sched/cputime: Don't warn when the tick period starts after idle exit
kcpustat_dyntick_stop() warns if idle ends before the tick period
that the next tick will account has started. That happens on x86 in
a CPU's first idle period with the tick stopped, right after the
switch from the jiffies clocksource to tsc-early.
On the jiffies clocksource ktime only moves at the tick. When the
clocksource switches some time d after a tick, that d is lost: ktime
continues from the value of the last tick. The next tick comes
TICK_NSEC after the last one, but ktime has only moved TICK_NSEC - d,
while tick_periodic() still adds a full TICK_NSEC to tick_next_period,
which is now d ahead of ktime. When NOHZ starts,
tick_init_jiffy_update() rounds it up to a multiple of TICK_NSEC and
the sched timer is armed there, up to nearly two ticks after now. A
tick stop saves that as ts->last_tick, and an idle exit before now
reaches ts->last_tick - TICK_NSEC sees the tick period in the future.
Nothing is accounted twice then. The first tick covers a period that
starts after the idle exit, and the code already handles it. Drop the
warning.

sound fixes for 7.4-rc1
A collection of fixes across the sound subsystem since the initial
7.4 PR. Nothing particularly stands out, mostly driver- and
device-specific fixes along with a few race / UAF fixes and cleanups.
Here are some highlights:
* ALSA core:
- Fix potential race in PCM proc handling at disconnection
- Fix potential race in UMP sequencer callback at releasing
* HD-audio:
- Reject codec reset/reconfig on ASoC buses to prevent deadlock
- Force MSI for Hygon H34M51A board
- Usual Realtek quirks for ASUS and HP laptops/AiO
* USB-audio:
- Bound packet copies by PCM buffer size in generic and ua101 drivers
- Rate-limit URB submission errors at stream start
- Skip redundant probe-time interface setup on MSI ALC4080
- Device quirks for Novation UltraNova, MOTU MicroBook II, and RYDZ
Headphone
* ASoC:
- Fixes for runtime PM and IRQ handling in hdac_hda and SDCA
- SOF: Fix potential UAF at release, fix for Kconfig dependency
- Qualcomm: Fixes for sm8250 and q6apm/q6afe
- NXP / i.MX: Fix for pending work in hw_free
- Xilinx: Fix read-modify-write of AUD_CTRL in formatter_pcm
- Intel: Arrow Lake SoundWire match table additions (RT712, RT713 +
dual RT1320)
- AMD: DMI quirk for HP Laptop 14-em0xxx and memory leak fix in Raven
DMA close
- Various codec fixes for midas_wm1811, wm8994, cs35l56, cs42l56,
WSA881x/883x/884x, es8326/es8375/es9356, rt721/rt722, and
tlv320aic32x4
* Misc:
- OPL3: Fix races in timer initialization, shutdown, and voice cleanup
- Bounds checks and string helpers for AC97 and emu10k1
- Fix spu_memset() stride in legacy SH AICA driver

tools/power turbostat: Fix undefined behavior in pmt_gen_value_mask()
The function uses plain int literal '1' for bit shifting, which causes undefined behavior when msb >= 31. This is because shifting a 32-bit int by 32 or more bits is undefined behavior in C. Fix by using 1ULL (unsigned long long) instead of 1 to ensure 64-bit arithmetic on all platforms.

init/bootconfig: pass init arguments in documented order
start_kernel() appends command-line init arguments before
bootconfig init arguments, while setup_command_line()
places them in the opposite order. As a result, the
arguments passed to init do not match the saved command
line, reversing the intended precedence of options.
Parse extra_init_args before after_dashes so command-line
init arguments are passed last.

- Fix compound CREATE response buffer sizing and reserve space for final
response padding to prevent buffer overflows and out-of-bounds reads.
- Allocate sufficient space for UTF-16 directory-name conversion,
including the terminating NUL.
- Fix an RDMA transfer length underflow that can cause out-of-bounds
reads or writes when processing multiple remote buffer descriptors.
- Fix use-after-free bugs during failed durable reconnect cleanup and
AppInstanceId supersede racing with session teardown.
- Keep retry timeout clamp bounds constant to fix a MIPS build
failure with CONFIG_HZ=1024.
- Fix a session reference leak in compounded SESSION_SETUP and reject
compounded session binding to avoid mixing session and tree state
after a failed binding.
- Serialize operations on each named pipe and preserve unread RPC reply
data for subsequent READ requests when the client's output buffer is
too small.
- Return complete, eight-byte-aligned stream information entries and
report insufficient output space correctly.
- Use the resolved share root path so shares rooted at mount points
list their contents correctly with crossmnt disabled.
- Ignore network-device events outside the initial network namespace,
preventing container interfaces from affecting ksmbd listeners.

ktest updates for v7.4:
- Sort configs before writing config file Currently the .config file is created from the perl hash array from reading the applied min-configs. The order is determined by how perl hashes the values. This causes the .config file to be created in different orders for each run, and the order may determine the final value of the .config file after it goes through a make oldconfig. Sort the values when creating the .config so that the result is the same for every run. - Add total test time to run output Have ktest display the total test time of running all the tests. This is useful to find issues in the build, install, boot or test run where things are hanging for longer than expected. - Update reading of the git output during bisect The ktest bisect is an automated way to run git bisect. Since there currently no easy way to know if the bisect found the bad commit (I'm talking with the git maintainers to fix this[1]), it parses the output for the line "is first bad commit". But a recent update to git has the output state "is the first 'bad' commit" which breaks ktest bisect. Have ktest handle both output strings.

- Validate the offsets and lengths a server puts in its responses before
using them, so that a malicious or broken server can no longer make the
client read past the received data: POSIX lock data (which leaked
kernel bytes through F_GETLK), NT transaction responses and SMB1 EA
lists (both wrapping their pointer checks on 32-bit), short
SESSION_SETUP responses (which sent stale buffer content back to the
server in the NTLMv2 AUTHENTICATE message), SMB2 READ data areas and
empty truncated fiemap responses
- Fix a heap overflow in SMB2_tcon() with UNC paths longer than
MAX_SHARENAME_LENGTH
- Fix a slab-out-of-bounds write when chmod() rewrites a security
descriptor that needs more room than was reserved
- Fix a use-after-free of the server info between the cifsd thread and
the release of the last session reference (reported by syzbot)
- Fix a use-after-free in the demultiplex thread when a receive error
reconnects and frees the read request still being processed
- Fix a double teardown of a tcon that the cached directory laundromat

Merge tag 'acpi-7.4-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI support fixes from Rafael Wysocki:
"These address assorted issues in ACPI support code and work around
concurrency-related issues in AML on some platforms:
- Separate handler locking from sysfs lifetime in the ACPI platform
profile driver to avoid possible deadlocks due to sysfs accesses
during driver removal (Daniel Lezcano)
- Introduce additional locking around the evaluation of selected ACPI
control methods in a few places to work around issues related to
concurrency in AML on some platforms (Ali Ahmet Memiş)
- Address two issues reported by Sashiko in the ACPI table data sysfs
interface (Jamie Nguyen)
- Initialize parser_state.aml_end in acpi_install_method() properly
to avoid out-of-bounds accesses during control method installation
(Ivan Hu)"

rtc: ds1685: keep setting PAB until power is removed
A kickstart or wake-up flag set while its interrupt is enabled (KF with KSE, WF with WIE) clears PAB, and the system stays powered. Clear the event flags together with setting PAB, and repeat the write until power is gone.

rtc: ds1685: arm the wake-up alarm at power-off only if an alarm is set
ds1685_rtc_poweroff() always sets WIE. The wake-up alarm then compares
the time-of-day and date alarm registers, which hold whatever was last
written to them, and a match powers the machine straight back on.
Set WIE only when AIE is set in Control B, and clear it otherwise.
