clocksource/drivers/sh_cmt: Split start/stop of clock source and events
The CMT do a housekeeping such as dealing with runtime PM and
enable/disable clocks when either a clock source is enabled, or when a
new clock event is registered.
Doing this type of housekeeping for when a clock event is registered is
not always possible as it can happen in contexts where holding spinlocks
is not possible. However doing it when registering a clock source is
possible.
As a first step to address this design break apart the CMT start and
stop functions. The path for clock sources need not change, while the
one for clock events need to be reworked in future work.
There is no indented functional change, just breaking the two use-cases
controlled by a flag into two distinct functions.

clocksource/drivers/arm_global_timer: Add auto-detection for initial prescaler values
am43xx has a clock tree where the global timer clock is an indirect child
of the CPU clock used for frequency scaling:
dpll_mpu_ck -- CPU/cpufreq
|
v
dpll_mpu_m2_ck -- divider
|
v
mpu_periphclk -- fixed divider by 2 used for global timer
When CPU frequency changes, the global timer's clock notifier rejects
the change because the hardcoded prescaler (1 or 2) cannot accommodate
the frequency range across all CPU OPPs (300, 600, 720, 800, 1000 MHz).
Add platform-specific prescaler auto-detection to solve this issue:
- am43xx: prescaler = 50 (calculated as initial_freq/GCD of all OPP
freqs) This allows the timer to work across all CPU frequencies after
the fixed divider by 2. Tested on am4372-idk-evm.
- Other platforms: prescaler = 1 (previous default)
The Kconfig option now defaults to 0 (auto-detection) but can still
override the auto-detected value when set to a non-zero value,
preserving existing customization workflows.

clocksource/drivers/timer-rtl-otto: Do not interfere with interrupts
During normal operation the timers are reprogrammed including an
interrupt acknowledgement. This has no effect as the whole timer
is setup from scratch afterwards. Especially in an interrupt this
has already been done by rttm_timer_interrupt().
Change the behaviour as follows:
- Use rttm_disable_timer() during reprogramming
- Keep rttm_stop_timer() for all other use cases.

clocksource/drivers/timer-rtl-otto: Work around dying timers
The OpenWrt distribution has switched from kernel longterm 6.6 to
6.12. Reports show that devices with the Realtek Otto switch platform
die during operation and are rebooted by the watchdog. Sorting out
other possible reasons the Otto timer is to blame. The platform
currently consists of 4 targets with different hardware revisions.
It is not 100% clear which devices and revisions are affected.
Analysis shows:
A more aggressive sched/deadline handling leads to more timer starts
with small intervals. This increases the bug chances. See
https://marc.info/?l=linux-kernel&m=175276556023276&w=2
Focusing on the real issue a hardware limitation on some devices was
found. There is a minimal chance that a timer ends without firing an
interrupt if it is reprogrammed within the 5us before its expiration
time. Work around this issue by introducing a bounce() function. It
restarts the timer directly before the normal restart functions as
follows:
- Stop timer
- Restart timer with a slow frequency.
- Target time will be >5us
- The subsequent normal restart is outside the critical window

clocksource/drivers/nxp-pit: Add NXP Automotive s32g2 / s32g3 support
The previous changes put in place the encapsulation of the code in
order to allow multiple instances of the driver.
The S32G platform has two Periodic Interrupt Timer (PIT). The IP is
exactly the same as the VF platform.
Each PIT has four channels which are 32 bits wide and counting
down. The two first channels can be chained to implement a 64 bits
counter. The channel usage is kept unchanged with the original driver,
channel 2 is used as a clocksource, channel 3 is used as a
clockevent. Other channels are unused.
In order to support the S32G platform which has two PIT, we initialize
the timer and bind it to a CPU. The S32G platforms can have 2, 4 or 8
CPUs and this kind of configuration can appear unusual as we may endup
with two PIT used as a clockevent for the two first CPUs while the
other CPUs use the architected timers. However, in the context of the
automotive, the platform can be partioned to assign 2 CPUs for Linux
and the others CPUs to third party OS. The PIT is then used with their
specifities like the ability to freeze the time which is needed for
instance for debugging purpose.
The setup found for this platform is each timer instance is bound to
CPU0 and CPU1.
A counter is incremented when a timer is successfully initialized and
assigned to a CPU. This counter is used as an index for the CPU number
and to detect when we reach the maximum possible instances for the
platform. That in turn triggers the CPU hotplug callbacks to achieve
the per CPU setup. It is the exact same mechanism found in the NXP STM
driver.
If the timers must be bound to different CPUs, it would require an
additionnal mechanism which is not part of these changes.

Leverage the the CPU_SET(3) macros to break this barrier.
Also, break the Joules & Watts counters into two,

io_uring/memmap: cast nr_pages to size_t before shifting
If the allocated size exceeds UINT_MAX, then it's necessary to cast
the mr->nr_pages value to size_t to prevent it from overflowing. In
practice this isn't much of a concern as the required memory size will
have been validated upfront, and accounted to the user. And > 4GB sizes
will be necessary to make the lack of a cast a problem, which greatly
exceeds normal user locked_vm settings that are generally in the kb to
mb range. However, if root is used, then accounting isn't done, and
then it's possible to hit this issue.

mailbox/pcc: support mailbox management of the shared buffer
Define a new, optional, callback that allows the driver to
specify how the return data buffer is allocated. If that callback
is set, mailbox/pcc.c is now responsible for reading from and
writing to the PCC shared buffer.
This also allows for proper checks of the Commnand complete flag
between the PCC sender and receiver.
For Type 4 channels, initialize the command complete flag prior
to accepting messages.
Since the mailbox does not know what memory allocation scheme
to use for response messages, the client now has an optional
callback that allows it to allocate the buffer for a response
message.
When an outbound message is written to the buffer, the mailbox
checks for the flag indicating the client wants an tx complete
notification via IRQ. Upon receipt of the interrupt It will
pair it with the outgoing message. The expected use is to
free the kernel memory buffer for the previous outgoing message.

Pull more s390 updates from Alexander Gordeev:
- Support MMIO read/write tracing
- Enable THP swapping and THP migration
- Unmask SLCF bit ("stateless command filtering") introduced with CEX8
cards, so that user space applications like lszcrypt could evaluate
and list this feature
- Fix the value of high_memory variable, so it considers possible
tailing offline memory blocks
- Make vmem_pte_alloc() consistent and always allocate memory of
PAGE_SIZE for page tables. This ensures a page table occupies the
whole page, as the rest of the code assumes
- Fix kernel image end address in the decompressor debug output
- Fix a typo in debug_sprintf_format_fn() comment

smb: server: Fix extension string in ksmbd_extract_shortname()
In ksmbd_extract_shortname(), strscpy() is incorrectly called with the
length of the source string (excluding the NUL terminator) rather than
the size of the destination buffer. This results in "__" being copied
to 'extension' rather than "___" (two underscores instead of three).
Use the destination buffer size instead to ensure that the string "___"
(three underscores) is copied correctly.
