Pull io_uring fixes from Jens Axboe:
- Stop setting PF_NO_SETAFFINITY on io-wq workers.
This has been reported in the past as it confuses some applications,
as some of their threads will fail with -1/EINVAL if attempted
affinitized. Most recent report was on cpusets, where enabling that
with io-wq workers active will fail.
Just deal with the mask changing by checking when a worker times out,
and then exit if we have no work pending.
- Fix an issue with passthrough support where we don't properly check
if the file type has pollable uring_cmd support.
- Fix a reported W=1 warning on a variable being set and unused. Add a
special helper for iterating these lists that doesn't save the
previous list element, if that iterator never ends up using it.

Pull perf tools fixes from Arnaldo Carvalho de Melo:
- Add Adrian Hunter to MAINTAINERS as a perf tools reviewer
- Sync various tools/ copies of kernel headers with the kernel sources,
this time trying to avoid first merging with upstream to then update
but instead copy from upstream so that a merge is avoided and the end
result after merging this pull request is the one expected,
tools/perf/check-headers.sh (mostly) happy, less warnings while
building tools/perf/
- Fix counting when initial delay configured by setting
perf_attr.enable_on_exec when starting workloads from the perf
command line
- Don't avoid emitting a PERF_RECORD_MMAP2 in 'perf inject
--buildid-all' when that record comes with a build-id, otherwise we
end up not being able to resolve symbols
- Don't use comma as the CSV output separator the "stat+csv_output"
test, as comma can appear on some tests as a modifier for an event,
use @ instead, ditto for the JSON linter test
- The offcpu test was looking for some bits being set on
task_struct->prev_state without masking other bits not important for
this specific 'perf test', fix it

The same strapping initialization issue that happened on NBIO 7.5.1
appears to be happening on NBIO 7.3.0.
Apply the same fix to 7.3.0 as well.
Note: This workaround relies upon the integrated GPU being enabled
in BIOS. If the integrated GPU is disabled in BIOS a different
workaround will be required.

We're currently using stop_machine() to update ftrace & kprobes, which
means that the thread that takes text_mutex during may not be the same
as the thread that eventually patches the code. This isn't actually a
race because the lock is still held (preventing any other concurrent
accesses) and there is only one thread running during stop_machine(),
but it does trigger a lockdep failure.
This patch just elides the lockdep check during stop_machine.

The i2cdev_{at,de}tach_adapter() callbacks are used for two purposes:
1. As notifier callbacks, when (un)registering I2C adapters created or
destroyed after i2c_dev_init(),
2. As bus iterator callbacks, for registering already existing
adapters from i2c_dev_init(), and for cleanup.
Unfortunately both use cases expect different return values: the former
expects NOTIFY_* return codes, while the latter expects zero or error
codes, and aborts in case of error.
Hence in case 2, as soon as i2cdev_{at,de}tach_adapter() returns
(non-zero) NOTIFY_OK, the bus iterator aborts. This causes (a) only the
first already existing adapter to be registered, leading to missing
/dev/i2c-* entries, and (b) a failure to unregister all but the first
I2C adapter during cleanup.
Fix this by introducing separate callbacks for the bus iterator,
wrapping the notifier functions, and always returning succes.
Any errors inside these callback functions are unlikely to happen, and
are fatal anyway.

Now that .probe() was changed not to get the id parameter, drivers can
be converted back to that with the eventual goal to drop .probe_new().
Implement that for the i2c drivers that are part of the i2c core.

Commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back
type") introduced a new probe callback to convert i2c init routines to
not take an i2c_device_id parameter. Now that all in-tree drivers are
converted to the temporary .probe_new() callback, .probe() can be
modified to match the desired prototype.
Now that .probe() and .probe_new() have the same semantic, they can be
defined as members of an anonymous union to save some memory and
simplify the core code a bit.

msm-fixes for v6.3-rc2
- Fix for possible invalid ptr free in submit ioctl syncobj cleanup path.
- Synchronize GMU removal in driver teardown path
- a5xx preemption fixes
- Fix runpm imbalance at unbind
- DPU hw catalog fixes:
- set DPU_MDP_PERIPH_0_REMOVED for sc8280xp as this is another chipset
where the PERIPH_0 block of registers is not there
- fix the DPU features supported in QCM2290 by comparing it with the
downstream device tree
- fix the length of registers in the sc7180_ctl from 0xe4 to 0x1dc
- fix the max mixer line width for sm6115 and qcm2290 chipsets in the
DPU catalog
- fix the scaler version on sm8550, sc8280xp, sm8450, sm8250, sm8350
and sm6115. This was incorrectly populated on the SW version of the
scaler library and not the scaler HW version
- Drop dim layer support for msm8998 as its not indicated to be
supported in the downstream DTSI
- fix the DPU_CLK_CTRL bits for msm 8998 sspp blocks
- Use DPU_CLK_CTRL_DMA* prefix instead of DPU_CLK_CTRL_CURSOR*
for all chipsets for the DMA sspp blocks
- fix the ping-pong block base address for sc7280 in the DPU HW catalog
- Fix stack corruption issue in the dpu_hw_ctl_setup_blendstage() function
as it was causing a negative left shift by protecting against an invalid
index
- Clear the DSPP reservations in dpu_rm_release(). This was missed out and
as as result the DSPP was not released from the resource manager global
state.

If io_uring.o is built with W=1, it triggers a warning:
io_uring/io_uring.c: In function ‘__io_submit_flush_completions’:
io_uring/io_uring.c:1502:40: warning: variable ‘prev’ set but not used [-Wunused-but-set-variable]
1502 | struct io_wq_work_node *node, *prev;

which is due to the wq_list_for_each() iterator always keeping a 'prev'
variable. Most users need this to remove an entry from a list, for
example, but __io_submit_flush_completions() never does that.
Add a basic helper that doesn't track prev instead, and use that in
that function.

Let's revert commit 12724ba38992 ("erofs: fix kvcalloc() misuse with
__GFP_NOFAIL") since kvmalloc() already supports __GFP_NOFAIL in commit
a421ef303008 ("mm: allow !GFP_KERNEL allocations for kvmalloc"). So
the original fix was wrong.
Actually there was some issue as [1] discussed, so before that mm fix
is landed, the warn could still happen but applying this commit first
will cause less.

Now that the same hardware that the r8188eu driver supported is
supported by the real wireless driver rtl8xxxu, the r8188eu driver can
be deleted.
Also the rtl8xxxu driver supports way more devices, and is a fraction of
the overall size, making this a much better overall solution.
Thanks to the r8188eu developers and maintainers and reviewers over the
years, your work allowed Linux users to use their hardware before the
real driver was implemented properly.

Lorenzo points out that the generic CLI is broken for the netdev
family. When I added the support for documentation of enums
(and sparse enums) the client script was not updated.
It expects the values in enum to be a list of names,
now it can also be a dict (YAML object).
