media: solo6x10: replace max(a, min(b, c)) by clamp(b, a, c)
This patch replaces max(a, min(b, c)) by clamp(b, a, c) in the solo6x10 driver. This improves the readability and more importantly, for the solo6x10-p2m.c file, this reduces on my system (x86-64, gcc 13): - the preprocessed size from 121 MiB to 4.5 MiB; - the build CPU time from 46.8 s to 1.6 s; - the build memory from 2786 MiB to 98MiB. In fine, this allows this relatively simple C file to be built on a 32-bit system.

execve: open the executable file before doing anything else
No point in allocating a new mm, counting arguments and environment variables etc if we're just going to return ENOENT. This patch does expose the fact that 'do_filp_open()' that execve() uses is still unnecessarily expensive in the failure case, because it allocates the 'struct file *' early, even if the path lookup (which is heavily optimized) fails. So that remains an unnecessary cost in the "no such executable" case, but it's a separate issue. Regardless, I do not want to do _both_ a filename_lookup() and a later do_filp_open() like the origin patch by Josh Triplett did in [1].

perf tools improvements and fixes for v6.8:
- Add Namhyung Kim as tools/perf/ co-maintainer, we're taking turns processing
patches, switching roles from perf-tools to perf-tools-next at each Linux
release.
Data profiling:
- Associate samples that identify loads and stores with data structures. This
uses events available on Intel, AMD and others and DWARF info:
# To get memory access samples in kernel for 1 second (on Intel)
$ perf mem record -a -K --ldlat=4 -- sleep 1
# Similar for the AMD (but it requires 6.3+ kernel for BPF filters)
$ perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' -- sleep 1
Then, amongst several modes of post processing, one can do things like:
$ perf report -s type,typeoff --hierarchy --group --stdio
...

This uses the existing annotate code, calling objdump to do the disassembly,
with improvements to avoid having this take too long, but longer term a
switch to a disassembler library, possibly reusing code in the kernel will
be pursued.
This is the initial implementation, please use it and report impressions and
bugs. Make sure the kernel-debuginfo packages match the running kernel. The
'perf report' phase for non short perf.data files may take a while.
There is a great article about it on LWN:

perf top/report:
- Don't ignore job control, allowing control+Z + bg to work.
- Add s390 raw data interpretation for PAI (Processor Activity Instrumentation)
counters.
perf archive:
- Add new option '--all' to pack perf.data with DSOs.
- Add new option '--unpack' to expand tarballs.
Initialization speedups:
- Lazily initialize zstd streams to save memory when not using it.
- Lazily allocate/size mmap event copy.
- Lazy load kernel symbols in 'perf record'.
- Be lazier in allocating lost samples buffer in 'perf record'.
- Don't synthesize BPF events when disabled via the command line (perf record --no-bpf-event).
Assorted improvements:
- Show note on AMD systems that the :p, :pp, :ppp and :P are all the same, as
IBS (Instruction Based Sampling) is used and it is inherentely precise, not
having levels of precision like in Intel systems.
- When 'cycles' isn't available, fall back to the "task-clock" event when not
system wide, not to 'cpu-clock'.
- Add --debug-file option to redirect debug output, e.g.:
$ perf --debug-file /tmp/perf.log record -v true
- Shrink 'struct map' to under one cacheline by avoiding function pointers for
selecting if addresses are identity or DSO relative, and using just a byte for
some boolean struct members.
- Resolve the arch specific strerrno just once to use in perf_env__arch_strerrno().
- Reduce memory for recording PERF_RECORD_LOST_SAMPLES event.
Assorted fixes:
- Fix the default 'perf top' usage on Intel hybrid systems, now it starts with
a browser showing the number of samples for Efficiency (cpu_atom/cycles/P) and
Performance (cpu_core/cycles/P). This behaviour is similar on ARM64, with its
respective set of big.LITTLE processors.
- Fix segfault on build_mem_topology() error path.
- Fix 'perf mem' error on hybrid related to availability of mem event in a PMU.
- Fix missing reference count gets (map, maps) in the db-export code.
- Avoid recursively taking env->bpf_progs.lock in the 'perf_env' code.
- Use the newly introduced maps__for_each_map() to add missing locking around
iteration of 'struct map' entries.
- Parse NOTE segments until the build id is found, don't stop on the first one,
ELF files may have several such NOTE segments.
- Remove 'egrep' usage, its deprecated, use 'grep -E' instead.
- Warn first about missing libelf, not libbpf, that depends on libelf.
- Use alternative to 'find ... -printf' as this isn't supported in busybox.
- Address python 3.6 DeprecationWarning for string scapes.
- Fix memory leak in uniq() in libsubcmd.
- Fix man page formatting for 'perf lock'
- Fix some spelling mistakes.
perf tests:
- Fail shell tests that needs some symbol in perf itself if it is stripped.
These tests check if a symbol is resolved, if some hot function is indeed
detected by profiling, etc.
- The 'perf test sigtrap' test is currently failing on PREEMPT_RT, skip it if
sleeping spinlocks are detected (using BTF) and point to the mailing list
discussion about it. This test is also being skipped on several architectures
(powerpc, s390x, arm and aarch64) due to other pending issues with intruction
breakpoints.
- Adjust test case perf record offcpu profiling tests for s390.
- Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest, addressing
issues caused by the fallback from cycles to task-clock done in this release.
- Fix mask for VG register in the user-regs test.
- Use shellcheck on 'perf test' shell scripts automatically to make sure changes
don't introduce things it flags as problematic.
- Add option to change objdump binary and allow it to be set via 'perf config'.

Pull perf tools updates from Arnaldo Carvalho de Melo:
"Add Namhyung Kim as tools/perf/ co-maintainer, we're taking turns
processing patches, switching roles from perf-tools to perf-tools-next
at each Linux release.
Data profiling:
- Associate samples that identify loads and stores with data
structures. This uses events available on Intel, AMD and others and
DWARF info:
# To get memory access samples in kernel for 1 second (on Intel)
$ perf mem record -a -K --ldlat=4 -- sleep 1
# Similar for the AMD (but it requires 6.3+ kernel for BPF filters)
$ perf mem record -a --filter 'mem_op == load || mem_op == store, ip > 0x8000000000000000' -- sleep 1
Then, amongst several modes of post processing, one can do things like:
$ perf report -s type,typeoff --hierarchy --group --stdio
...

This uses the existing annotate code, calling objdump to do the
disassembly, with improvements to avoid having this take too long,
but longer term a switch to a disassembler library, possibly
reusing code in the kernel will be pursued.
This is the initial implementation, please use it and report
impressions and bugs. Make sure the kernel-debuginfo packages match
the running kernel. The 'perf report' phase for non short perf.data
files may take a while.
There is a great article about it on LWN:
https://lwn.net/Articles/955709/ - "Data-type profiling for perf"
One last test I did while writing this text, on a AMD Ryzen 5950X,
using a distro kernel, while doing a simple 'find /' on an
otherwise idle system resulted in:

<SNIP>
perf top/report:
- Don't ignore job control, allowing control+Z + bg to work.
- Add s390 raw data interpretation for PAI (Processor Activity
Instrumentation) counters.
perf archive:
- Add new option '--all' to pack perf.data with DSOs.
- Add new option '--unpack' to expand tarballs.
Initialization speedups:
- Lazily initialize zstd streams to save memory when not using it.
- Lazily allocate/size mmap event copy.
- Lazy load kernel symbols in 'perf record'.
- Be lazier in allocating lost samples buffer in 'perf record'.
- Don't synthesize BPF events when disabled via the command line
(perf record --no-bpf-event).
Assorted improvements:
- Show note on AMD systems that the :p, :pp, :ppp and :P are all the
same, as IBS (Instruction Based Sampling) is used and it is
inherentely precise, not having levels of precision like in Intel
systems.
- When 'cycles' isn't available, fall back to the "task-clock" event
when not system wide, not to 'cpu-clock'.
- Add --debug-file option to redirect debug output, e.g.:
$ perf --debug-file /tmp/perf.log record -v true
- Shrink 'struct map' to under one cacheline by avoiding function
pointers for selecting if addresses are identity or DSO relative,
and using just a byte for some boolean struct members.
- Resolve the arch specific strerrno just once to use in
perf_env__arch_strerrno().
- Reduce memory for recording PERF_RECORD_LOST_SAMPLES event.
Assorted fixes:
- Fix the default 'perf top' usage on Intel hybrid systems, now it
starts with a browser showing the number of samples for Efficiency
(cpu_atom/cycles/P) and Performance (cpu_core/cycles/P). This
behaviour is similar on ARM64, with its respective set of
big.LITTLE processors.
- Fix segfault on build_mem_topology() error path.
- Fix 'perf mem' error on hybrid related to availability of mem event
in a PMU.
- Fix missing reference count gets (map, maps) in the db-export code.
- Avoid recursively taking env->bpf_progs.lock in the 'perf_env'
code.
- Use the newly introduced maps__for_each_map() to add missing
locking around iteration of 'struct map' entries.
- Parse NOTE segments until the build id is found, don't stop on the
first one, ELF files may have several such NOTE segments.
- Remove 'egrep' usage, its deprecated, use 'grep -E' instead.
- Warn first about missing libelf, not libbpf, that depends on
libelf.
- Use alternative to 'find ... -printf' as this isn't supported in
busybox.
- Address python 3.6 DeprecationWarning for string scapes.
- Fix memory leak in uniq() in libsubcmd.
- Fix man page formatting for 'perf lock'
- Fix some spelling mistakes.
perf tests:
- Fail shell tests that needs some symbol in perf itself if it is
stripped. These tests check if a symbol is resolved, if some hot
function is indeed detected by profiling, etc.
- The 'perf test sigtrap' test is currently failing on PREEMPT_RT,
skip it if sleeping spinlocks are detected (using BTF) and point to
the mailing list discussion about it. This test is also being
skipped on several architectures (powerpc, s390x, arm and aarch64)
due to other pending issues with intruction breakpoints.
- Adjust test case perf record offcpu profiling tests for s390.
- Fix 'Setup struct perf_event_attr' fails on s390 on z/VM guest,
addressing issues caused by the fallback from cycles to task-clock
done in this release.
- Fix mask for VG register in the user-regs test.
- Use shellcheck on 'perf test' shell scripts automatically to make
sure changes don't introduce things it flags as problematic.
- Add option to change objdump binary and allow it to be set via
'perf config'.
- Add basic 'perf script', 'perf list --json" and 'perf diff' tests.
- Basic branch counter support.
- Make DSO tests a suite rather than individual.
- Remove atomics from test_loop to avoid test failures.
- Fix call chain match on powerpc for the record+probe_libc_inet_pton
test.
- Improve Intel hybrid tests.

Merge tag 'vfs-6.8.netfs' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner:
"This extends the netfs helper library that network filesystems can use
to replace their own implementations. Both afs and 9p are ported. cifs
is ready as well but the patches are way bigger and will be routed
separately once this is merged. That will remove lots of code as well.
The overal goal is to get high-level I/O and knowledge of the page
cache and ouf of the filesystem drivers. This includes knowledge about
the existence of pages and folios
The pull request converts afs and 9p. This removes about 800 lines of
code from afs and 300 from 9p. For 9p it is now possible to do writes
in larger than a page chunks. Additionally, multipage folio support
can be turned on for 9p. Separate patches exist for cifs removing
another 2000+ lines. I've included detailed information in the
individual pulls I took.
Summary:
- Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O
calls to prevent these from happening at the same time.
- Support for direct and unbuffered I/O.
- Support for write-through caching in the page cache.
- O_*SYNC and RWF_*SYNC writes use write-through rather than writing
to the page cache and then flushing afterwards.
- Support for write-streaming.
- Support for write grouping.
- Skip reads for which the server could only return zeros or EOF.
- The fscache module is now part of the netfs library and the
corresponding maintainer entry is updated.
- Some helpers from the fscache subsystem are renamed to mark them as
belonging to the netfs library.
- Follow-up fixes for the netfs library.
- Follow-up fixes for the 9p conversion"

of: Stop circularly including of_device.h and of_platform.h
The DT of_device.h and of_platform.h headers date back to the separate of_platform_bus_type before it was merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. The headers also include platform_device.h and of.h. The result was lots of drivers relied on these implicit includes. Now the entire tree has been fixed over the last couple of cycles to explicitly include the necessary headers instead of relying on of_device.h and/or of_platform.h implicit includes, so the implicit and circular includes can finally be removed.

Use preferred device_get_match_data() instead of of_match_device() to get the driver match data. With this, adjust the includes to explicitly include the correct headers. Error checking for matching and match data was not necessary as matching is always successful if we're already in probe and the match tables always have data pointers.

Changes since last update:
- Fix a "BUG: kernel NULL pointer dereference" issue due to
inconsistent on-disk indices of compressed inodes against
per-sb `available_compr_algs` generated by Syzkaller;
- Don't use certain unnecessary folio_*() helpers if the folio
type (page cache) is known.

This cycle, I2C removes the currently unused CLASS_DDC support
(controllers set the flag, but there is no client to use it). Also, CLASS_SPD support gets simplified to prepare removal in the future. Class based instantiation is not recommended these days anyhow. Furthermore, I2C core now creates a debugfs directory per I2C adapter. Current bus driver users were converted to use it. Then, there are also quite some driver updates. Standing out are patches for the wmt-driver which is refactored to support more variants. This is the rebased pull request where a large series for the designware driver was dropped. -----BEGIN PGP SIGNATURE----- iQJDBAABCgAtFiEEOZGx6rniZ1Gk92RdFA3kzBSgKbYFAmWph0UPHHdzYUBrZXJu ZWwub3JnAAoJEBQN5MwUoCm2kbIQAJotSmX0mM+nNPReYCMMiloxoxUwgpiErNwY WDrYQSezthAJ1LDsGOEeLcE4f4I+UcUHBO1BoERtOZg3cGtE0Ii5N845sp100S9O ktyaKS5utoErymThWFFrnZX60/8yKXUMzZmNzy96560gPcxbFyyyVhKfBSPzK9T+ O8CGu7GRNqgWHlvH3yqGeCbreWYrYVSrluEpBu6807cp3zDxrU+autOnsewm5+md ka3DdqrbxJSblYK8fJKESAUgkRmZgYKbgl0iiCuqX+ib6I4OA3Z68ny7dl0fY3Ws vwt7d88SaBKDdJmUZyb/sm4aJsW69GN+ECZolxrn4TIw45k4tes2s6Ma5+TV3E9h Fd1RuqduFEqQ7cj31UPe2x8rgj5Fo5nbjCWxdZv+/3zF8+cHwi8iwkp2PScsPCsa fmCdehUE5DrgobsRNANe6XJzxY5wp2VNpGEWKeaQz2Z0/d9T1YFS7a8aewvhXoPC isZboi6GQh2XoE8UgGJa29VUuaIkUW513DwCGw8mz1yKN+kHGcsRXXjkjaZoQn3U MMvh/zkI2Hpy/m2R8PWeIq5XhLJvmlZ19JJzUHJIjXh9Fn9EVtXhlUleh6mzMfeM n8NOg7Eukep2sBgmaufkUKz2Jtogs59YDSXZEvqJjIkPM2Wi0hA18Qj+pilES1ff 3ckk3mxY =8D3Q -----END PGP SIGNATURE----- Merge tag 'i2c-for-6.8-rc1-rebased' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux Pull i2c updates from Wolfram Sang: "This removes the currently unused CLASS_DDC support (controllers set the flag, but there is no client to use it).

Merge tag 'gpio-fixes-for-v6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio fixes from Bartosz Golaszewski:
"Apart from some regular driver fixes there's a relatively big revert
of the locking changes that were introduced to GPIOLIB in this merge
window.
This is because it turned out that some legacy GPIO interfaces - that
need to translate a number from the global GPIO numberspace to the
address of the relevant descriptor, thus running a GPIO device lookup
and taking the GPIO device list lock - are still used in old code from
atomic context resulting in "scheduling while atomic" errors.
I'll try to make the read-only part of the list access entirely
lockless using SRCU but this will take some time so let's go back to
the old global spinlock for now.
Summary:
- revert the changes aiming to use a read-write semaphore to protect
the list of GPIO devices due to calls to legacy API taking that
lock from atomic context in old code
- fix inverted logic in DEFINE_FREE() for GPIO device references
- check the return value of bgpio_init() in gpio-mlxbf3
- fix node address in the DT bindings example for gpio-xilinx
- fix signedness bug in gpio-rtd
- fix kernel-doc warnings in gpio-en7523"

pwm changes for 6.8, take 2
The first commit fixes a duplicate cleanup in an error path introduced in pwm/for-6.8-rc1~13. The second cares for an out-of-bounds access. In practise it doesn't happen---otherwise someone would have noticed since v5.17-rc1 I guess---because the device tree binding for the two drivers using of_pwm_single_xlate() only have args->args_count == 1. A device-tree that doesn't conform to the respective bindings could trigger that easily however. The third and last one corrects the request callback of the jz4740 pwm driver which used dev_err_probe() long after .probe() completed. This is conceptually wrong because dev_err_probe() might call device_set_deferred_probe_reason() which is nonsensical after the driver is bound. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEP4GsaTp6HlmJrf7Tj4D7WH0S/k4FAmWo3dwACgkQj4D7WH0S /k5L3Qf8Db1uwUEGFXjjMIS82djW6u8rAEu1bEVf0yqhFKB3zo/PO4b1bfTHvKGo SwSflvZ2UB+bcby1yIZTP1yUbDH1O3WFfxgYwdUR715us/iMCV5sYvuNagi0Fp8O edR1Ntr/CmaU5VeDyml7ZUIHj7oZ50hd1dvvEugvKQKEVvW8yHBR2OEuqI38cIyK ItsQPrN9ld7PXzE0UFWMJpi3lbo+Q4KEYbx0yzBmBGogLXi+nRCIGtMB5KzdUSvf K4mQPHDmUyHsviXyjXcywst7sL1ebUcI3FicvCf4by/Sek5jZQGtLoyRS0m4FkRw V/TQMiLhU5iKr84wPQUvw6ZYmcXxog== =BP0a -----END PGP SIGNATURE----- Merge tag 'pwm/for-6.8-2' of gitolite.kernel.org:pub/scm/linux/kernel/git/ukleinek/linux Pull pwm fixes from Uwe Kleine-König: - fix a duplicate cleanup in an error path introduced in this merge window - fix an out-of-bounds access In practise it doesn't happen - otherwise someone would have noticed since v5.17-rc1 I guess - because the device tree binding for the two drivers using of_pwm_single_xlate() only have args->args_count == 1.
