SA replay mode is initialized differently for user-space and

common path with boolean protection. That caused to situation where

Firmware contants do not fit the purpose of bindings because they are not
independent IDs for abstractions. They are more or less just contants which
better to wire via header with DT which is using it.
That's why add deprecated message to dt binding header and also update
existing dt bindings not to use macros from the header and replace them by
it's value. Actually value is not relevant because it is only example.

Prior to commit 70c90e4a6b ("perf parse-events: Avoid scanning PMUs
before parsing") names (generally event names) excluded hyphen (minus)
symbols as the formation of legacy names with hyphens was handled in
the yacc code. That commit allowed hyphens supposedly making
name_minus unnecessary. However, changing name_minus to name has
issues in the term config tokens as then name ends up having priority
over numbers and name allows matching numbers since commit
5ceb57990b ("perf parse: Allow tracepoint names to start with digits
"). It is also permissable for a name to match with a colon (':') in
it when its in a config term list. To address this rename name_minus
to term_name, make the pattern match name's except for the colon, add
number matching into the config term region with a higher priority
than name matching. This addresses an inconsistency and allows greater
matching for names inside of term lists, for example, they may start
with a number.
Rename name_tag to quoted_name and update comments and helper
functions to avoid str detecting quoted strings which was already done
by the lexer.

Instead of only two frequencies, if OPP V2 is used, the UFS devfreq clock
scaling may scale the clock among multiple frequencies. In the case of
scaling up, the devfreq may decide to scale the clock to an intermediate
freq based on load, but the clock scale up pre change operation uses
settings for the max clock freq unconditionally. Fix it by passing the
target_freq to clock scale up pre change so that the correct settings for
the target_freq can be used.
In the case of scaling down, the clock scale down post change operation is
doing fine, because it reads the actual clock rate to tell freq, but to
keep symmetry with clock scale up pre change operation, just use the
target_freq instead of reading clock rate.

bpf_send_signal_common() uses preemptible() to check whether or not the
current context is preemptible. If it is preemptible, it will use
irq_work to send the signal asynchronously instead of trying to hold a
spin-lock, because spin-lock is sleepable under PREEMPT_RT.
However, preemptible() depends on CONFIG_PREEMPT_COUNT. When
CONFIG_PREEMPT_COUNT is turned off (e.g., CONFIG_PREEMPT_VOLUNTARY=y),
!preemptible() will be evaluated as 1 and bpf_send_signal_common() will
use irq_work unconditionally.

drivers. But it missed the fact that the levels could be initialized to 0
(UFS_PM_LVL_0) on purpose by the controller drivers. Even though none of
the drivers are doing so now, the logic should be fixed irrespectively.
So set the default levels unconditionally before calling ufshcd_hba_init()
API which initializes the controller drivers. It ensures that the
controller drivers could override the default levels if required.

This function translates the rate number reported by the hardware into
something mac80211 can understand. It was ignoring the 3SS and 4SS HT
rates. Translate them too.
Also set *nss to 0 for the HT rates, just to make sure it's
initialised.

rtw_mac_power_switch() checks bit 8 of REG_SYS_STATUS1 to see if the
chip is powered on. This bit appears to be always on in the RTL8814AU,
so ignore it.

selftests: drv-net: improve the queue test for XSK
We see some flakes in the the XSK test:
Exception| Traceback (most recent call last):
Exception| File "/home/virtme/testing-18/tools/testing/selftests/net/lib/py/ksft.py", line 218, in ksft_run
Exception| case(*args)
Exception| File "/home/virtme/testing-18/tools/testing/selftests/drivers/net/./queues.py", line 53, in check_xdp
Exception| ksft_eq(q['xsk'], {})
Exception| KeyError: 'xsk'
I think it's because the method of running the helper in the background
is racy. Add more solid infra for waiting for a background helper to be
initialized.

The test is for AF_XDP, we refer to AF_XDP as XSK.

Avoid exceptions when xsk attr is not present, and add a proper ksft
helper for "not in" condition.

We use wait_port_listen() extensively to wait for a process
we spawned to be ready. Not all processes will open listening
sockets. Add a method of explicitly waiting for a child to
be ready. Pass a FD to the spawned process and wait for it
to write a message to us. FD number is passed via KSFT_READY_FD
env variable.
Similarly use KSFT_WAIT_FD to let the child process for a sign
that we are done and child should exit. Sending a signal to
a child with shell=True can get tricky.
Make use of this method in the queues test to make it less flaky.

Separate the support check from socket binding for easier refactoring.
Use: ./helper - - just to probe if we can open the socket.
