack expansion there
manually, instead od having get_user_pages_remote() do it for us in some
situations but not others and have to worry about locking rules for GUP.
And the final step is then to just convert the remaining odd cases to a
new world order where 'expand_stack()' is called with the mmap_lock held
for reading, but where it might drop it and upgrade it to a write, only
to return with it held for reading (in the success case) or with it
completely dropped (in the failure case).
In the process, we remove all the stack expansion from GUP (where
dropping the lock wouldn't be ok without special rules anyway), and add
it in manually to __access_remote_vm() for ptrace().
Thanks to Adrian Glaubitz and Frank Scheiner who tested the ia64 cases.
Everything else here felt pretty straightforward, but the ia64 rules for
stack expansion are really quite odd and very different from everything
else. Also thanks to Vegard Nossum who caught me getting one of those
odd conditions entirely the wrong way around.
Anyway, I think I want to actually move all the stack expansion code to
a whole new file of its own, rather than have it split up between
mm/mmap.c and mm/memory.c, but since this will have to be backported to
the initial maple tree vma introduction anyway, I tried to keep the
patches _fairly_ minimal.
Also, while I don't think it's valid to expand the stack from GUP, the
final patch in here is a "warn if some crazy GUP user wants to try to
expand the stack" patch. That one will be reverted before the final
release, but it's left to catch any odd cases during the merge window
and release candidates.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking changes from Jakub Kicinski:
"WiFi 7 and sendpage changes are the biggest pieces of work for this
release. The latter will definitely require fixes but I think that we
got it to a reasonable point.
Core:
- Rework the sendpage & splice implementations
Instead of feeding data into sockets page by page extend sendmsg
handlers to support taking a reference on the data, controlled by a
new flag called MSG_SPLICE_PAGES
Rework the handling of unexpected-end-of-file to invoke an
additional callback instead of trying to predict what the right
combination of MORE/NOTLAST flags is
Remove the MSG_SENDPAGE_NOTLAST flag completely
- Implement SCM_PIDFD, a new type of CMSG type analogous to
SCM_CREDENTIALS, but it contains pidfd instead of plain pid
- Enable socket busy polling with CONFIG_RT
- Improve reliability and efficiency of reporting for ref_tracker
- Auto-generate a user space C library for various Netlink families
Protocols:
- Allow TCP to shrink the advertised window when necessary, prevent
sk_rcvbuf auto-tuning from growing the window all the way up to
tcp_rmem[2]
- Use per-VMA locking for "page-flipping" TCP receive zerocopy
- Prepare TCP for device-to-device data transfers, by making sure
that payloads are always attached to skbs as page frags
- Make the backoff time for the first N TCP SYN retransmissions
linear. Exponential backoff is unnecessarily conservative
- Create a new MPTCP getsockopt to retrieve all info
(MPTCP_FULL_INFO)
- Avoid waking up applications using TLS sockets until we have a full
record
- Allow using kernel memory for protocol ioctl callbacks, paving the
way to issuing ioctls over io_uring
- Add nolocalbypass option to VxLAN, forcing packets to be fully
encapsulated even if they are destined for a local IP address
- Make TCPv4 use consistent hash in TIME_WAIT and SYN_RECV. Ensure
in-kernel ECMP implementation (e.g. Open vSwitch) select the same
link for all packets. Support L4 symmetric hashing in Open vSwitch
- PPPoE: make number of hash bits configurable
- Allow DNS to be overwritten by DHCPACK in the in-kernel DHCP client
(ipconfig)
- Add layer 2 miss indication and filtering, allowing higher layers
(e.g. ACL filters) to make forwarding decisions based on whether
packet matched forwarding state in lower devices (bridge)
- Support matching on Connectivity Fault Management (CFM) packets
- Hide the "link becomes ready" IPv6 messages by demoting their
printk level to debug
- HSR: don't enable promiscuous mode if device offloads the proto
- Support active scanning in IEEE 802.15.4
- Continue work on Multi-Link Operation for WiFi 7
BPF:
- Add precision propagation for subprogs and callbacks. This allows
maintaining verification efficiency when subprograms are used, or
in fact passing the verifier at all for complex programs,
especially those using open-coded iterators
- Improve BPF's {g,s}setsockopt() length handling. Previously BPF
assumed the length is always equal to the amount of written data.
But some protos allow passing a NULL buffer to discover what the
output buffer *should* be, without writing anything
- Accept dynptr memory as memory arguments passed to helpers
- Add routing table ID to bpf_fib_lookup BPF helper
- Support O_PATH FDs in BPF_OBJ_PIN and BPF_OBJ_GET commands
- Drop bpf_capable() check in BPF_MAP_FREEZE command (used to mark
maps as read-only)
- Show target_{obj,btf}_id in tracing link fdinfo
- Addition of several new kfuncs (most of the names are
self-explanatory):
- Add a set of new dynptr kfuncs: bpf_dynptr_adjust(),
bpf_dynptr_is_null(), bpf_dynptr_is_rdonly(), bpf_dynptr_size()
and bpf_dynptr_clone().
- bpf_task_under_cgroup()
- bpf_sock_destroy() - force closing sockets
- bpf_cpumask_first_and(), rework bpf_cpumask_any*() kfuncs
Netfilter:
- Relax set/map validation checks in nf_tables. Allow checking
presence of an entry in a map without using the value
- Increase ip_vs_conn_tab_bits range for 64BIT builds
- Allow updating size of a set
- Improve NAT tuple selection when connection is closing
Driver API:
- Integrate netdev with LED subsystem, to allow configuring HW
"offloaded" blinking of LEDs based on link state and activity
(i.e. packets coming in and out)
- Support configuring rate selection pins of SFP modules
- Factor Clause 73 auto-negotiation code out of the drivers, provide
common helper routines
- Add more fool-proof helpers for managing lifetime of MDIO devices
associated with the PCS layer
- Allow drivers to report advanced statistics related to Time Aware
scheduler offload (taprio)
- Allow opting out of VF statistics in link dump, to allow more VFs
to fit into the message
- Split devlink instance and devlink port operations

Pull locking updates from Ingo Molnar:
- Introduce cmpxchg128() -- aka. the demise of cmpxchg_double()
The cmpxchg128() family of functions is basically & functionally the
same as cmpxchg_double(), but with a saner interface.
Instead of a 6-parameter horror that forced u128 - u64/u64-halves
layout details on the interface and exposed users to complexity,
fragility & bugs, use a natural 3-parameter interface with u128
types.
- Restructure the generated atomic headers, and add kerneldoc comments
for all of the generic atomic{,64,_long}_t operations.
The generated definitions are much cleaner now, and come with
documentation.
- Implement lock_set_cmp_fn() on lockdep, for defining an ordering when
taking multiple locks of the same type.
This gets rid of one use of lockdep_set_novalidate_class() in the
bcache code.
- Fix raw_cpu_generic_try_cmpxchg() bug due to an unintended variable
shadowing generating garbage code on Clang on certain ARM builds.

Pull scheduler updates from Ingo Molnar:
"Scheduler SMP load-balancer improvements:
- Avoid unnecessary migrations within SMT domains on hybrid systems.
Problem:
On hybrid CPU systems, (processors with a mixture of
higher-frequency SMT cores and lower-frequency non-SMT cores),
under the old code lower-priority CPUs pulled tasks from the
higher-priority cores if more than one SMT sibling was busy -
resulting in many unnecessary task migrations.
Solution:
The new code improves the load balancer to recognize SMT cores
with more than one busy sibling and allows lower-priority CPUs
to pull tasks, which avoids superfluous migrations and lets
lower-priority cores inspect all SMT siblings for the busiest
queue.
- Implement the 'runnable boosting' feature in the EAS balancer:
consider CPU contention in frequency, EAS max util & load-balance
busiest CPU selection.
This improves CPU utilization for certain workloads, while leaves
other key workloads unchanged.
Scheduler infrastructure improvements:
- Rewrite the scheduler topology setup code by consolidating it into
the build_sched_topology() helper function and building it
dynamically on the fly.
- Resolve the local_clock() vs. noinstr complications by rewriting
the code: provide separate sched_clock_noinstr() and
local_clock_noinstr() functions to be used in instrumentation code,
and make sure it is all instrumentation-safe.
Fixes:
- Fix a kthread_park() race with wait_woken()
- Fix misc wait_task_inactive() bugs unearthed by the -rt merge:
- Fix UP PREEMPT bug by unifying the SMP and UP implementations
- Fix task_struct::saved_state handling
- Fix various rq clock update bugs, unearthed by turning on the rq
clock debugging code.
- Fix the PSI WINDOW_MIN_US trigger limit, which was easy to trigger
by creating enough cgroups, by removing the warnign and restricting
window size triggers to PSI file write-permission or
CAP_SYS_RESOURCE.
- Propagate SMT flags in the topology when removing degenerate domain
- Fix grub_reclaim() calculation bug in the deadline scheduler code
- Avoid resetting the min update period when it is unnecessary, in
psi_trigger_destroy().
- Don't balance a task to its current running CPU in load_balance(),
which was possible on certain NUMA topologies with overlapping
groups.
- Fix the sched-debug printing of rq->nr_uninterruptible
Cleanups:
- Address various -Wmissing-prototype warnings, as a preparation to
(maybe) enable this warning in the future.
- Remove unused code
- Mark more functions __init
- Fix shadow-variable warnings"

Pull SMP updates from Thomas Gleixner:
"A large update for SMP management:
- Parallel CPU bringup
The reason why people are interested in parallel bringup is to
shorten the (kexec) reboot time of cloud servers to reduce the
downtime of the VM tenants.
The current fully serialized bringup does the following per AP:
1) Prepare callbacks (allocate, intialize, create threads)
2) Kick the AP alive (e.g. INIT/SIPI on x86)
3) Wait for the AP to report alive state
4) Let the AP continue through the atomic bringup
5) Let the AP run the threaded bringup to full online state
There are two significant delays:
#3 The time for an AP to report alive state in start_secondary()
on x86 has been measured in the range between 350us and 3.5ms
depending on vendor and CPU type, BIOS microcode size etc.
#4 The atomic bringup does the microcode update. This has been
measured to take up to ~8ms on the primary threads depending
on the microcode patch size to apply.
On a two socket SKL server with 56 cores (112 threads) the boot CPU
spends on current mainline about 800ms busy waiting for the APs to
come up and apply microcode. That's more than 80% of the actual
onlining procedure.
This can be reduced significantly by splitting the bringup
mechanism into two parts:
1) Run the prepare callbacks and kick the AP alive for each AP
which needs to be brought up.
The APs wake up, do their firmware initialization and run the
low level kernel startup code including microcode loading in
parallel up to the first synchronization point. (#1 and #2
above)
2) Run the rest of the bringup code strictly serialized per CPU
(#3 - #5 above) as it's done today.
Parallelizing that stage of the CPU bringup might be possible
in theory, but it's questionable whether required surgery
would be justified for a pretty small gain.
If the system is large enough the first AP is already waiting at
the first synchronization point when the boot CPU finished the
wake-up of the last AP. That reduces the AP bringup time on that
SKL from ~800ms to ~80ms, i.e. by a factor ~10x.
The actual gain varies wildly depending on the system, CPU,
microcode patch size and other factors. There are some
opportunities to reduce the overhead further, but that needs some
deep surgery in the x86 CPU bringup code.
For now this is only enabled on x86, but the core functionality
obviously works for all SMP capable architectures.
- Enhancements for SMP function call tracing so it is possible to
locate the scheduling and the actual execution points. That allows
to measure IPI delivery time precisely"

With the advent on scope-based resource management it comes really
tedious to abide by the contraints of -Wdeclaration-after-statement.
It will still be recommeneded to place declarations at the start of a

|
|
Currently when restoring the TPIDR2 signal context we set the new value
from the signal frame in the thread data structure but not the register,
following the pattern for the rest of the data we are restoring. This does
not work in the case of TPIDR2, the register always has the value for the
current task. This means that either we return to userspace and ignore the
new value or we context switch and save the register value on top of the
newly restored value.
Load the value from the signal context into the register instead.

Just like for sc7180 devices using the Chrome bootflow (AKA trogdor
and IDP), sc7280 devices using the Chrome bootflow also need their
firmware marked dma-coherent. On sc7280 this wasn't causing WiFi to
fail to startup, since WiFi works differently there. However, on
sc7280 devices we were still getting the message at bootup after
commit 7bd6680b47fa ("Revert "Revert "arm64: dma: Drop cache
invalidation from arch_dma_prep_coherent()"""):
qcom_scm firmware:scm: Assign memory protection call failed -22
qcom_rmtfs_mem 9c900000.memory: assign memory failed
qcom_rmtfs_mem: probe of 9c900000.memory failed with error -22
We should mark SCM properly just like we did for trogdor.

Trogdor devices use firmware backed by TF-A instead of Qualcomm's
normal TZ. On TF-A we end up mapping memory as cacheable.
Specifically, you can see in Trogdor's TF-A code [1] in
qti_sip_mem_assign() that we call qti_mmap_add_dynamic_region() with
MT_RO_DATA. This translates down to MT_MEMORY instead of
MT_NON_CACHEABLE or MT_DEVICE. Apparently Qualcomm's normal TZ
implementation maps the memory as non-cacheable.
Let's add the "dma-coherent" attribute to the SCM for trogdor.
Adding "dma-coherent" like this fixes WiFi on sc7180-trogdor
devices. WiFi was broken as of commit 7bd6680b47fa ("Revert "Revert
"arm64: dma: Drop cache invalidation from
arch_dma_prep_coherent()"""). Specifically at bootup we'd get:
qcom_scm firmware:scm: Assign memory protection call failed -22
qcom_rmtfs_mem 94600000.memory: assign memory failed
qcom_rmtfs_mem: probe of 94600000.memory failed with error -22
From discussion on the mailing lists [2] and over IRC [3], it was
determined that we should always have been tagging the SCM as
dma-coherent on trogdor but that the old "invalidate" happened to make
things work most of the time. Tagging it properly like this is a much
more robust solution.

sc7180-idp is, for most intents and purposes, a trogdor device.
Specifically, sc7180-idp is designed to run the same style of firmware
as trogdor devices. This can be seen from the fact that IDP has the
same "Reserved memory changes" in its device tree that trogdor has.
Recently it was realized that we need to mark SCM as dma-coherent to
match what trogdor's style of firmware (based on TF-A) does [1]. That
means we need this dma-coherent tag on IDP as well.
Without this, on newer versions of Linux, specifically those with
commit 7bd6680b47fa ("Revert "Revert "arm64: dma: Drop cache
invalidation from arch_dma_prep_coherent()"""), WiFi will fail to
work. At bootup you'll see:

KVM_ARM_VCPU_POWER_OFF is as bit index, _not_ a literal bitmask.
Nonetheless, commit e3c1c0cae31e ("KVM: arm64: Relax invariance
of KVM_ARM_VCPU_POWER_OFF") started using it that way, meaning that
powering off a vCPU with the KVM_ARM_VCPU_INIT ioctl is completely
broken.

Now we specify the minimal version of GCC as 5.1 and Clang/LLVM as 11.0.0
in Documentation/process/changes.rst, __CHAR_BIT__ and __SIZEOF_LONG__ are
usable, it is probably fine to unify the definition of __BITS_PER_LONG as
(__CHAR_BIT__ * __SIZEOF_LONG__) in asm-generic uapi bitsperlong.h.
In order to keep safe and avoid regression, only unify uapi bitsperlong.h
for some archs such as arm64, riscv and loongarch which are using newer
toolchains that have the definitions of __CHAR_BIT__ and __SIZEOF_LONG__.

The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.
There's no change to dtbs_install as the flat structure is maintained on
install.
The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)
The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.

When patching kernel alternatives, we need to be careful not to execute
kernel code which is itself subject to patching. In general, if code is
executed after the instructions in memory have been patched but prior to
the cache maintenance and barriers completing, it could lead to
UNPREDICTABLE results.
As our regular cache maintenance routines are patched with alternatives,
we have a clean_dcache_range_nopatch() function which is *intended* to
avoid patchable code and therefore supposed to be safe in the middle of
patching alternatives. Unfortunately, it's not marked as 'noinstr', and
so can be instrumented with patchable code.
Additionally, it calls read_sanitised_ftr_reg() (which may be
instrumented with patchable code) to find the sanitized value of
CTR_EL0.DminLine, and is therefore not safe to call during patching.
Luckily, since commit:
675b0563d6b26aa9 ("arm64: cpufeature: expose arm64_ftr_reg struct for CTR_EL0")
... we can read the sanitised CTR_EL0 value directly, and avoid the call
to read_sanitised_ftr_reg().
This patch marks clean_dcache_range_nopatch() as noinstr, and has it
read the sanitized CTR_EL0 value directly, avoiding the issues above.
As a bonus, this is also an optimization. As read_sanitised_ftr_reg()
performs a binary search to find the CTR_EL0 value, reading the value
directly avoids this binary search per applied alternative, avoiding
some unnecessary work.

During hibernation or restoration, freeze_secondary_cpus
checks num_online_cpus via BUG_ON, and the subsequent
save_processor_state also does the checking with WARN_ON.
In the case of CONFIG_PM_SLEEP_SMP=n, freeze_secondary_cpus
is not defined, but the sole possible condition to disable
CONFIG_PM_SLEEP_SMP is !SMP where num_online_cpus is always 1.
We also don't have to check it in save_processor_state.
So remove the unnecessary checking in save_processor_state.
