Use the dev_err_probe() helper to log the errors on every error path in
the probe function and its sub-functions. This includes
* adding error messages where there was none
* converting over dev_err/dev_warn
* removing the top-level error message after mtk_cpu_dvfs_info_init() is
called, since every error path inside that function already logs the
error reason. This gets rid of the misleading error message when probe
is deferred:

Some of LoongArch processors (Loongson-3 series) support DVFS, their
IOCSR.FEATURES has IOCSRF_FREQSCALE set. And they has a micro-core in
the package called SMC (System Management Controller), which can be
used to detect temperature, control fans, scale frequency and voltage,
etc.
The Loongson-3 CPUFreq driver is very simple now, it communicate with
SMC, get DVFS info, set target frequency from CPUFreq core, and so on.
There is a command list to interact with SMC, widely-used commands in
the CPUFreq driver include:
CMD_GET_VERSION: Get SMC firmware version.
CMD_GET_FEATURE: Get enabled SMC features.
CMD_SET_FEATURE: Enable SMC features, such as basic DVFS, BOOST.
CMD_GET_FREQ_LEVEL_NUM: Get the number of all frequency levels.
CMD_GET_FREQ_BOOST_LEVEL: Get the first boost frequency level.
CMD_GET_FREQ_LEVEL_INFO: Get the detail info of a frequency level.
CMD_GET_FREQ_INFO: Get the current frequency.
CMD_SET_FREQ_INFO: Set the target frequency.
In future we will add automatic frequency scaling, which is similar to
Intel's HWP (HardWare P-State).

On shared memory CPPC systems, with amd_pstate=active mode, the change
in scaling_max_freq doesn't get written to the shared memory
region. Due to this, the writes to the scaling_max_freq sysfs file
don't take effect. Fix this by propagating the scaling_max_freq
changes to the shared memory region.

- Avoid possible crash when PCI hotplug races with error handling
- Fix kexec crash caused by scv being disabled before other CPUs

Thanks to Anjali K, Ganesh Goudar, Gautam Menghani, Jinglin Wen,

selftests/powerpc: Fix build with USERCFLAGS set
powerpc/pseries: Fix scv instruction crash with kexec
powerpc/eeh: avoid possible crash when edev->pdev changes
powerpc/pseries: Whitelist dtl slub object for copying to userspace
powerpc/64s: Fix unnecessary copy to 0 when kernel is booted at address 0
Currently building the powerpc selftests with USERCFLAGS set to anything
causes the build to break:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
...
gcc -Wno-error cache_shape.c ...
cache_shape.c:18:10: fatal error: utils.h: No such file or directory
18 | #include "utils.h"
| ^~~~~~~~~
compilation terminated.
This happens because the USERCFLAGS are added to CFLAGS in lib.mk, which
causes the check of CFLAGS in powerpc/flags.mk to skip setting CFLAGS at
all, resulting in none of the usual CFLAGS being passed. That can
be seen in the output above, the only flag passed to the compiler is
-Wno-error.
Fix it by dropping the conditional setting of CFLAGS in flags.mk.
Instead always set CFLAGS, but also append USERCFLAGS if they are set.
Note that appending to CFLAGS (with +=) wouldn't work, because flags.mk
is included by multiple Makefiles (to support partial builds), causing
CFLAGS to be appended to multiple times. Additionally that would place
the USERCFLAGS prior to the standard CFLAGS, meaning the USERCFLAGS
couldn't override the standard flags. Being able to override the
standard flags is desirable, for example for adding -Wno-error.
With the fix in place, the CFLAGS are set correctly, including the
USERCFLAGS:
$ make -C tools/testing/selftests/powerpc V=1 USERCFLAGS=-Wno-error
...
gcc -std=gnu99 -O2 -Wall -Werror -DGIT_VERSION='"v6.10-rc2-7-gdea17e7e56c3"'

ima: fix wrong zero-assignment during securityfs dentry remove
The Makefile open-codes compiler invocations that ../lib.mk already
provides.
Avoid this by using a Make feature that allows setting per-target
variables, which in this case are: CFLAGS and LDFLAGS. This approach
generates the exact same compiler invocations as before, but removes all
of the code duplication, along with the quirky mangled variable names.
So now the Makefile is smaller, less unusual, and easier to read.
The new dependencies are listed after including lib.mk, in order to
let lib.mk provide the first target ("all:"), and are grouped together
with their respective source file dependencies, for visual clarity.

There were a couple of errors here:
1. TEST_GEN_PROGS was incorrectly prepending $(OUTPUT) to each program
to be built. However, lib.mk already does that because it assumes "bare"
program names are passed in, so this ended up creating
$(OUTPUT)/$(OUTPUT)/file.c, which of course won't work as intended.
2. lib.mk was included before TEST_GEN_PROGS was set, which led to
lib.mk's "all:" target not seeing anything to rebuild.
So nothing worked, which caused the author to force things by creating
an "all:" target locally--while still including ../lib.mk.
Fix all of this by including ../lib.mk at the right place, and removing
the $(OUTPUT) prefix to the programs to be built, and removing the
duplicate "all:" target.

When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...there are several warnings, and an error. This fixes all of those and
allows these tests to run and pass.
1. Fix linker error (undefined reference to memcpy) by providing a local
version of memcpy.
2. clang complains about using this form:
if (g = h & 0xf0000000)
...so factor out the assignment into a separate step.
3. The code is passing a signed const char* to elf_hash(), which expects
a const unsigned char *. There are several callers, so fix this at
the source by allowing the function to accept a signed argument, and
then converting to unsigned operations, once inside the function.
4. clang doesn't have __attribute__((externally_visible)) and generates
a warning to that effect. Fortunately, gcc 12 and gcc 13 do not seem
to require that attribute in order to build, run and pass tests here,
so remove it.

may_open() does not allow a directory to be opened with the write access.
However, some writing flags set by client result in adding write access
on server, making ksmbd incompatible with FUSE file system. Simply, let's
discard the write access when opening a directory.

Merge tag 'i2c-host-fixes-6.10-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
This tag includes a nice fix in the PNX driver that has been
pending for a long time. Piotr has replaced a potential lock in
the interrupt context with a more efficient and straightforward
handling of the timeout signaling.
DTS for Nokia N900 incorrectly specifies "active high" polarity for
the reset line, while the chip documentation actually specifies it as
"active low". In the past the driver fudged gpiod API and inverted
the logic internally, but it was changed in d0d89493bf.
Fixes: d0d89493bf ("Input: tsc2004/5 - switch to using generic device properties")
