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.

coccinelle: device_attr_show: simplify patch case
Replacing the final expression argument by ... allows the format string to have multiple arguments. It also has the advantage of allowing the change to be recognized as a change in a single statement, thus avoiding adding unneeded braces. Signed-off-by: Julia Lawall <Julia.Lawall@inria.fr> |

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:
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

<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.
Vendor event files (JSON):
powerpc:
- Update datasource event name to fix duplicate events on IBM's Power10.
- Add PVN for HX-C2000 CPU with Power8 Architecture.
Intel:
- Alderlake/rocketlake metric fixes.
- Update emeraldrapids events to v1.02.
- Update icelakex events to v1.23.
- Update sapphirerapids events to v1.17.
- Add skx, clx, icx and spr upi bandwidth metric.
AMD:
- Add Zen 4 memory controller events.
RISC-V:
- Add StarFive Dubhe-80 and Dubhe-90 JSON files.
https://www.starfivetech.com/en/site/cpu-u
- Add T-HEAD C9xx JSON file.
https://github.com/riscv-software-src/opensbi/blob/master/docs/platform/thead-c9xx.md
ARM64:
- Remove UTF-8 characters from cmn.json, that were causing build failure in some
distros.
- Add core PMU events and metrics for Ampere One X.
- Rename Ampere One's BPU_FLUSH_MEM_FAULT to GPC_FLUSH_MEM_FAULT
libperf:
- Rename several perf_cpu_map constructor names to clarify what they really do.
- Ditto for some other methods, coping with some issues in their semantics,
like perf_cpu_map__empty() -> perf_cpu_map__has_any_cpu_or_is_empty().
- Document perf_cpu_map__nr()'s behavior
perf stat:
- Exit if parse groups fails.
- Combine the -A/--no-aggr and --no-merge options.
- Fix help message for --metric-no-threshold option.
Hardware tracing:
ARM64 CoreSight:
- Bump minimum OpenCSD version to ensure a bugfix is present.
- Add 'T' itrace option for timestamp trace
- Set start vm addr of exectable file to 0 and don't ignore first sample on the
arm-cs-trace-disasm.py 'perf script'.

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:

- 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.
Vendor event files (JSON):
powerpc:
- Update datasource event name to fix duplicate events on IBM's
Power10.

ARM64:
- Remove UTF-8 characters from cmn.json, that were causing build
failure in some distros.
- Add core PMU events and metrics for Ampere One X.
- Rename Ampere One's BPU_FLUSH_MEM_FAULT to GPC_FLUSH_MEM_FAULT
libperf:
- Rename several perf_cpu_map constructor names to clarify what they
really do.
- Ditto for some other methods, coping with some issues in their
semantics, like perf_cpu_map__empty() ->
perf_cpu_map__has_any_cpu_or_is_empty().
- Document perf_cpu_map__nr()'s behavior
perf stat:
- Exit if parse groups fails.
- Combine the -A/--no-aggr and --no-merge options.
- Fix help message for --metric-no-threshold option.
Hardware tracing:

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"

cifs: update iface_last_update on each query-and-update
iface_last_update was an unused field when it was introduced.
Later, when we had periodic update of server interface list,
this field was used regularly to decide when to update next.
However, with the new logic of updating the interfaces, it
becomes crucial that this field be updated whenever
parse_server_interfaces runs successfully.
This change updates this field when either the server does
not support query of interfaces; so that we do not query
the interfaces repeatedly. It also updates the field when
the function reaches the end.

cifs: handle servers that still advertise multichannel after disabling
Some servers like Azure SMB servers always advertise multichannel capability in server capabilities list. Such servers return error STATUS_NOT_IMPLEMENTED for ioctl calls to query server interfaces, and expect clients to consider that as a sign that they do not support multichannel. We already handled this at mount time. Soon after the tree connect, we query server interfaces. And when server returned STATUS_NOT_IMPLEMENTED, we kept interface list as empty. When cifs_try_adding_channels gets called, it would not find any interfaces, so will not add channels. For the case where an active multichannel mount exists, and multichannel is disabled by such a server, this change will now allow the client to disable secondary channels on the mount. It will check the return status of query server interfaces call soon after a tree reconnect. If the return status is EOPNOTSUPP, then instead of the check to add more channels, we'll disable the secondary channels instead. For better code reuse, this change also moves the common code for disabling multichannel to a helper function.

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.

net: can: Use device_get_match_data()
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.

Maximum number of channels for USB-DMAC as per the driver is 1-99 so use
u8 instead of unsigned int/int for DMAC channel indexing and make the
pdev_irqname string long enough to avoid the warning.
While at it use scnprintf() instead of sprintf() to make the code more
robust.
