There is a regular need in the kernel to provide a way to declare having a
dynamically sized set of trailing elements in a structure. Kernel code should
always use “flexible array members”[1] for these cases. The older style of
one-element or zero-length arrays should no longer be used[2].

Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.
This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.
There are a variety of indentation styles found.
a) 4 spaces + '---help---'
b) 7 spaces + '---help---'
c) 8 spaces + '---help---'
d) 1 space + 1 tab + '---help---'
e) 1 tab + '---help---' (correct indentation)
f) 1 tab + 1 space + '---help---'
g) 1 tab + 2 spaces + '---help---'
In order to convert all of them to 1 tab + 'help', I ran the
following commend:
$ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

Pull remoteproc updates from Bjorn Andersson:
"This introduces device managed versions of functions used to register
remoteproc devices, add support for remoteproc driver specific
resource control, enables remoteproc drivers to specify ELF class and
machine for coredumps. It integrates pm_runtime in the core for
keeping resources active while the remote is booted and holds a wake
source while recoverying a remote processor after a firmware crash.
It refactors the remoteproc device's allocation path to simplify the
logic, fix a few cleanup bugs and to not clone const strings onto the
heap. Debugfs code is simplifies using the DEFINE_SHOW_ATTRIBUTE and a
zero-length array is replaced with flexible-array.
A new remoteproc driver for the JZ47xx VPU is introduced, the Qualcomm
SM8250 gains support for audio, compute and sensor remoteprocs and the
Qualcomm SC7180 modem support is cleaned up and improved.
The Qualcomm glink subsystem-restart driver is merged into the main
glink driver, the Qualcomm sysmon driver is extended to properly
notify remote processors about all other remote processors' state
transitions"

Pull ARM SoC updates from Arnd Bergmann:
"One new platform gets added, the Realtek RTD1195, which is an older
Cortex-a7 based relative of the RTD12xx chips that are already
supported in arch/arm64. The platform may also be extended to support
running 32-bit kernels on those 64-bit chips for memory-constrained
machines.
In the Renesas shmobile platform, we gain support for "RZ/G1H" or
R8A7742, an eight-core chip based on Cortex-A15 and Cortex-A7 cores,
originally released in 2016 as one of the last high-end 32-bit
designs.
There is ongoing cleanup for the integrator, tegra, imx, and omap2
platforms, with integrator getting very close to the goal of having
zero code in arch/arm/, and omap2 moving more of the chip specifics
from old board code into device tree files.
The Versatile Express platform is made more modular, with built-in
drivers now becoming loadable modules. This is part of a greater
effort for the Android OS to have a common kernel binary for all
platforms and any platform specific code in loadable modules.
The PXA platform drops support for Compulab's pxa2xx boards that had
rather unusual flash and PCI drivers but no known users remaining. All
device drivers specific to those boards can now get removed as well.
Across platforms, there is ongoing cleanup, with Geert and Rob

The Texas Instruments K3 Multicore SoC platforms have chipid module which
is represented by CTRLMMR_xxx_JTAGID register and contains information
about SoC id and revision.
Bits:
31-28 VARIANT Device variant
27-12 PARTNO Part number
11-1 MFG Indicates TI as manufacturer (0x17)
1 Always 1
This patch adds corresponding driver to identify the TI K3 SoC family and
revision, and registers this information with the SoC bus. It is available
under /sys/devices/soc0/ for user space, and can be checked, where needed,
in Kernel using soc_device_match().
Identification is done by:
- checking MFG to be TI ID
- retrieving Device variant (revision)
- retrieving Part number and convert it to the family
- retrieving machine from DT "/model"
Example J721E:
# cat /sys/devices/soc0/{machine,family,revision}
Texas Instruments K3 J721E SoC

The Qualcomm SPM cpuidle driver seems to be the last driver still
using the generic ARM CPUidle infrastructure.
Converting it actually allows us to simplify the driver,
and we end up being able to remove more lines than adding new ones:
- We can parse the CPUidle states in the device tree directly
with dt_idle_states (and don't need to duplicate that
functionality into the spm driver).
- Each "saw" device managed by the SPM driver now directly
registers its own cpuidle driver, removing the need for
any global (per cpu) state.
The device tree binding is the same, so the driver stays
compatible with all old device trees.

Qualcomm driver updates for v5.8
This contains a large set of cleanups, bug fixes, general improvements
and documentation fixes for the RPMH driver. It adds a debugfs mechanism
for inspecting Command DB. Socinfo got the "soc_id" attribute defines
and definitions for a various variants of MSM8939.
RPMH, RPMPD and RPMHPD where made possible to build as modules, but RPMH
had to be reverted due to a compilation issue when tracing is enabled.
RPMHPD gained power-domains for the SM8250 voltage corners.
The SCM driver gained fixes for two build warnings and the SMP2P had an
unnecessary error print removed.

The current codebase makes use of one-element arrays in the following
form:
struct something {
int length;
u8 data[1];
};
struct something *instance;
instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL);
instance->length = size;
memcpy(instance->data, source, size);
but the preferred mechanism to declare variable-length types such as
these ones is a flexible array member[1][2], introduced in C99:
struct foo {
int stuff;
struct boo array[];
};
By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on. So, replace
the one-element array with a flexible-array member.
Also, make use of the new struct_size() helper to properly calculate the
size of struct qe_firmware.
This issue was found with the help of Coccinelle and, audited and fixed
_manually_.

In order to determine the number of L2 cache ways enabled at runtime,
implement a private attribute ("number_of_ways_enabled"). Reading this
attribute returns the number of enabled L2 cache ways at runtime.
Using riscv_set_cacheinfo_ops() hook a custom function, that returns
this private attribute, to the generic ops structure which is used by
cache_get_priv_group() in cacheinfo framework.
