/proc/self/mountinfo prints out the sb->s_subtype after the type. This
is particularly useful for disambiguating FUSE mounts (at least when the
userland driver bothers to set it). Add STATMOUNT_FS_SUBTYPE and claim
one of the __spare2 fields to point to the offset into the str[] array.

When one of the statmount_string() handlers doesn't emit anything to
seq, the kernel currently sets the corresponding flag and emits an empty
string.
Given that statmount() returns a mask of accessible fields, just leave
the bit unset in this case, and skip any NULL termination. If nothing
was emitted to the seq, then the EOVERFLOW and EAGAIN cases aren't
applicable and the function can just return immediately.

The comment suggests a hash or array approach to
store the active requests. Currently it iterates
through all the active requests and when found
deletes the requested request, in the linked list.
However io_cancel() isn’t a frequently used operation,
and optimizing it wouldn’t bring a substantial benefit
to real users and the increased complexity of maintaining
a hashtable for this would be significant and will slow
down other operation. Therefore remove this TODO
to avoid people spending time improving this.

Devices block sizes may change. One of these cases is a loop device by
using ioctl LOOP_SET_BLOCK_SIZE.
While this may cause other issues like IO being rejected, in the case of
hfsplus, it will allocate a block by using that size and potentially write
out-of-bounds when hfsplus_read_wrapper calls hfsplus_submit_bio and the
latter function reads a different io_size.
Using a new min_io_size initally set to sb_min_blocksize works for the
purposes of the original fix, since it will be set to the max between
HFSPLUS_SECTOR_SIZE and the first seen logical block size. We still use the
max between HFSPLUS_SECTOR_SIZE and min_io_size in case the latter is not
initialized.
Tested by mounting an hfsplus filesystem with loop block sizes 512, 1024
and 4096.
The produced KASAN report before the fix looks like this:

Add coverage for FPMR to fp-ptrace. FPMR can be available independently of
SVE and SME, if SME is supported then FPMR is cleared by entering and
exiting streaming mode. As with other registers we generate random values
to load into the register, we restrict these to bitfields which are always
defined. We also leave bitfields where the valid values are affected by
the set of supported FP8 formats zero to reduce complexity, it is unlikely
that specific bitfields will be affected by ptrace issues.

Currently we don't build the PAC selftests when building with LLVM=1 since
we attempt to test for PAC support in the toolchain before we've set up the
build system to point at LLVM in lib.mk, which has to be one of the last
things in the Makefile.
Since all versions of LLVM supported for use with the kernel have PAC
support we can just sidestep the issue by just assuming PAC is there when
doing a LLVM=1 build.

After commit 0edb555a65d1 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/regulator to use .remove(),
with the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
A few whitespace changes are done en passant to make indention
consistent.

Simple Card Utils has simple_util_dai which is paired to snd_soc_dai,
and assmus that CPU/Codec DAI and its paired simple_util_dai are same
order for CPU/Codec
simple_util_dai[0] <--> snd_soc_dai[0]
simple_util_dai[1] <--> snd_soc_dai[1]
...
So, it is using same index in for_each loop.
(X) gets simple_util_dai
(Y) gets snd_soc_dai
(Y) for_each_rtd_cpu_dais(.., i, ..) {
(X)(A) udai = simple_props_to_dai_cpu(.., i);
}
(X) for_each_prop_dai_cpu(.., i, ...) {
(Y) dai = snd_soc_rtd_to_cpu(.., i);
...
}
But current Simple Card Utils didn't have simple_util_dai for
dummy DAI. So above (A) will get NULL pointer in such case.
This patch cares simple_util_dai for dummy DAI.

The filechk macro always executes the syscalltbl script (and discards
the output if there are no changes).
Using if_changed is more efficient because it avoids running the script
when the target is up-to-date and the command remains unchanged.

Building the kernel with ARCH=s390 creates a weird arch/arch/ directory.

The root cause is 'targets' in arch/s390/kernel/syscalls/Makefile,
where the relative path is incorrect.
Strictly speaking, 'targets' was not necessary in the first place
because this Makefile uses 'filechk' instead of 'if_changed'.
However, this commit keeps it, as it will be useful when converting
'filechk' to 'if_changed' later.

Rewrite __cmpxchg() in order to get rid of the large inline
assemblies. Convert the one and two byte inline assemblies to
C functions.
The generated code of the new implementation is nearly as good or bad as
the old variant, but easier to read.
Note that the new variants are quite close to the generic cmpxchg_emu_u8()
implementation, however a conversion to the generic variant will not follow
since with mm/vmstat.c there is heavy user of one byte cmpxchg(). A not
inlined variant would have a negative performance impact.
Also note that the calls within __arch_cmpxchg() come with rather pointless
"& 0xff..." operations. They exist only to avoid false positive sparse
warnings like "warning: cast truncates bits from constant value ...".

It's inefficient and confusing to pass the MBSSID config
by value, requiring the whole struct to be copied. Pass
it by reference instead.

Support EHT 1024 aggregation size in TX
The 1024 agg size for RX is supported but not for TX.
This patch adds this support and refactors common parsing logics for
addbaext in both process_addba_resp and process_addba_req into a
function.

Add device tree schema for the Realtek RTL9300 switches. The RTL9300
family is made up of the RTL9301, RTL9302B, RTL9302C and RTL9303. These
have the same SoC differ in the Ethernet switch/SERDES arrangement.
Currently the only supported features are the syscon-reboot and i2c
controllers. The syscon-reboot is needed to be able to reboot the board.
The I2C controllers are slightly unusual because they each own an SCL
pin (GPIO8 for the first controller, GPIO 17 for the second) but have 8
common SDA pins which can be assigned to either controller (but not
both).

On some x86 Bay Trail tablets which shipped with Android as factory OS,
the DSDT is so broken that the PMIC needs to be manually instantiated by
the special x86-android-tablets.ko "fixup" driver for cases like this.
Add an i2c_device_id table so that the driver can match on manually
instantiated i2c_client-s (which lack an ACPI fwnode to match on).

Currently the intel_soc_pmic_bxtwc, intel_soc_pmic_chtwc and
intel_soc_pmic_crc PMIC drivers use more or less free form strings
for their driver name.
Where as intel_soc_pmic_chtdc_ti and intel_soc_pmic_mrfld use the driver's
filename as driver name.
Update the 3 others to also use the driver's filename to make the naming
consistent.

We run into an exhaustion problem with the kernel-allocated filter IDs.
Our allocation problem can be fixed on the user space side,
but the error message in this case was quite misleading:
"Filter with specified priority/protocol not found" (EINVAL)
Specifically when we can't allocate a _new_ ID because filter with
lowest ID already _exists_, saying "filter not found", is confusing.
Kernel allocates IDs in range of 0xc0000 -> 0x8000, giving out ID one
lower than lowest existing in that range. The error message makes sense
when tcf_chain_tp_find() gets called for GET and DEL but for NEW we
need to provide more specific error messages for all three cases:
- user wants the ID to be auto-allocated but filter with ID 0x8000
already exists
- filter already exists and can be replaced, but user asked
for a protocol change
- filter doesn't exist
Caller of tcf_chain_tp_insert_unique() doesn't set extack today,
so don't bother plumbing it in.
