fdt_check_header(__dtb_start) will always success because kernel
provides a dummy dtb, and by coincidence __dtb_start clashed with
entry of this dummy dtb. The consequence is fdt passed from firmware
will never be taken.
Fix by trying to utilise __dtb_start only when CONFIG_BUILTIN_DTB is
enabled.

Both acpi_table_upgrade() and acpi_boot_table_init() are defined as
empty functions under !CONFIG_ACPI_TABLE_UPGRADE and !CONFIG_ACPI in
include/linux/acpi.h, there are no implicit declaration errors with
various configs.
#ifdef CONFIG_ACPI_TABLE_UPGRADE
void acpi_table_upgrade(void);
#else
static inline void acpi_table_upgrade(void) { }
#endif
#ifdef CONFIG_ACPI
...
void acpi_boot_table_init (void);
...
#else /* !CONFIG_ACPI */
...
static inline void acpi_boot_table_init(void)
{
}
...
#endif /* !CONFIG_ACPI */
As Huacai suggested, CONFIG_ACPI_TABLE_UPGRADE is ugly and not necessary
here, just remove it. At the same time, just keep CONFIG_ACPI to prevent
potential build errors in future, and give a signal to indicate the code
is ACPI-specific. For the same reason, we also put acpi_table_upgrade()
under CONFIG_ACPI.

git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
Removed the SPD class of i2c devices from the device core.
Additionally, a cleanup in the Synquacer code removes the pclk
from the global structure, as it is used only in the probe.
Therefore, it is now declared locally.

Pull ata fixes from Niklas Cassel:
- Add a quirk for three different devices that have shown issues with
LPM (link power management). These devices appear to not implement
LPM properly, since we see command timeouts when enabling LPM. The
quirk disables LPM for these problematic devices. (Me)
- Do not apply the Intel PCS quirk on Alder Lake. The quirk is not
needed and was originally added by mistake when LPM support was
enabled for this AHCI controller. Enabling the quirk when not needed
causes the the controller to not be able to detect the connected
devices on some platforms.

Currently NCSI driver will send several NCSI commands back to back without
waiting the response of previous NCSI command or timeout in some state
when NIC have multi channel. This operation against the single thread
manner defined by NCSI SPEC(section 6.3.2.3 in DSP0222_1.1.1)
According to NCSI SPEC(section 6.2.13.1 in DSP0222_1.1.1), we should probe
one channel at a time by sending NCSI commands (Clear initial state, Get
version ID, Get capabilities...), than repeat this steps until the max
number of channels which we got from NCSI command (Get capabilities) has
been probed.

When releasing a socket in ax25_release(), we call netdev_put() to
decrease the refcount on the associated ax.25 device. However, the
execution path for accepting an incoming connection never calls
netdev_hold(). This imbalance leads to refcount errors, and ultimately
to kernel crashes.
A typical call trace for the above situation will start with one of the
following errors:
refcount_t: decrement hit 0; leaking memory.
refcount_t: underflow; use-after-free.
And will then have a trace like:
Call Trace:

On reboot (or any attempt to remove the interface), the kernel gets
stuck in an infinite loop:
unregister_netdevice: waiting for ax0 to become free. Usage count = 0
This patch corrects these issues by ensuring that we call netdev_hold()
and ax25_dev_hold() for new connections in ax25_accept(). This makes the
logic leading to ax25_accept() match the logic for ax25_bind(): in both
cases we increment the refcount, which is ultimately decremented in
ax25_release().

When the following snippet is run, lockdep will report a deadlock[1].
/* Acquire all queues dim_locks */
for (i = 0; i < vi->max_queue_pairs; i++)
mutex_lock(&vi->rq[i].dim_lock);
There's no deadlock here because the vq locks are always taken
in the same order, but lockdep can not figure it out. So refactoring
the code to alleviate the problem.

When the dim worker is scheduled, if it no longer needs to issue
commands, dim may not be able to return to the working state later.
For example, the following single queue scenario:
1. The dim worker of rxq0 is scheduled, and the dim status is
changed to DIM_APPLY_NEW_PROFILE;
2. dim is disabled or parameters have not been modified;
3. virtnet_rx_dim_work exits directly;
Then, even if net_dim is invoked again, it cannot work because the
state is not restored to DIM_START_MEASURE.

because the request is marked forced ASYNC and has a bad file fd, and
hence takes the forced async prep path.
Current kernels with the request async prep cleaned up can no longer hit
this issue, but for ease of backporting, let's add this safety check in
here too as it really doesn't hurt. For both cases, this will inevitably
end with a CQE posted with -EBADF.

Since commit 0a44dfc07074 ("wifi: mac80211: simplify non-chanctx
drivers") ieee80211_hw_config() is no longer called with changed = ~0.
rtlwifi relied on ~0 in order to ignore the default retry limits of
4/7, preferring 48/48 in station mode and 7/7 in AP/IBSS.
RTL8192DU has a lot of packet loss with the default limits from
mac80211. Fix it by ignoring IEEE80211_CONF_CHANGE_RETRY_LIMITS
completely, because it's the simplest solution.

Commit f236464f1db7 ("wifi: wilc1000: convert list management to RCU")
attempted to convert SRCU to RCU usage, assuming it was not really needed.
The runtime issues that arose after merging it showed that there are code
paths involving sleeping functions, and removing those would need some
heavier driver rework.
Add some documentation about SRCU need to make sure that any future
developer do not miss some use cases if tempted to convert back again to
RCU.

This reverts commit 35aee01ff43d7eb6c2caa0b94e7cc6c45baeeab7
Commit 35aee01ff43d ("wifi: wilc1000: set atomic flag on kmemdup in srcu
critical section") was preparatory to the SRCU to RCU conversion done by
commit f236464f1db7 ("wifi: wilc1000: convert list management to RCU").
This conversion brought issues and so has been reverted, so the atomic flag
is not needed anymore.

This reverts commit f236464f1db7bea80075e6e31ac70dc6eb80547f
Commit f236464f1db7 ("wifi: wilc1000: convert list management to RCU")
replaced SRCU with RCU, aiming to simplify RCU usage in the driver. No
documentation or commit history hinted about why SRCU has been preferred
in original design, so it has been assumed to be safe to do this
conversion.
Unfortunately, some static analyzers raised warnings, confirmed by runtime
checker, not long after the merge. At least three different issues arose
when switching to RCU:
- wilc_wlan_txq_filter_dup_tcp_ack is executed in a RCU read critical
section yet calls wait_for_completion_timeout
- wilc_wfi_init_mon_interface calls kmalloc and register_netdevice while
manipulating a vif retrieved from vif list
- set_channel sends command to chip (and so, also waits for a completion)
while holding a vif retrieved from vif list (so, in RCU read critical
section)
Some of those issues are not trivial to fix and would need bigger driver
rework. Fix those issues by reverting the SRCU to RCU conversion commit

Turns out this breaks many architectures as the vt ioctls do not all

The bpf_session_cookie is unavailable for !CONFIG_FPROBE as reported
by Sebastian [1].
To fix that we remove CONFIG_FPROBE ifdef for session kfuncs, which
is fine, because there's filter for session programs.
Then based on bpf_trace.o dependency:
obj-$(CONFIG_BPF_EVENTS) += bpf_trace.o
we add bpf_session_cookie BTF_ID in special_kfunc_set list dependency
on CONFIG_BPF_EVENTS.

When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang issues this warning:
futex_requeue_pi.c:403:17: warning: passing 'const char **' to parameter
of type 'char **' discards qualifiers in nested pointer types
[-Wincompatible-pointer-types-discards-qualifiers]
This warning fires because test_name is passed into asprintf(3), which
then changes it.
Fix this by simply removing the const qualifier. This is a local
automatic variable in a very short function, so there is not much need
to use the compiler to enforce const-ness at this scope.
