A few more Qualcomm driver updates for v6.10
This fixes a sleep-while-atomic issue in pmic_glink, stemming from the
fact that the GLINK callback comes from interrupt context.
It fixes the Bluetooth address in the example of qcom,wcnss, and it
enables UEFI variables on SC8180X devices (Primus and Flex 5G).

The current behavior is to accept any strings as inputs, this results in
an inconsistent result where an unexisting scheduler can be set:
# sysctl -w net.mptcp.scheduler=notdefault
net.mptcp.scheduler = notdefault
This patch changes this behavior by checking for existing scheduler
before accepting the input.

Commit 7e8cdc97148c ("nfc: Add KCOV annotations") added
kcov_remote_start_common()/kcov_remote_stop() pair into nci_rx_work(),
with an assumption that kcov_remote_stop() is called upon continue of
the for loop. But commit d24b03535e5e ("nfc: nci: Fix uninit-value in
nci_dev_up and nci_ntf_packet") forgot to call kcov_remote_stop() before
break of the for loop.

Currently, a Vec<T>'s ptr value, after calling Vec<T>::new(), is
initialized to Unique::dangling(). Hence, in VecExt<T>::reserve(), we're
passing a dangling pointer (instead of NULL) to krealloc() whenever a new
Vec<T>'s backing storage is allocated through VecExt<T> extension
functions.
This only works as long as align_of::<T>(), used by Unique::dangling() to
derive the dangling pointer, resolves to a value between 0x0 and
ZERO_SIZE_PTR (0x10) and krealloc() hence treats it the same as a NULL
pointer however.
This isn't a case we should rely on, since there may be types whose
alignment may exceed the range still covered by krealloc(), plus other
kernel allocators are not as tolerant either.
Instead, pass a real NULL pointer to krealloc_aligned() if Vec<T>'s
capacity is zero.

Utilize set_bit() and test_bit() on worker->flags within io_uring/io-wq
to address potential data races.
The structure io_worker->flags may be accessed through various data
paths, leading to concurrency issues. When KCSAN is enabled, it reveals
data races occurring in io_worker_handle_work and
io_wq_activate_free_worker functions.
BUG: KCSAN: data-race in io_worker_handle_work / io_wq_activate_free_worker

<snip>
Line numbers against commit 18daea77cca6 ("Merge tag 'for-linus' of
git://git.kernel.org/pub/scm/virt/kvm/kvm").
These races involve writes and reads to the same memory location by
different tasks running on different CPUs. To mitigate this, refactor
the code to use atomic operations such as set_bit(), test_bit(), and
clear_bit() instead of basic "and" and "or" operations. This ensures
thread-safe manipulation of worker flags.
Also, move `create_index` to avoid holes in the structure.

Based on the discussion at [1], it would be helpful to mark certain
variables as explicitly "data racy", which would result in KCSAN not
reporting data races involving any accesses on such variables. To do
that, introduce the __data_racy type qualifier:
struct foo {
...
int __data_racy bar;
...
};
In KCSAN-kernels, __data_racy turns into volatile, which KCSAN already
treats specially by considering them "marked". In non-KCSAN kernels the
type qualifier turns into no-op.
The generated code between KCSAN-instrumented kernels and non-KCSAN
kernels is already huge (inserted calls into runtime for every memory
access), so the extra generated code (if any) due to volatile for few
such __data_racy variables are unlikely to have measurable impact on
performance.

Commit 1f2bcb8c8ccd ("gpio: protect the descriptor label with SRCU")
caused a massive drop in performance of requesting GPIO lines due to the
call to synchronize_srcu() on each label change. Rework the code to not
wait until all read-only users are done with reading the label but
instead atomically replace the label pointer and schedule its release
after all read-only critical sections are done.
To that end wrap the descriptor label in a struct that also contains the
rcu_head struct required for deferring tasks using call_srcu() and stop
using kstrdup_const() as we're required to allocate memory anyway. Just
allocate enough for the label string and rcu_head in one go.

bch2_write_super() was looping over online devices multiple times -
dropping and retaking io_ref each time.
This meant it could race with device removal; it could increment the
sequence number on a device but fail to write it - and then if the
device was re-added, it would get confused the next time around thinking
a superblock write was silently dropped.
Fix this by taking io_ref once, and stashing pointers to online devices
in a darray.

Sandisk SN530 NVMe drives have broken MSIs. On systems without MSI-X
support, all commands time out resulting in the following message:
nvme nvme0: I/O tag 12 (100c) QID 0 timeout, completion polled
These timeouts cause the boot to take an excessively-long time (over 20
minutes) while the initial command queue is flushed.
Address this by adding a quirk for drives with buggy MSIs. The lspci

Starting BDB version 239, hdr_dpcd_refresh_timeout is introduced to
backlight BDB data. Commit 700034566d68 ("drm/i915/bios: Define more BDB
contents") updated the backlight BDB data accordingly. This broke the
parsing of backlight BDB data in VBT for versions 236 - 238 (both
inclusive) and hence the backlight controls are not responding on units
with the concerned BDB version.
backlight_control information has been present in backlight BDB data
from at least BDB version 191 onwards, if not before. Hence this patch
extracts the backlight_control information for BDB version 191 or newer.
Tested on Chromebooks using Jasperlake SoC (reports bdb->version = 236).
Tested on Chromebooks using Raptorlake SoC (reports bdb->version = 251).
v2: removed checking the block size of the backlight BDB data

This reverts commit 3f9f231236ce7e48780d8a4f1f8cb9fae2df1e4e.
Using 64bit for 'sync_io' is unnecessary from the gendisk side. This
overflow will not cause any functional impact, except for a UBSAN
warning. Solving this overflow requires introducing additional
calculations and checks which are not necessary. So just keep using
32bit for 'sync_io'.

Discards can access a significant capacity and take longer than the user
expected. A user may change their mind about wanting to run that command
and attempt to kill the process and do something else with their device.
But since the task is uninterruptable, they have to wait for it to
finish, which could be many hours.
Open code blkdev_issue_discard in the BLKDISCARD ioctl handler and check
for a fatal signal at each iteration so the user doesn't have to wait
for their regretted operation to complete naturally.

Most bio operations get basic sanity checking in submit_bio and anything
more complicated than that is done in the callers. Discards are a bit
different from that in that a lot of checking is done in
__blkdev_issue_discard, and the specific errnos for that are returned
to userspace. Move the checks that require specific errnos to the ioctl
handler instead, and just leave the basic sanity checking in submit_bio
for the other handlers. This introduces two changes in behavior:
1) the logical block size alignment check of the start and len is lost
for non-ioctl callers.
This matches what is done for other operations including reads and
writes. We should probably verify this for all bios, but for now
make discards match the normal flow.
2) for non-ioctl callers all errors are reported on I/O completion now
instead of synchronously. Callers in general mostly ignore or log
errors so this will actually simplify the code once cleaned up

Historically, the signed integer overflow sanitizer did not work in the
kernel due to its interaction with `-fwrapv` but this has since been
changed [1] in the newest version of Clang; It was re-enabled in the
kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow
sanitizer").
Let's rework this overflow checking logic to not actually perform an
overflow during the check itself, thus avoiding the UBSAN splat.

RISC-V SoC Kconfig Updates for v6.10
A few different bits of SoC-related Kconfig work. The first part of
this is shared with the DT updates - the modification of all SOC_CANAAN
users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away
from the k230 that is able to be used in a "common" kernel.
The other thing here is the removal of most of the SOC_VENDOR options,
with their ARCH_VENDOR equivalents that've been waiting in the wings for
1 year+ now made visible. Due a lapse on my part when originally adding
the ARCH_VENDOR stuff, the Microchip transition isn't complete - the
_POLARFIRE was a mistake to keep as there's gonna be non-PolarFire

For devices with virt_boundary limit, the driver may provide zero max

The four litmus tests in Documentation/litmus-tests/atomic do not
declare all of their local variables. Although this is just fine for LKMM
analysis by herd7, it causes build failures when run in-kernel by klitmus.
This commit therefore adjusts these tests to declare all local variables.

The ORDERING section of Documentation/atomic_t.txt can easily be read as
saying that conditional atomic RMW operations that fail are ordered when
those operations have the _acquire() or _release() suffixes. This is
not the case, therefore update this section to make it clear that failed
conditional atomic RMW operations provide no ordering.

This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.
Stephen Rostedt reports:
"I went to run my tests on my VMs and the tests hung on boot up.
Unfortunately, the most I ever got out was:
[ 93.607888] Testing event system initcall: OK
[ 93.667730] Running tests on all trace events:
[ 93.669757] Testing all events: OK
[ 95.631064] ------------[ cut here ]------------
Timed out after 60 seconds"
and further debugging points to a possible circular locking dependency
between the console_owner locking and the worker pool locking.
Reverting the commit allows Steve's VM to boot to completion again.
[ This may obviously result in the "[TTM] Buffer eviction failed"
messages again, which was the reason for that original revert. But at
this point this seems preferable to a non-booting system... ]

Intel hardware is capable of programming the Maud/Naud SDPs on its
own based on real-time clocks. While doing so, it takes care
of any deviations from the theoretical values. Programming the registers
explicitly with static values can interfere with this logic. Therefore,
let the HW decide the Maud and Naud SDPs on it's own.

We missed setting the CCS mode during resume and engine resets.
Create a workaround to be added in the engine's workaround list.
This workaround sets the XEHP_CCS_MODE value at every reset.
The issue can be reproduced by running:
$ clpeak --kernel-latency
Without resetting the CCS mode, we encounter a fence timeout:
Fence expiration time out i915-0000:03:00.0:clpeak[2387]:2!
