Pull sysctl updates from Luis Chamberlain:
"For two kernel releases now kernel/sysctl.c has been being cleaned up
slowly, since the tables were grossly long, sprinkled with tons of
#ifdefs and all this caused merge conflicts with one susbystem or
another.
This tree was put together to help try to avoid conflicts with these
cleanups going on different trees at time. So nothing exciting on this
pull request, just cleanups.
Thanks a lot to the Uniontech and Huawei folks for doing some of this
nasty work"

This move the kernel/kexec_core.c respective sysctls to its own file.
kernel/sysctl.c has grown to an insane mess, We move sysctls to places
where features actually belong to improve the readability and reduce
merge conflicts. At the same time, the proc-sysctl maintainers can easily
care about the core logic other than the sysctl knobs added for some feature.
We already moved all filesystem sysctls out. This patch is part of the effort
to move kexec related sysctls out.

Ok so hopefully this is the last of it. 0day picked up a build
failure [0] when SYSCTL=y but DYNAMIC_FTRACE=n. This can be fixed
by just declaring an empty routine for the calls moved just
recently.

as a minimum to a proc handler is not used. So just move this under

One can enable dyanmic tracing but disable sysctls.
When this is doen we get the compile kernel warning:
CC kernel/trace/ftrace.o
kernel/trace/ftrace.c:3086:13: warning: ‘ftrace_shutdown_sysctl’ defined
but not used [-Wunused-function]
3086 | static void ftrace_shutdown_sysctl(void)

kernel/trace/ftrace.c:3068:13: warning: ‘ftrace_startup_sysctl’ defined
but not used [-Wunused-function]
3068 | static void ftrace_startup_sysctl(void)
When CONFIG_DYNAMIC_FTRACE=n the ftrace_startup_sysctl() and
routines ftrace_shutdown_sysctl() still compiles, so these
are actually more just used for when SYSCTL=y.
Fix this then by just moving these routines to when sysctls
are enabled.

When CONFIG_PM_SLEEP is not set, there is a warning that
qcom_ipcc_pm_resume() is unused:
drivers/mailbox/qcom-ipcc.c:258:12: error: 'qcom_ipcc_pm_resume' defined but not used [-Werror=unused-function]
258 | static int qcom_ipcc_pm_resume(struct device *dev)
| ^~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old
ones") reworked the PM_OPS macros to avoid this problem. Use
NOIRQ_SYSTEM_SLEEP_PM_OPS directly so that qcom_ipcc_pm_resume() always
appears to be used to the compiler, even though it will be dead code
eliminated in the !CONFIG_PM_SLEEP case.

This reverts commit c7dacf5b0f32957b24ef29df1207dc2cd8307743,
"mailbox: avoid timer start from callback"
The previous commit was reverted since it lead to a race that
caused the hrtimer to not be started at all. The check for
hrtimer_active() in msg_submit() will return true if the
callback function txdone_hrtimer() is currently running. This
function could return HRTIMER_NORESTART and then the timer
will not be restarted, and also msg_submit() will not start
the timer. This will lead to a message actually being submitted
but no timer will start to check for its compleation.
The original fix that added checking hrtimer_active() was added to
avoid a warning with hrtimer_forward. Looking in the kernel
another solution to avoid this warning is to check hrtimer_is_queued()
before calling hrtimer_forward_now() instead. This however requires a
lock so the timer is not started by msg_submit() inbetween this check
and the hrtimer_forward() call.

Enable logging of the pending interrupt that triggered device wakeup. This
logging information helps to debug IRQs that cause periodic device wakeups
by printing the detailed information of pending IPCC interrupts.
Scenario: Device wakeup caused by Modem crash
Logs:
qcom-ipcc mailbox: virq: 182 triggered client-id: 2; signal-id: 2
From the IPCC bindings it can further be understood that the client here is
IPCC_CLIENT_MPSS and the signal was IPCC_MPROC_SIGNAL_SMP2P.

Tegra234 supports sending/receiving 32-bit and 128-bit data over
a shared mailbox. Based on the data size to be used, clients need
to specify the type of shared mailbox in the device tree.
Add a macro for 128-bit shared mailbox. Mailbox clients can use this
macro as a flag in device tree to enable 128-bit data support for a
shared mailbox.

Consumer examples in the bindings of resource providers are trivial,
useless and duplicating code. Additionally the incomplete qcom,smp2p
example triggers DT schema warnings.
Cleanup the example by removing the consumer part and fixing the
indentation to DT schema convention.

Pull gpio updates from Bartosz Golaszewski:
"We have lots of small changes all over the place, but no huge reworks
or new drivers:
- use ioread()/iowrite() interfaces instead of raw inb()/outb() in
drivers
- make irqchips immutable due to the new warning popping up when
drivers try to modify the irqchip structures
- add new compatibles to dt-bindings for realtek-otto, renesas-rcar
and pca95xx
- add support for new models to gpio-rcar, gpio-pca953x &
gpio-realtek-otto
- allow parsing of GPIO hogs represented as children nodes of
gpio-uniphier
- define a set of common GPIO consumer strings in dt-bindings
- shrink code in gpio-ml-ioh by using more devres interfaces
- pass arguments to devm_kcalloc() in correct order in gpio-sim
- add new helpers for iterating over GPIO firmware nodes and
descriptors to gpiolib core and use it in several drivers
- drop unused syscon_regmap_lookup_by_compatible() function
- correct format specifiers and signedness of variables in GPIO ACPI
- drop unneeded error checks in gpio-ftgpio
- stop using the deprecated of_gpio.h header in gpio-zevio
- drop platform_data support in gpio-max732x
- simplify Kconfig dependencies in gpio-vf610
- use raw spinlocks where needed to make PREEMPT_RT happy
- fix return values in board files using gpio-pcf857x
- convert more drivers to using fwnode instead of of_node
- minor fixes and improvements in gpiolib core"

Commit 6c846d026d49 ("gpio: Don't fiddle with irqchips marked as
immutable") added a warning to indicate if the gpiolib is altering the
internals of irqchips. Following this change the following warning is
now observed for the sifive driver:
gpio gpiochip1: (38001000.gpio-controller): not an immutable chip, please consider fixing it!
Fix this by making the irqchip in the sifive driver immutable.
