Pull ARM SoC devicetree updates from Arnd Bergmann:
"As usual, this is the bulk of the updates for the SoC tree, adding
more devices to existing files, addressing issues from ever improving
automated checking, and fixing minor issues.
The most interesting bits as usual are the new platforms. All the
newly supported SoCs belong into existing families this time:
- Qualcomm gets support for two newly announced platforms, both of
which can now work in production environments: the SDX65 5G modem
that can run a minimal Linux on its Cortex-A7 core, and the
Snapdragon 8 Gen 1, their latest high-end phone SoC.
- Renesas adds support for R-Car S4-8, the most recent automotive
Server/Communication SoC.
- TI adds support for J721s2, a new automotive SoC in the K3 family.
- Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
generation following their popular MT76xx series. Only basic
support is added for now.
- NXP i.MX8 ULP8 is a new low-power variant of the widespread i.MX8
series.
- TI SPEAr320s is a minor variant of the old SPEAr320 SoC that we
have supported for a long time.
New boards with the existing SoCs include
- Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
- AT91/SAMA5 based evaluation board
- NXP gains twenty new development and industrial boards for their
i.MX and Layerscape SoCs
- Intel IXP4xx now supports the final two machines in device tree
that were previously only supported in old style board files.
- Mediatek MT6589 is used in the Fairphone FP1 phone from 2013, while
MT8183 is used in the Acer Chromebook 314.
- Qualcomm gains support for the reference machines using the two new
SoCs, plus a number of Chromebook variants and phones based on the
Snapdragon 7c, 845 and 888 SoCs, including various Sony Xperia
devices and the Microsoft Surface Duo 2.
- ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
- Tegra now boots various older Android devices based on 32-bit chips
out of the box, including a number of ASUS Transformer tablets.
There is also a new Jetson AGX Orin developer kit.
- Apple support adds the missing device trees for all the remaining
M1 Macbook and iMac variants, though not yet the M1 Pro/Max
versions.
- Allwinner now supports another version of the Tanix TX6 set-top box
based on the H6 SoC.
- Broadcom gains support for the Netgear RAXE500 Wireless router
based on BCM4908"

Pull ARM SoC driver updates from Arnd Bergmann:
"There are cleanups and minor bugfixes across several SoC specific
drivers, for Qualcomm, Samsung, NXP i.MX, AT91, Tegra, Keystone,
Renesas, ZynqMP
Noteworthy new features are:
- The op-tee firmware driver gains support for asynchronous
notifications from secure-world firmware.
- Qualcomm platforms gain support for new SoC types in various
drivers: power domain, cache controller, RPM sleep, soc-info
- Samsung SoC drivers gain support for new SoCs in ChipID and PMU, as
well as a new USIv2 driver that handles various types of serial
communiction (uart, i2c, spi)
- Renesas adds support for R-Car S4-8 (R8A779F0) in multiple drivers,
as well as memory controller support for RZ/G2L (R9A07G044).

Since irq request is the last thing in the driver probe, it happens
later than the input device registration. This means that there is a
small time window where if the open method is called the driver will
attempt to enable not yet available irq.
Fix that by moving the irq request before the input device registration.

This largely reverts commit 5a7b95fb993ec399c8a685552aa6a8fc995c40bd. It
breaks suspend with AMD GPUs, and we couldn't incrementally fix it. So,
let's remove the code and go back to the drawing board. We keep the
header extension to not break drivers already populating the regulator.
We expect to re-add the code handling it soon.

This reverts commit 08efcb4a638d260ef7fcbae64ecf7ceceb3f1841.
This breaks the build as it will prefer using libbpf-devel header files,
even when not using LIBBPF_DYNAMIC=1, breaking the build.
This was detected on OpenSuSE Tumbleweed with libtraceevent-devel 1.3.0,
as described by Jiri Slaby:
=======================================================================
It breaks build with LIBTRACEEVENT_DYNAMIC and version 1.3.0:
> util/debug.c: In function ‘perf_debug_option’:
> util/debug.c:243:17: error: implicit declaration of function
‘tep_set_loglevel’ [-Werror=implicit-function-declaration]

function)
> 247 | tep_set_loglevel(TEP_LOG_ALL);

It is because the gcc's command line looks like:
gcc
...
-I/home/abuild/rpmbuild/BUILD/tools/lib/
...
-DLIBTRACEEVENT_VERSION=65790
...
=======================================================================
The proper way to fix this is more involved and so not suitable for this
late in the 5.16-rc stage.

sense to
When running 'perf trace' with an BPF object like:
# perf trace -e openat,tools/perf/examples/bpf/hello.c
the event parsing eventually calls llvm__get_kbuild_opts() that runs a
script and that ends up with SIGCHLD delivered to the 'perf trace'
handler, which assumes the workload process is done and quits 'perf
trace'.
Move the SIGCHLD handler setup directly to trace__run(), where the event
is parsed and the object is already compiled.

cgroup process migration permission checks are performed at write time as
whether a given operation is allowed or not is dependent on the content of
the write - the PID. This currently uses current's cgroup namespace which is
a potential security weakness as it may allow scenarios where a less
privileged process tricks a more privileged one into writing into a fd that
it created.
This patch makes cgroup remember the cgroup namespace at the time of open
and uses it for migration permission checks instad of current's. Note that
this only applies to cgroup2 as cgroup1 doesn't have namespace support.
This also fixes a use-after-free bug on cgroupns reported in
https://lore.kernel.org/r/00000000000048c15c05d0083397@google.com
Note that backporting this fix also requires the preceding patch.

of->priv is currently used by each interface file implementation to store
private information. This patch collects the current two private data usages
into struct cgroup_file_ctx which is allocated and freed by the common path.
This allows generic private data which applies to multiple files, which will
be used to in the following patch.
Note that cgroup_procs iterator is now embedded as procs.iter in the new
cgroup_file_ctx so that it doesn't need to be allocated and freed
separately.
v2: union dropped from cgroup_file_ctx and the procs iterator is embedded in
cgroup_file_ctx as suggested by Linus.
v3: Michal pointed out that cgroup1's procs pidlist uses of->priv too.
Converted. Didn't change to embedded allocation as cgroup1 pidlists get
stored for caching.

osnoise tracer on ppc64le is triggering osnoise_taint() for negative
duration in get_int_safe_duration() called from
trace_sched_switch_callback()->thread_exit().
The problem though is that the check for a valid trace_percpu_buffer is
incorrect in get_trace_buf(). The check is being done after calculating
the pointer for the current cpu, rather than on the main percpu pointer.
Fix the check to be against trace_percpu_buffer.
