iio: bu27034: Add a read only HARDWAREGAIN
The ROHM BU27034 light sensor has two data channels for measuring
different frequencies of light. The result from these channels is
combined into Lux value while the raw channel values are reported via
intensity channels.
Both of the intensity channels have adjustable gain setting which
impacts the scale of the raw channels. Eg, doubling the gain will double
the values read from the raw channels, which halves the scale value. The
integration time can also be set for the sensor. This does also have an
impact to the scale of the intensity channels because increasing the
integration time will also increase the values reported via the raw
channels.
Impact of integration time to the scale and the fact that the scale value
does not start from '1', can make it hard for a human reader to compute the
gain values based on the scale.
Add read-only HARDWAREGAIN to help debugging.

dt-bindings: iio: BU27034 => BU27034ANUC
The BU27034NUC was cancelled before it entered mass production. It was
replaced by a new variant BU27034ANUC (note, added 'A'). The new
variant gained a few significant changes, like removal of the 3.rd data
channel and dropping some of the gain settings. This means that, from
software point of view these ICs are incompatible. Lux calculation based
on the data from the sensors needs to be done differently, and on the
BU27034ANUC the channel 3 data is missing. Also, the gain setting
differencies matter.
Unfortunately, the identification register was not changed so there is no
safe way for the software to distinguish the variants.
According to the ROHM HQ engineers, the old BU27034NUC should not be
encountered in the wild. Hence it makes sense to remove the support for
the old BU27034NUC and add support for the new BU27034ANUC. Change the
compatible in order to not load the incompatible old driver for new sensor
(or, if someone had the old sensor, the new driver for it).
Drop the compatible for old sensor which should not be in the wild and
add a new compatible for the new model with accurate model suffix
'anuc'. Rename the file to match the new compatible.

iio: chemical: bme680: Refactorize reading functions
The reading of the pressure and humidity value, requires an update of the
t_fine variable which happens by reading the temperature value.
So the bme680_read_{press/humid}() functions of the above sensors are
internally calling the equivalent bme680_read_temp() function in order to
update the t_fine value. By just looking at the code this relation is a
bit hidden and is not easy to understand why those channels are not
independent.
This commit tries to clear these thing a bit by splitting the
bme680_{read/compensate}_{temp/press/humid}() to the following:
i. bme680_read_{temp/press/humid}_adc(): read the raw value from the
sensor.
ii. bme680_calc_t_fine(): calculate the t_fine variable.
iii. bme680_get_t_fine(): get the t_fine variable.
iv. bme680_compensate_{temp/press/humid}(): compensate the adc values and
return the calculated value.

If there's only one possible scale, there's no way to change the Vref
select in the device so avoid reading the register in ad9467_get_scale().
In this case, it makes no sense to provide the .read_available()
callback nor allowing for writing the scale attribute.
Note this is in preparation for supporting a new device that only has
one possible scale.

This is in preparation for supporting new parts with subtle differences

Note that with the new test_points variable, we also add a new
calib_map_size to 'struct ad9467_state' so we know our map size
depending on how many test points we have and if we can run the
calibration in the inverted state or not.

iio: adc: ad9467: support multiple channels calibration
The calibration process mixes the support for calibrating multiple
channels with only having one channel. Some paths do have 'num_channels'
into account while others don't.
As of now, the driver only supports devices with one channel so the
above is not really a problem. That said, we'll add support for devices
with more than one channel, hence let's properly make the calibration
process to work with it.

iio: core: add accessors 'masklength'
'masklength' is supposed to be an IIO private member. However, drivers
(often in trigger handlers) need to access it to iterate over the
enabled channels for example (there are other reasons). Hence, a couple
of new accessors are being added:
* iio_for_each_active_channel() - Iterates over the active channels;
* iio_get_masklength() - Get length of the channels mask.
The goal of these new accessors is to annotate 'masklength' as private
as soon as all drivers accessing it are converted to use the new
helpers.

minmax: simplify and clarify min_t()/max_t() implementation
This simplifies the min_t() and max_t() macros by no longer making them
work in the context of a C constant expression.
That means that you can no longer use them for static initializers or
for array sizes in type definitions, but there were only a couple of
such uses, and all of them were converted (famous last words) to use
MIN_T/MAX_T instead.

minmax: add a few more MIN_T/MAX_T users
Commit
3a7e02c040b1 ("minmax: avoid overly complicated constant
expressions in VM code") added the simpler MIN_T/MAX_T macros in order
to avoid some excessive expansion from the rather complicated regular
min/max macros.
The complexity of those macros stems from two issues:
(a) trying to use them in situations that require a C constant
expression (in static initializers and for array sizes)
(b) the type sanity checking
and MIN_T/MAX_T avoids both of these issues.
Now, in the whole (long) discussion about all this, it was pointed out
that the whole type sanity checking is entirely unnecessary for
min_t/max_t which get a fixed type that the comparison is done in.
But that still leaves min_t/max_t unnecessarily complicated due to
worries about the C constant expression case.
However, it turns out that there really aren't very many cases that use
min_t/max_t for this, and we can just force-convert those.
This does exactly that.
Which in turn will then allow for much simpler implementations of
min_t()/max_t(). All the usual "macros in all upper case will evaluate
the arguments multiple times" rules apply.
We should do all the same things for the regular min/max() vs MIN/MAX()
cases, but that has the added complexity of various drivers defining
their own local versions of MIN/MAX, so that needs another level of
fixes first.

kbuild: Fix '-S -c' in x86 stack protector scripts
After a recent change in clang to stop consuming all instances of '-S'
and '-c' [1], the stack protector scripts break due to the kernel's use
of -Werror=unused-command-line-argument to catch cases where flags are
not being properly consumed by the compiler driver:
$ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument
clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument]
This results in CONFIG_STACKPROTECTOR getting disabled because
CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set.
'-c' and '-S' both instruct the compiler to stop at different stages of
the pipeline ('-S' after compiling, '-c' after assembling), so having
them present together in the same command makes little sense. In this
case, the test wants to stop before assembling because it is looking at
the textual assembly output of the compiler for either '%fs' or '%gs',
so remove '-c' from the list of arguments to resolve the error.
All versions of GCC continue to work after this change, along with
versions of clang that do or do not contain the change mentioned above.

"This contains two fixes for this merge window:
VFS:
- I noticed that it is possible for a privileged user to mount most
filesystems with a non-initial user namespace in sb->s_user_ns.
When fsopen() is called in a non-init namespace the caller's
namespace is recorded in fs_context->user_ns. If the returned file
descriptor is then passed to a process privileged in init_user_ns,
that process can call fsconfig(fd_fs, FSCONFIG_CMD_CREATE*),
creating a new superblock with sb->s_user_ns set to the namespace
of the process which called fsopen().
This is problematic as only filesystems that raise FS_USERNS_MOUNT
are known to be able to support a non-initial s_user_ns. Others may
suffer security issues, on-disk corruption or outright crash the
kernel. Prevent that by restricting such delegation to filesystems
that allow FS_USERNS_MOUNT.
Note, that this delegation requires a privileged process to
actually create the superblock so either the privileged process is
cooperaing or someone must have tricked a privileged process into
operating on a fscontext file descriptor whose origin it doesn't
know (a stupid idea).
The bug dates back to about 5 years afaict.

In the legacy mount api hostfs allows to specify the host directory

"The highlight is the establishment of a minimum version for the Rust
toolchain, including 'rustc' (and bundled tools) and 'bindgen'.
The initial minimum will be the pinned version we currently have, i.e.
we are just widening the allowed versions. That covers three stable
Rust releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow),
plus beta, plus nightly.
This should already be enough for kernel developers in distributions
that provide recent Rust compiler versions routinely, such as Arch
Linux, Debian Unstable (outside the freeze period), Fedora Linux,
Gentoo Linux (especially the testing channel), Nix (unstable) and
openSUSE Slowroll and Tumbleweed.
In addition, the kernel is now being built-tested by Rust's pre-merge
CI. That is, every change that is attempting to land into the Rust
compiler is tested against the kernel, and it is merged only if it
passes. Similarly, the bindgen tool has agreed to build the kernel in
their CI too.
Thus, with the pre-merge CI in place, both projects hope to avoid
unintentional changes to Rust that break the kernel. This means that,
in general, apart from intentional changes on their side (that we will
need to workaround conditionally on our side), the upcoming Rust
compiler versions should generally work.
In addition, the Rust project has proposed getting the kernel into
stable Rust (at least solving the main blockers) as one of its three
flagship goals for 2024H2 [1].
I would like to thank Niko, Sid, Emilio et al. for their help
promoting the collaboration between Rust and the kernel.
Toolchain and infrastructure:
- Support several Rust toolchain versions.
- Support several bindgen versions.
- Remove 'cargo' requirement and simplify 'rusttest', thanks to
'alloc' having been dropped last cycle.
- Provide proper error reporting for the 'rust-analyzer' target.
'kernel' crate:
- Add 'uaccess' module with a safe userspace pointers abstraction.
- Add 'page' module with a 'struct page' abstraction.
- Support more complex generics in workqueue's 'impl_has_work!'
macro.
'macros' crate:
- Add 'firmware' field support to the 'module!' macro.
- Improve 'module!' macro documentation.

"Most of this is a treewide change to of_property_for_each_u32() which
was small enough to do in one go before rc1 and avoids the need to
create of_property_for_each_u32_some_new_name().
- Treewide conversion of of_property_for_each_u32() to drop internal
arguments making struct property opaque

Pull firewire fixes from Takashi Sakamoto:
"The recent integration of compiler collections introduced the
technology to check flexible array length at runtime by providing
proper annotations. In v6.10 kernel, a patch was merged into firewire
subsystem to utilize it, however the annotation was inadequate.
There is also the related change for the flexible array in sound
subsystem, but it causes a regression where the data in the payload of
isochronous packet is incorrect for some devices. These bugs are now
fixed"
