Now that the VSP1 driver supports color spaces, expose them through the
API used by the DU driver. This allows configuring the YCbCr encoding
and quantization used by each plane, ensuring correct color rendering.

To configure a device to a specific performance level, consumer drivers
currently need to determine the OPP based on the exact level and then
set it, resulting in code duplication across drivers.
The new helper API, dev_pm_opp_set_level(), addresses this issue by
providing a streamlined method for consumer drivers to find and set the
OPP based on the desired performance level, thereby eliminating
redundancy.

After 52358dd63e34 ("net: phy: remove function stubs") there's a
problem if CONFIG_MDIO_BUS is set, but CONFIG_PHYLIB is not.
mdiobus_scan() uses phylib functions like get_phy_device().
Bringing back the stub wouldn't make much sense, because it would
allow to compile mdiobus_scan(), but the function would be unusable.
The stub returned NULL, and we have the following in mdiobus_scan():
phydev = get_phy_device(bus, addr, c45);
if (IS_ERR(phydev))
return phydev;
So calling mdiobus_scan() w/o CONFIG_PHYLIB would cause a crash later in
mdiobus_scan(). In general the PHYLIB functionality isn't optional here.
Consequently, MDIO bus providers depend on PHYLIB.
Therefore factor it out and build it together with the libphy core
modules. In addition make all MDIO bus providers under /drivers/net/mdio
depend on PHYLIB. Same applies to enetc MDIO bus provider. Note that
PHYLIB selects MDIO_DEVRES, therefore we can omit this here.

17 years ago, Venki suggested [1] "A future improvement would be to
avoid the range_is_allowed duplication".
The only thing preventing a common implementation is that
phys_mem_access_prot_allowed() expects the range check to exit
immediately when PAT is disabled [2]. I.e. there is no cache conflict to
manage in that case. This cleanup was noticed on the path to
considering changing range_is_allowed() policy to blanket deny /dev/mem
for private (confidential computing) memory.
Note, however that phys_mem_access_prot_allowed() has long since stopped
being relevant for managing cache-type validation due to [3], and [4].

Both CS35L56 and CS42L43 have maximum volumes above 0dB.
However, for many use cases, this can cause distorted audio, depending
various factors, such as other signal-processing elements in the chain,
for example if the audio passes through a gain control before reaching
the amp or the signal path has been tuned for a particular maximum
gain in the amp.
In the cases where systems use the soc_sdw_* drivers, audio above the
0dB volume will likely always be distorted, therefore apply a 0dB
limit to those devices.

The volume control for cs35l56 speakers has a maximum gain of +12 dB.
However, for many use cases, this can cause distorted audio, depending
various factors, such as other signal-processing elements in the chain,
for example if the audio passes through a gain control before reaching
the amp or the signal path has been tuned for a particular maximum
gain in the amp.
In the case of systems which use the soc_sdw_* driver, audio will
likely be distorted in all cases above 0 dB, therefore add a volume
limit of 400, which is 0 dB maximum volume inside this driver.
The volume limit should be applied to both soundwire and soundwire
bridge configurations.

Commit a3e8fe814ad1 ("x86/build: Raise the minimum GCC version to 8.1")
raised the minimum compiler version as enforced by Kbuild to gcc-8.1
and clang-15 for x86.
This is actually the same gcc version that has been discussed as the
minimum for all architectures several times in the past, with little
objection. A previous concern was the kernel for SLE15-SP7 needing to
be built with gcc-7. As this ended up still using linux-6.4 and there
is no plan for an SP8, this is no longer a problem.
Change it for all architectures and adjust the documentation accordingly.
A few version checks can be removed in the process. The binutils
version 2.30 is the lowest version used in combination with gcc-8 on
common distros, so use that as the corresponding minimum.

Merge series from David Lechner <dlechner@baylibre.com>:
In order to achieve a 4 MSPS rate on a 16-bit ADC with a 80 MHz SCLK
using the SPI offload feature of the AXI SPI Engine, we need to shave
off some time that is spent executing unnecessary instructions. There
are a few one-time setup instructions that can be moved so that they
execute only once when the SPI offload trigger is enabled rather than
repeating each time the offload is triggered. Additionally, a recent
change to the IP block allows dropping the SYNC instruction completely.
With these changes, we are left with only the 3 instructions that are
needed to to assert CS, transfer the data, and deassert CS. This makes
3 + 16 * 12.5 ns = 237.5 ns < 250 ns which is comfortably within the
available time period.

Add a helper for replacing the contents of bitfield in memory
with the specified value.
Even though a helper xxx_replace_bits() is available, it is not
well documented, and only reports errors at the run time, which
will not be helpful to catch possible overflow errors due to
incorrect parameter types used.
FIELD_MODIFY(REG_FIELD_C, ®, c) is the wrapper to the code below.
reg &= ~REG_FIELD_C;
reg |= FIELD_PREP(REG_FIELD_C, c);

__BUILD_BUG_ON_ZERO_MSG(), as introduced in [1], makes it possible to
do a static assertions in expressions. The direct benefit is to
provide a meaningful error message instead of the cryptic negative
bitfield size error message currently returned by BUILD_BUG_ON_ZERO():
./include/linux/build_bug.h:16:51: error: negative width in bit-field '<anonymous>'
16 | #define BUILD_BUG_ON_ZERO(e) ((int)(sizeof(struct { int:(-!!(e)); })))
| ^
Get rid of BUILD_BUG_ON_ZERO()'s bitfield size hack. Instead rely on
__BUILD_BUG_ON_ZERO_MSG() which in turn relies on C11's
_Static_assert().
Use some macro magic, similarly to static_assert(), to either use an
optional error message provided by the user or, when omitted, to
produce a default error message by stringifying the tested
expression. With this, for example:
BUILD_BUG_ON_ZERO(1 > 0)
would now throw:
./include/linux/compiler.h:197:62: error: static assertion failed: "1 > 0 is true"
197 | define __BUILD_BUG_ON_ZERO_MSG(e, msg) ((int)sizeof(struct {_Static_assert(!(e), msg);}))
| ^~~~~~~~~~~~~~
Finally, __BUILD_BUG_ON_ZERO_MSG() is already guarded by an:
#ifdef __CHECKER__
So no need any more for that guard clause for BUILD_BUG_ON_ZERO().
Remove it.

Add GENMASK_TYPE() which generalizes __GENMASK() to support different
types, and implement fixed-types versions of GENMASK() based on it.
The fixed-type version allows more strict checks to the min/max values
accepted, which is useful for defining registers like implemented by
i915 and xe drivers with their REG_GENMASK*() macros.
The strict checks rely on shift-count-overflow compiler check to fail
the build if a number outside of the range allowed is passed.
Example:
#define FOO_MASK GENMASK_U32(33, 4)
will generate a warning like:
include/linux/bits.h:51:27: error: right shift count >= width of type [-Werror=shift-count-overflow]
51 | type_max(t) >> (BITS_PER_TYPE(t) - 1 - (h)))))
| ^~
The result is casted to the corresponding fixed width type. For
example, GENMASK_U8() returns an u8. Note that because of the C
promotion rules, GENMASK_U8() and GENMASK_U16() will immediately be
promoted to int if used in an expression. Regardless, the main goal is
not to get the correct type, but rather to enforce more checks at
compile time.
While GENMASK_TYPE() is crafted to cover all variants, including the
already existing GENMASK(), GENMASK_ULL() and GENMASK_U128(), for the
moment, only use it for the newly introduced GENMASK_U*(). The
consolidation will be done in a separate change.

This is a preparation for the upcoming GENMASK_U*() and BIT_U*()
changes. After introducing those new macros, there will be a lot of
scrolling between the #if, #else and #endif.
Add a comment to the #else and #endif preprocessor macros to help keep
track of which context we are in. Also, add new lines to better
visually separate the non-asm and asm sections.

Commit decde1fa209323c7 ("cpumask: Add assign cpu") was merged bypassing
cpumasks reviewers. It adds atomic and non-atomic cpumask_assign_cpu()
helpers.
In the same merge window, commit 5c563ee90a22d3 ("cpumask: introduce
assign_cpu() macro") added the same functionality. So now we have it
duplicated.
__cpumask_assign_cpu() has never been used since introducing, and because
this series reworks the only user of cpumask_assign_cpu(), both functions
become a dead code.

The IMA log is currently copied to the new kernel during kexec 'load'
using ima_dump_measurement_list(). However, the log copied at kexec
'load' may result in loss of IMA measurements that only occurred after
kexec "load'. Setup the needed infrastructure to move the IMA log copy
from kexec 'load' to 'execute'.
Define a new IMA hook ima_update_kexec_buffer() as a stub function.
It will be used to call ima_dump_measurement_list() during kexec 'execute'.
Implement ima_kexec_post_load() function to be invoked after the new
Kernel image has been loaded for kexec. ima_kexec_post_load() maps the
IMA buffer to a segment in the newly loaded Kernel. It also registers
the reboot notifier_block to trigger ima_update_kexec_buffer() at
kexec 'execute'.
Set the priority of register_reboot_notifier to INT_MIN to ensure that the
IMA log copy operation will happen at the end of the operation chain, so
that all the IMA measurement records extended into the TPM are copied

Currently, the function kexec_calculate_store_digests() calculates and
stores the digest of the segment during the kexec_file_load syscall,
where the IMA segment is also allocated.
Later, the IMA segment will be updated with the measurement log at the
kexec execute stage when a kexec reboot is initiated. Therefore, the
digests should be updated for the IMA segment in the normal case. The
problem is that the content of memory segments carried over to the new
kernel during the kexec systemcall can be changed at kexec 'execute'
stage, but the size and the location of the memory segments cannot be
changed at kexec 'execute' stage.
To address this, skip the calculation and storage of the digest for the
IMA segment in kexec_calculate_store_digests() so that it is not added
to the purgatory_sha_regions.
With this change, the IMA segment is not included in the digest
calculation, storage, and verification.

Implement kimage_map_segment() to enable IMA to map the measurement log
list to the kimage structure during the kexec 'load' stage. This function
gathers the source pages within the specified address range, and maps them
to a contiguous virtual address range.
This is a preparation for later usage.
Implement kimage_unmap_segment() for unmapping segments using vunmap().
