git://git.kernel.org/pub/scm/linux/kernel/git/joro/iommu
Pull iommu updates from Joerg Roedel:
- Consolidate iommu_map/unmap functions.
There have been blocking and atomic variants so far, but that was
problematic as this approach does not scale with required new
variants which just differ in the GFP flags used. So Jason
consolidated this back into single functions that take a GFP
parameter.
- Retire the detach_dev() call-back in iommu_ops

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH:
"Here is the large set of driver core changes for 6.3-rc1.
There's a lot of changes this development cycle, most of the work
falls into two different categories:
- fw_devlink fixes and updates. This has gone through numerous review
cycles and lots of review and testing by lots of different devices.
Hopefully all should be good now, and Saravana will be keeping a
watch for any potential regression on odd embedded systems.
- driver core changes to work to make struct bus_type able to be
moved into read-only memory (i.e. const) The recent work with Rust
has pointed out a number of areas in the driver core where we are
passing around and working with structures that really do not have
to be dynamic at all, and they should be able to be read-only
making things safer overall. This is the contuation of that work
(started last release with kobject changes) in moving struct
bus_type to be constant. We didn't quite make it for this release,
but the remaining patches will be finished up for the release after
this one, but the groundwork has been laid for this effort.
Other than that we have in here:
- debugfs memory leak fixes in some subsystems
- error path cleanups and fixes for some never-able-to-be-hit
codepaths.
- cacheinfo rework and fixes
- Other tiny fixes, full details are in the shortlog
All of these have been in linux-next for a while with no reported
problems"

that there's a pending report that has a fix that is queued up - Linus ]

Pull staging driver updates from Greg KH:
"Here is the "boring" staging driver update for 6.3-rc1.
Nothing major in here at all, it's just lots of tiny code cleanups to
bring some of the staging drivers more in line with the real portion
of the kernel (apis and coding style.) Overall we remove more lines of
code than we add, always a nice result.

Fix the cifs_writepages_region() to just jump over members of the batch
that have been cleaned up rather than counting them as skipped.
Unlike the other "skip_write" cases, this situation happens even for
WB_SYNC_ALL, simply because the page has either been cleaned by somebody
else, or was truncated.
So in this case we're not "skipping" the write, we simply no longer need
any write at all, so it's very different from the other skip_write cases.
And we definitely shouldn't stop writing the rest just because of too
many of these cases (or because we want to be rescheduled).

Each probe has an instance of process_fetch_insn respectively,
but they have something in common.
This patch aims to extract the common part into
process_common_fetch_insn which can be shared by each probe,
and they only need to focus on their special cases.

There are 6 function definitions in trace_probe_tmpl.h, they are:
1, fetch_store_strlen
2, fetch_store_string
3, fetch_store_strlen_user
4, fetch_store_string_user
5, probe_mem_read
6, probe_mem_read_user
Every C file which includes trace_probe_tmpl.h has to implement them,
otherwise it gets warnings and errors. However, some of them are identical,
like kprobe and eprobe, as a result, there is a lot redundant code in those
2 files.
This patch would like to provide default behaviors for those functions
which kprobe and eprobe can share by just including trace_probe_kernel.h
with trace_probe_tmpl.h together.
It removes redundant code, increases readability, and more importantly,

print_probe_args is currently inplemented in trace_probe_tmpl.h and
included by *probes, as a result, each probe has an identical copy.
This patch will move it to trace_probe.c as an new API, each probe
calls it to print their args in trace file.

Pull modules updates from Luis Chamberlain:
"Nothing exciting at all for modules for v6.3.
The biggest change is just the change of INSTALL_MOD_DIR from "extra"
to "updates" which I found lingered for ages for no good reason while
testing the CXL mock driver [0].
The CXL mock driver has no kconfig integration and requires building
an external module... and re-building the *rest* of the production
drivers. This mock driver when loaded but not the production ones will
crash.
All this can obviously be fixed by integrating kconfig semantics into
such test module, however that's not desirable by the maintainer, and
so sensible defaults must be used to ensure a default "make
modules_install" will suffice for most distros which do not have a
file like /etc/depmod.d/dist.conf with something like `search updates
extra built-in`.
Since most distros rely on kmod and since its inception the "updates"
directory is always in the search path it makes more sense to use that
than the "extra" which only *some* RH based systems rely on.
All this stuff has been on linux-next for a while"

Pull perf tools updates from Arnaldo Carvalho de Melo:
"Miscellaneous:
- Add Ian Rogers to MAINTAINERS as a perf tools reviewer.
- Add support for retire latency feature (pipeline stall of a
instruction compared to the previous one, in cycles) present on
some Intel processors.
- Add 'perf c2c' report option to show false sharing with adjacent
cachelines, to be used in machines with cacheline prefetching,
where accesses to a cacheline brings the next one too.
- Skip 'perf test bpf' when the required kernel-debuginfo package
isn't installed.
- Avoid d3-flame-graph package dependency in 'perf script flamegraph',
making this feature more generally available.
- Add JSON metric events to present CPI stall cycles in Power10.
- Assorted improvements/refactorings on the JSON metrics parsing
code.
perf lock contention:
- Add -o/--lock-owner option:
$ sudo ./perf lock contention -abo -- ./perf bench sched pipe
# Running 'sched/pipe' benchmark:
# Executed 1000000 pipe operations between two processes
Total time: 4.766 [sec]
4.766540 usecs/op

1 8.25 us 8.25 us 8.25 us 1583144 sched-pipe
1 2.03 us 2.03 us 2.03 us 5068 chrome
The owner is unknown in most cases. Filtering only for the
mutex locks, it will more likely get the owners.
- -S/--callstack-filter is to limit display entries having the given
string in the callstack:
$ sudo ./perf lock contention -abv -S net sleep 1
...

Please note that to have the -b option (BPF) working above one has
to build with BUILD_BPF_SKEL=1.
- Add more 'perf test' entries to test these new features.
perf script:
- Add 'cgroup' field for 'perf script' output:
$ perf record --all-cgroups -- true
$ perf script -F comm,pid,cgroup
true 337112 /user.slice/user-657345.slice/[email protected]/...
true 337112 /user.slice/user-657345.slice/[email protected]/...
true 337112 /user.slice/user-657345.slice/[email protected]/...
true 337112 /user.slice/user-657345.slice/[email protected]/...
- Add support for showing branch speculation information in 'perf
script' and in the 'perf report' raw dump (-D).
perf record:
- Fix 'perf record' segfault with --overwrite and --max-size.
perf test/bench:
- Switch basic BPF filtering test to use syscall tracepoint to avoid
the variable number of probes inserted when using the previous
probe point (do_epoll_wait) that happens on different CPU
architectures.
- Fix DWARF unwind test by adding non-inline to expected function in
a backtrace.
- Use 'grep -c' where the longer form 'grep | wc -l' was being used.
- Add getpid and execve benchmarks to 'perf bench syscall'.
Intel PT:
- Add support for synthesizing "cycle" events from Intel PT traces as
we support "instruction" events when Intel PT CYC packets are
available. This enables much more accurate profiles than when using
the regular 'perf record -e cycles' (the default) when the workload
lasts for very short periods (<10ms).
- .plt symbol handling improvements, better handling IBT (in the past
MPX) done in the context of decoding Intel PT processor traces,
IFUNC symbols on x86_64, static executables, understanding .plt.got
symbols on x86_64.
- Add a 'perf test' to test symbol resolution, part of the .plt
improvements series, this tests things like symbol size in contexts
where only the symbol start is available (kallsyms), etc.
- Better handle auxtrace/Intel PT data when using pipe mode (perf
record sleep 1|perf report).
- Fix symbol lookup with kcore with multiple segments match stext,
getting the symbol resolution to just show DSOs as unknown.
ARM:
- Timestamp improvements for ARM64 systems with ETMv4 (Embedded Trace
Macrocell v4).
- Ensure ARM64 CoreSight timestamps don't go backwards.
- Document that ARM64 SPE (Statistical Profiling Extension) is used
with 'perf c2c/mem'.
- Add raw decoding for ARM64 SPEv1.2 previous branch address.
- Update neoverse-n2-v2 ARM vendor events (JSON tables): topdown L1,
TLB, cache, branch, PE utilization and instruction mix metrics.
- Update decoder code for OpenCSD version 1.4, on ARM64 systems.
- Fix command line auto-complete of CPU events on aarch64.
Build:
- Fix 'perf probe' and 'perf test' when libtraceevent isn't linked,
as several tests use tracepoints, those should be skipped.
- More fallout fixes for the removal of tools/lib/traceevent/.
- Fix build error when linking with libpfm"

Pull tracing fix from Steven Rostedt:
"Fix race that causes a warning of corrupt ring buffer
With the change that allows to read the "trace" file without disabling
writing to the ring buffer, there was an integrity check of the ring
buffer in the iterator read code, that expected the ring buffer to be
write disabled. This caused the integrity check to trigger when stress
reading the "trace" file while writing was happening.
The integrity check is a bit aggressive (and has never triggered in
practice). Change it so that it checks just the integrity of the
linked pages without clearing the flags inside the pointers. This
removes the warning that was being triggered"
[ Heh. This was supposed to have gone in last week before the 6.2
release, but Steven forgot to actually add me to the participants of
the pull request, so here it is, a week later - Linus ]
