Since the integer wrapping sanitizer's behavior depends on its associated
.scl file, we must force a full rebuild if the file changes. If not,
instrumentation may differ between targets based on when they were built.
Generate a new header file, integer-wrap.h, any time the Clang .scl
file changes. Include the header file in compiler-version.h when its
associated feature name, INTEGER_WRAP, is defined. This will be picked
up by fixdep and force rebuilds where needed.

While the randstruct GCC plugin was being rebuilt if the randstruct seed

Currently, to statically initialize the struct members of the `type`
object created by _DEFINE_FLEX(), the internal `obj` member must be
explicitly referenced at the call site. See:
struct flex {
int a;
int b;
struct foo flex_array[];
};
_DEFINE_FLEX(struct flex, instance, flex_array,
FIXED_SIZE, = {
.obj = {
.a = 0,
.b = 1,
},
});
This leaks _DEFINE_FLEX() internal implementation details and make
the helper harder to use and read.
Fix this and allow for a more natural and intuitive C99 init-style:
_DEFINE_FLEX(struct flex, instance, flex_array,
FIXED_SIZE, = {
.a = 0,
.b = 1,
});
Note that before these changes, the `initializer` argument was optional,
but now it's required.
Also, update "counter" member initialization in DEFINE_FLEX().

The intent is to re-use the INT3472 code for parsing Intel camera sensor
GPIOs and mapping them to the sensor for the atomisp driver, which
currently has duplicate code.
On atomisp devices there is no special INT3472 ACPI device, instead
the Intel _DSM to get the GPIO type is part of the ACPI device for
the sensor itself.
To deal with this the mapping is done from ipu_bridge_init() instead of
from a platform-device probe() function, there is no device to tie
the lifetime of the gpiod_get() calls done by the INT3472 code to.
Switch from devm_gpiod_get() to plain gpiod_get() + explicit gpiod_put()
calls, to prepare for the code being re-used in the atomisp driver.

These are not shown in enabled_functions. Add a "subops:" section to the

the subops is from the function_graph infrastructure, then show the entry

Adjust how the CSEE direct call hack is used.
The results of months of testing combined with help from ASUS to
determine the actual cause of suspend issues has resulted in this
refactoring which immensely improves the reliability for devices which
do not have the following minimum MCU FW version:
- ROG Ally X: 313
- ROG Ally 1: 319
For MCU FW versions that match the minimum or above the CSEE hack is
disabled and mcu_powersave set to on by default as there are no
negatives beyond a slightly slower device reinitialization due to the
MCU being powered off.
As this is set only at module load time, it is still possible for
mcu_powersave sysfs attributes to change it at runtime if so desired.

SDEI usually initialize with the ACPI table, but on platforms where
ACPI is not used, the SDEI feature can still be used to handle
specific firmware calls or other customized purposes. Therefore, it
is not necessary for ARM_SDE_INTERFACE to depend on ACPI_APEI_GHES.
In commit dc4e8c07e9e2 ("ACPI: APEI: explicit init of HEST and GHES
in acpi_init()"), to make APEI ready earlier, sdei_init was moved
into acpi_ghes_init instead of being a standalone initcall, adding
ACPI_APEI_GHES dependency to ARM_SDE_INTERFACE. This restricts the
flexibility and usability of SDEI.
This patch corrects the dependency in Kconfig and splits sdei_init()
into two separate functions: sdei_init() and acpi_sdei_init().
sdei_init() will be called by arch_initcall and will only initialize
the platform driver, while acpi_sdei_init() will initialize the
device from acpi_ghes_init() when ACPI is ready. This allows the
initialization of SDEI without ACPI_APEI_GHES enabled.

This means that KASAN will correctly poison the correct spans of requested

XFS will be able to support large atomic writes (atomic write > 1x block)
in future. This will be achieved by using different operating methods,
depending on the size of the write.
Specifically a new method of operation based in FS atomic extent remapping
will be supported in addition to the current HW offload-based method.
The FS method will generally be appreciably slower performing than the
HW-offload method. However the FS method will be typically able to
contribute to achieving a larger atomic write unit max limit.
XFS will support a hybrid mode, where HW offload method will be used when
possible, i.e. HW offload is used when the length of the write is
supported, and for other times FS-based atomic writes will be used.
As such, there is an atomic write length at which the user may experience
appreciably slower performance.
Advertise this limit in a new statx field, stx_atomic_write_unit_max_opt.
When zero, it means that there is no such performance boundary.
Masks STATX{_ATTR}_WRITE_ATOMIC can be used to get this new field. This is
ok for older kernels which don't support this new field, as they would
report 0 in this field (from zeroing in cp_statx()) already. Furthermore
those older kernels don't support large atomic writes - apart from block
fops, but there would be consistent performance there for atomic writes
in range [unit min, unit max].

arch_topology.c provides functionality to parse and scale CPU capacity.
It also provides a corresponding sysfs interface. Some architectures
parse and scale CPU capacity differently as per their own needs. On
Intel processors, for instance, it is responsibility of the Intel
P-state driver.
Relocate the implementation of that interface to a common location in
topology.c. Architectures can use the interface and populate it using
their own mechanisms.
An alternative approach would be to compile arch_topology.c even if
not needed only to get this interface. This approach would create
duplicated and conflicting functionality and data structures.

Add a new Kconfig CONFIG_UBSAN_KVM_EL2 for KVM which enables
UBSAN for EL2 code (in protected/nvhe/hvhe) modes.
This will re-use the same checks enabled for the kernel for
the hypervisor. The only difference is that for EL2 it always
emits a "brk" instead of implementing hooks as the hypervisor
can't print reports.
The KVM code will re-use the same code for the kernel
"report_ubsan_failure()" so #ifdefs are changed to also have this
code for CONFIG_UBSAN_KVM_EL2

report_ubsan_failure() doesn't use argument regs, and soon it will
be called from the hypervisor context were regs are not available.
So, remove the unused argument.

Stubs in the header file for !CONFIG_STM32_FIREWALL case should be both
static and inline, because they do not come with earlier declaration and
should be inlined in every unit including the header.

Use the new guards to get and lock the interrupt descriptor and tidy up the

Make the return value boolean to reflect it's meaning.

Accidentally spotted while trying to understand what else needs
to be renamed to netif_ prefix. Most of the calls to dev_set_promiscuity
are adjacent to dev_set_allmulti or dev_disable_lro so it should
be safe to add the lock. Note that new netif_set_promiscuity is
currently unused, the locked paths call __dev_set_promiscuity directly.
