Merge series from Biju Das <biju.das.jz@bp.renesas.com>:
The xSPI IP found on RZ/G3E SoC similar to RPC-IF interface, but it
can support writes on memory-mapped area. Even though the registers are
different, the rpcif driver code can be reused for xSPI by adding wrapper
functions.

Some NETC functionality is controlled using control messages sent to the
hardware using BD ring interface with 32B descriptor similar to transmit
BD ring used on ENETC. This BD ring interface is referred to as command
BD ring. It is used to configure functionality where the underlying
resources may be shared between different entities or being too large to
configure using direct registers. Therefore, a messaging protocol called
NETC Table Management Protocol (NTMP) is provided for exchanging
configuration and management information between the software and the
hardware using the command BD ring interface.
For the management protocol of LS1028A has been retroactively named NTMP
1.0, and its implementation is in enetc_cbdr.c and enetc_qos.c. However,
NTMP of i.MX95 has been upgraded to version 2.0, which is incompatible
with LS1028A, because the message formats have been changed. Therefore,
add the netc-lib driver to support NTMP 2.0 to operate various tables.
Note that, only MAC address filter table and RSS table are supported at
the moment. More tables will be supported in subsequent patches.
It is worth mentioning that the purpose of the netc-lib driver is to
provide some NTMP-based generic interfaces for ENETC and NETC Switch
drivers. Currently, it only supports the configurations of some tables.
Interfaces such as tc flower and debugfs will be added in the future.

Introduce new TSM Measurement helper library (tsm-mr) for TVM guest drivers
to expose MRs (Measurement Registers) as sysfs attributes, with Crypto
Agility support.
Add the following new APIs (see include/linux/tsm-mr.h for details):
- tsm_mr_create_attribute_group(): Take on input a `struct
tsm_measurements` instance, which includes one `struct
tsm_measurement_register` per MR with properties like `TSM_MR_F_READABLE`
and `TSM_MR_F_WRITABLE`, to determine the supported operations and create
the sysfs attributes accordingly. On success, return a `struct
attribute_group` instance that will typically be included by the guest
driver into `miscdevice.groups` before calling misc_register().
- tsm_mr_free_attribute_group(): Free the memory allocated to the attrubute
group returned by tsm_mr_create_attribute_group().
tsm_mr_create_attribute_group() creates one attribute for each MR, with
names following this pattern:
MRNAME[:HASH]
- MRNAME - Placeholder for the MR name, as specified by
`tsm_measurement_register.mr_name`.
- :HASH - Optional suffix indicating the hash algorithm associated with
this MR, as specified by `tsm_measurement_register.mr_hash`.
Support Crypto Agility by allowing multiple definitions of the same MR
(i.e., with the same `mr_name`) with distinct HASH algorithms.
NOTE: Crypto Agility, introduced in TPM 2.0, allows new hash algorithms to
be introduced without breaking compatibility with applications using older
algorithms. CC architectures may face the same challenge in the future,
needing new hashes for security while retaining compatibility with older
hashes, hence the need for Crypto Agility.

The ___ratelimit() function special-cases the jiffies-counter value of zero
as "uninitialized". This works well on 64-bit systems, where the jiffies
counter is not going to return to zero for more than half a billion years
on systems with HZ=1000, but similar 32-bit systems take less than 50 days
to wrap the jiffies counter. And although the consequences of wrapping the
jiffies counter seem to be limited to minor confusion on the duration of
the rate-limiting interval that happens to end at time zero, it is almost
no work to avoid this confusion.
Therefore, introduce a RATELIMIT_INITIALIZED bit to the ratelimit_state
structure's ->flags field so that a ->begin value of zero is no longer
special.

The ratelimit_state structure's ->missed field is sometimes incremented
locklessly, and it would be good to avoid lost counts. This is also
needed to count the number of misses due to trylock failure. Therefore,
convert the ratelimit_state structure's ->missed field to atomic_t.

A number of ratelimit use cases do open-coded access to the
ratelimit_state structure's ->missed field. This works, but is a bit
messy and makes it more annoying to make changes to this field.
Therefore, provide a ratelimit_state_inc_miss() function that increments
the ->missed field, a ratelimit_state_get_miss() function that reads
out the ->missed field, and a ratelimit_state_reset_miss() function
that reads out that field, but that also resets its value to zero.
These functions will replace client-code open-coded uses of ->missed.
In addition, a new ratelimit_state_reset_interval() function encapsulates
what was previously open-coded lock acquisition and direct field updates.

The CPU hotplug handlers are called twice: at prepare and online stage.
Their role is to:
1) Enable/disable a CPU context. This is irrelevant and even buggy at
the prepare stage because the CPU is still offline. On early
secondary CPU up, creating an event attached to that CPU might
silently fail because the CPU context is observed as online but the
context installation's IPI failure is ignored.
2) Update the scope cpumasks and re-migrate the events accordingly in
the CPU down case. This is irrelevant at the prepare stage.
3) Remove the events attached to the context of the offlining CPU. It
even uses an (unnecessary) IPI for it. This is also irrelevant at the
prepare stage.
Also none of the *_PREPARE and *_STARTING architecture perf related CPU
hotplug callbacks rely on CPUHP_PERF_PREPARE.
CPUHP_AP_PERF_ONLINE is enough and the right place to perform the work.

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.

INTEL_INT3472
Move the common.h header file to include/linux/platform_data/x86/int3472.h
and add a "INTEL_INT3472" kernel-symbol-namespace to the exported symbols.
This is a preparation patch for exporting some more symbols for re-use in
the atomisp driver.

This fixes the regression introduced by 50c1241e6a8a ("Bluetooth: l2cap:
Check encryption key size on incoming connection") introduced a check for
l2cap_check_enc_key_size which checks for hcon->enc_key_size which may
not be initialized if HCI_OP_READ_ENC_KEY_SIZE is still pending.
If the key encryption size is known, due previously reading it using
HCI_OP_READ_ENC_KEY_SIZE, then store it as part of link_key/smp_ltk
structures so the next time the encryption is changed their values are
used as conn->enc_key_size thus avoiding the racing against
HCI_OP_READ_ENC_KEY_SIZE.
Now that the enc_size is stored as part of key the information the code
then attempts to check that there is no downgrade of security if
HCI_OP_READ_ENC_KEY_SIZE returns a value smaller than what has been
previously stored.

The function graph infrastructure uses subops of the function tracer.
These are not shown in enabled_functions. Add a "subops:" section to the
enabled_functions line to show what functions are attached via subops. If
the subops is from the function_graph infrastructure, then show the entry
and return callbacks that are attached.
Here's an example of the output:
schedule_on_each_cpu (1) tramp: 0xffffffffc03ef000 (ftrace_graph_func+0x0/0x60) ->ftrace_graph_func+0x0/0x60 subops: {ent:trace_graph_entry+0x0/0x20 ret:trace_graph_return+0x0/0x150}

commit ba47652ba655 ("media: meye: remove this deprecated driver")
removed the meye driver but left behind the code in sony-laptop.c
which that driver used to call.
Remove the sony_pic_camera_command() function, and the set of
defines (SONY_PIC_COMMAND_*) in a header used for the interface
and the static helpers it called.
Cleanup remaining #defines.

SST PP revision 2 added fabric 1 P0, P1 and Pm frequencies. Export them
by using a new IOCTL ISST_IF_GET_PERF_LEVEL_FABRIC_INFO. This IOCTL
requires platforms with SST PP revision 2 or higher.
To accommodate potential future increases in fabric count and avoid ABI
changes, support is extended for up to 8 fabrics.

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.

Change return type of intel_vsec_register() to int. The current
implementation does not indicate if the register fail or not.
Change to return error code if it fails or if INTEL_VSEC config
is not set. This is a preparation step to introduce a new SSRAM
Telemetry driver that will be using this API.

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.

Older drivers and drivers with lower queue counts often have a static
array of queues, rather than allocating structs for each queue on demand.
Add a helper for adding up qstats from a queue range. Expectation is
that driver will pass a queue range [netdev->real_num_*x_queues, MAX).
It was tempting to always use num_*x_queues as the end, but virtio
seems to clamp its queue count after allocating the netdev. And this
way we can trivaly reuse the helper for [0, real_..).

snd_hdac_stream_get_spbmaxfifo() was originally added in 2015
in commit ee8bc4df1b5a ("ALSA: hdac: Add support to enable SPIB for hdac
ext stream")
when it was originally called snd_hdac_ext_stream_set_spbmaxfifo,
it was renamed snd_hdac_ext_stream_get_spbmaxfifo shortly after
and was finally renamed to snd_hdac_stream_get_spbmaxfifo in 2022.
But it was never used.

Introduce struct vm_struct::requested_size so that the requested
(re)allocation size is retained separately from the allocated area size.
This means that KASAN will correctly poison the correct spans of requested
bytes. This also means we can support growing the usable portion of an
allocation that can already be supported by the existing area's existing
allocation.
