The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Commit b9873755a6c8 ("misc: Add Nitro Secure Module driver") adds Nitro
Security Module support, which selects the non-existing config CBOR.
In the development of the commit, there was initially some code for CBOR
independent of the driver, and the driver included this code with the line
'select CBOR'. This code for CBOR was later reduced to its bare minimum of
functionality and included into the driver itself. The select CBOR remained
unnoticed and was left behind without having any further purpose.
Remove selecting the non-existing config CBOR.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Greg lamented:
"Ick, sorry about that, obviously this test isn't actually built by any

A quick and dirty way to prevent this problem going forward is to always
compile ndtest.ko whenever nfit_test is built. While this still does not
expose the test code to any of the known build bots, it at least makes
it the case that anyone that runs the x86 tests also compiles the
powerpc test.
I.e. the Intel NVDIMM maintainers are less likely to fall into this hole
in the future.

All of the other constants in this file are defined using enums, so make
the constants more consistent by defining the ioctls in an enum as well.
This is necessary for Rust Binder since the _IO macros are too
complicated for bindgen to see that they expand to integer constants.
Replacing the #defines with an enum forces bindgen to evaluate them
properly, which allows us to access them from Rust.
I originally intended to include this change in the first patch of the
Rust Binder patchset [1], but at plumbers Carlos Llamas told me that
this change has been discussed previously [2] and suggested that I send
it upstream separately.

The dependencies in the mei framework are inconsistent, with some symbols
using 'select INTEL_MEI' to force it being enabled and others using
'depends on INTEL_MEI'.
In general, one should not select user-visible symbols, so change all
of these to normal dependencies, but change the default on INTEL_MEI to
be enabled when building a kernel for an Intel CPU with ME or a generic
x86 kernel.
Having consistent dependencies makes the 'menuconfig' listing more
readable by using proper indentation.
A large if/endif block is just a simpler syntax than repeating the
dependencies for each symbol.

On STM32MP25, OTP area may be read/written by using BSEC (boot, security
and OTP control). The BSEC internal peripheral is only managed by the
secure world.
The 12 Kbits of OTP (effective) are organized into the following regions:
- lower OTP (OTP0 to OTP127) = 4096 lower OTP bits,
bitwise (1-bit) programmable
- mid OTP (OTP128 to OTP255) = 4096 middle OTP bits,
bulk (32-bit) programmable
- upper OTP (OTP256 to OTP383) = 4096 upper OTP bits,
bulk (32-bit) programmable,
only accessible when BSEC is in closed state.
As HWKEY and ECIES key are only accessible by ROM code;
only 368 OTP words are managed in this driver (OTP0 to OTP267).
This patch adds the STM32MP25 configuration for reading and writing
the OTP data using the OP-TEE BSEC TA services.

The binary content of nvmem devices is available to the user so in the
easiest cases, finding the content of a cell is rather easy as it is
just a matter of looking at a known and fixed offset. However, nvmem
layouts have been recently introduced to cope with more advanced
situations, where the offset and size of the cells is not known in
advance or is dynamic. When using layouts, more advanced parsers are
used by the kernel in order to give direct access to the content of each
cell, regardless of its position/size in the underlying
device. Unfortunately, these information are not accessible by users,
unless by fully re-implementing the parser logic in userland.
Let's expose the cells and their content through sysfs to avoid these
situations. Of course the relevant NVMEM sysfs Kconfig option must be
enabled for this support to be available.
Not all nvmem devices expose cells. Indeed, the .bin_attrs attribute
group member will be filled at runtime only when relevant and will
remain empty otherwise. In this case, as the cells attribute group will
be empty, it will not lead to any additional folder/file creation.
Exposed cells are read-only. There is, in practice, everything in the
core to support a write path, but as I don't see any need for that, I
prefer to keep the interface simple (and probably safer). The interface
is documented as being in the "testing" state which means we can later
add a write attribute if though relevant.

Current layout support was initially written without modules support in
mind. When the requirement for module support rose, the existing base
was improved to adopt modularization support, but kind of a design flaw
was introduced. With the existing implementation, when a storage device
registers into NVMEM, the core tries to hook a layout (if any) and
populates its cells immediately. This means, if the hardware description
expects a layout to be hooked up, but no driver was provided for that,
the storage medium will fail to probe and try later from
scratch. Even if we consider that the hardware description shall be
correct, we could still probe the storage device (especially if it
contains the rootfs).
One way to overcome this situation is to consider the layouts as
devices, and leverage the native notifier mechanism. When a new NVMEM
device is registered, we can populate its nvmem-layout child, if any,
and wait for the matching to be done in order to get the cells (the
waiting can be easily done with the NVMEM notifiers). If the layout
driver is compiled as a module, it should automatically be loaded. This
way, there is no strong order to enforce, any NVMEM device creation
or NVMEM layout driver insertion will be observed as a new event which
may lead to the creation of additional cells, without disturbing the
probes with costly (and sometimes endless) deferrals.
In order to achieve that goal we create a new bus for the nvmem-layouts
with minimal logic to match nvmem-layout devices with nvmem-layout
drivers. All this infrastructure code is created in the layouts.c file.

Merge tag '6.7-rc4-smb3-client-fixes' of git://git.samba.org/sfrench/cifs-2.6
Pull smb client fixes from Steve French:
"Six smb3 client fixes:
- Fixes for copy_file_range and clone (cache invalidation and file
size), also addresses an xfstest failure
- Fix to return proper error if REMAP_FILE_DEDUP set (also fixes
xfstest generic/304)
- Fix potential null pointer reference with DFS
- Multichannel fix addressing (reverting an earlier patch) some of
the problems with enabling/disabling channels dynamically
Still working on a followon multichannel fix to address another issue
found in reconnect testing that will send next week"

smb: client: fix potential NULL deref in parse_dfs_referrals()
cifs: Fix flushing, invalidation and file size with FICLONE

We can see that "bswap32: Takes an unsigned 32-bit number in either big-
or little-endian format and returns the equivalent number with the same
bit width but opposite endianness" in BPF Instruction Set Specification,
so it should clear the upper 32 bits in "case 32:" for both BPF_ALU and
BPF_ALU64.

We can see that "Short form of movsx, dst_reg = (s8,s16,s32)src_reg" in
include/linux/filter.h, additionally, for BPF_ALU64 the value of the
destination register is unchanged whereas for BPF_ALU the upper 32 bits
of the destination register are zeroed, so it should clear the upper 32
bits for BPF_ALU.

By the way, the bpf selftest case "./test_progs -t verifier_movsx" can
also be fixed with this patch.

Currently, we store syscall nr in pt_regs::regs[11] and syscall execve()
accidentally overrides it during its execution:
sys_execve()
-> do_execve()
-> do_execveat_common()
-> bprm_execve()
-> exec_binprm()
-> search_binary_handler()
-> load_elf_binary()
-> ELF_PLAT_INIT()
ELF_PLAT_INIT() reset regs[11] to 0, so in syscall_exit_to_user_mode()
we later get a wrong syscall nr. This breaks tools like execsnoop since
it relies on execve() tracepoints.
Skip pt_regs::regs[11] reset in ELF_PLAT_INIT() to fix the issue.
