Provide common prototypes for arch_register_cpu() and
arch_unregister_cpu(). These are called by acpi_processor.c, with weak
versions, so the prototype for this is already set. It is generally not
necessary for function prototypes to be conditional on preprocessor macros.
Some architectures (e.g. Loongarch) are missing the prototype for this, and
rather than add it to Loongarch's asm/cpu.h, do the job once for everyone.
Since this covers everyone, remove the now unnecessary prototypes in
asm/cpu.h, and therefore remove the 'static' from one of ia64's
arch_register_cpu() definitions.

Add void *context arrgument to the list of arguments of
acpi_dev_install_notify_handler() and modify it to pass that argument
as context to acpi_install_notify_handler() instead of its first
argument which is problematic in general (for example, if platform
drivers used it, they would rather get struct platform_device pointers
or pointers to their private data from the context arguments of their
notify handlers).
Make all of the current callers of acpi_dev_install_notify_handler()
take this change into account so as to avoid altering the general
functionality.

Address a long-standing "TBD" comment in the ACPI headers regarding the
number of handles in struct acpi_handle_list.
The number 10, which along with the comment dates back to 2.4.23, seems
like it may have been arbitrarily chosen and isn't sufficient in all
cases [1].
Finally change the code to dynamically determine the size of the handles
table in struct acpi_handle_list and allocate it accordingly.
Update the users of to struct acpi_handle_list to take the additional
dynamic allocation into account.

ghes_handle_aer() passes AER data to the PCI core for logging and
recovery by calling aer_recover_queue() with a pointer to struct
aer_capability_regs.
The problem was that aer_recover_queue() queues the pointer directly
without copying the aer_capability_regs data. The pointer was to
the ghes->estatus buffer, which could be reused before
aer_recover_work_func() reads the data.
To avoid this problem, allocate a new aer_capability_regs structure
from the ghes_estatus_pool, copy the AER data from the ghes->estatus
buffer into it, pass a pointer to the new struct to
aer_recover_queue(), and free it after aer_recover_work_func() has
processed it.

Currently, the SystemCMOS address space handler is installed for the
ACPI RTC devices (PNP0B00/PNP0B01/PNP0B02) only. But there are platforms
with SystemCMOS Operetion Region defined under the ACPI Time and Alarm
Device (ACPI000E), which is used by the ACPI pre-defined control methods
like _GRT (Get the Real time) and _SRT (Set the Real time).
When accessing these control methods via the acpi_tad sysfs interface,
missing SystemCMOS address space handler causes errors like below
[ 478.255453] ACPI Error: No handler for Region [RTCM] (00000000a8d2dd39) [SystemCMOS] (20230331/evregion-130)

Introduce new functions acpi_dev_install_notify_handler() and
acpi_dev_remove_notify_handler(), to install and remove, respectively,
a handler for AML Notify() operations targeted at a given ACPI device
object. They will allow drivers to install Notify() handlers directly
instead of providing an ACPI driver .notify() callback to be invoked
in the context of a Notify() handler installed by the ACPI bus type
code. In particular, this will help platform drivers to provide
Notify() handlers for the ACPI companions of the platform devices
they bind to.
These functions are replacements for acpi_device_install_notify_handler()
and acpi_device_remove_notify_handler(), respectively, and after all
drivers switch over to using them, the old ones will be dropped.

The processor _OSC method is already used for a workaround introduced
in commit a21211672c9a ("ACPI / processor: Request native thermal
interrupt handling via _OSC"), but in accordance with ACPI 6.5 (and
earlier), it should be used for negotiating all of the processor
capabilities instead of _PDC (which has been deprecated since ACPI 3.0
and got removed from ACPI 6.5 entirely).
Create a new callback function called acpi_processor_osc() to be invoked
for every processor object and processor device in the ACPI namespace, in
analogy with the already existing acpi_hwp_native_thermal_lvt_osc().
Make this function implement the workaround mentioned above and convey
all of the OSPM processor support information to the platform firmware
by setting all of the appropriate processor capabilities bits before
evaluating _OSC for the given processor. For this purpose, make it
call arch_acpi_set_proc_cap_bits() and modify the latter to set
ACPI_PROC_CAP_COLLAB_PROC_PERF along with the other processor
capabilities bits.

The prefix in the names of the ACPI_PDC symbols suggests that they are
only relevant for _PDC, but in fact they can also be used in the _OSC.
Change that prefix to a more generic ACPI_PROC_CAP that will better
reflect the purpose of those symbols as they represent bits in a general
processor capabilities buffer.
Rename pdc_intel.h to proc_cap_intel.h to follow the change of the
symbol name prefix.
No intentional functional impact.

ACPICA commit 8c048cee4ea7b9ded8db3e1b3b9c14e21e084a2c
This adds 3 different external interrupt controller
definitions in MADT for RISC-V.
1) RISC-V PLIC is a platform interrupt controller for
handling wired interrupt in a RISC-V systems.
2) RISC-V IMSIC is MSI interrupt controller to
support MSI interrupts.
3) RISC-V APLIC has dual functionality. First it can
act like PLIC and direct all wired interrupts to
the CPU which doesn't have MSI controller. Second,
when the CPU has MSI controller (IMSIC), it will
act as a converter from wired interrupts to MSI.
Update the existing RINTC structure also to support
these external interrupt controllers.
This codefirst ECR is approved by UEFI forum and will
be part of next ACPI spec version.

ACPICA commit aea0a5cfce262ce2ab16fd96d87c12cf5e756380
We're storing a persistent pointer to an ephemeral local variable
which technically is a dangling pointer and the compiler is correct.
However, since we never indirect the pointer, this is a safe
operation and we can suppress the warning.
Also, some C run-times (like MUSL) aren't including <stdint.h>
indirectly so we must include it explicitly or we won't have the
type definition for uintptr_t.
Fixes issue #867.

Pull hardening updates from Kees Cook:
"There are three areas of note:
A bunch of strlcpy()->strscpy() conversions ended up living in my tree
since they were either Acked by maintainers for me to carry, or got
ignored for multiple weeks (and were trivial changes).
The compiler option '-fstrict-flex-arrays=3' has been enabled
globally, and has been in -next for the entire devel cycle. This
changes compiler diagnostics (though mainly just -Warray-bounds which
is disabled) and potential UBSAN_BOUNDS and FORTIFY _warning_
coverage. In other words, there are no new restrictions, just
potentially new warnings. Any new FORTIFY warnings we've seen have
been fixed (usually in their respective subsystem trees). For more
details, see commit df8fc4e934c12b.
The under-development compiler attribute __counted_by has been added
so that we can start annotating flexible array members with their
associated structure member that tracks the count of flexible array
elements at run-time. It is possible (likely?) that the exact syntax
of the attribute will change before it is finalized, but GCC and Clang
are working together to sort it out. Any changes can be made to the
macro while we continue to add annotations.
As an example of that last case, I have a treewide commit waiting with
such annotations found via Coccinelle:
https://git.kernel.org/linus/adc5b3cb48a049563dc673f348eab7b6beba8a9b
Also see commit dd06e72e68bcb4 for more details.

- Fix strscpy() kerndoc typo (Arne Welzel)

- Add KUnit tests for strcat()-family
- Enable KUnit tests of FORTIFY wrappers under UML

The addition of might_sleep() to down_timeout() caused the latter to
enable interrupts unconditionally in some cases, which in turn broke
the ACPI S3 wakeup path in acpi_suspend_enter(), where down_timeout()
is called by acpi_disable_all_gpes() via acpi_ut_acquire_mutex().
Namely, if CONFIG_DEBUG_ATOMIC_SLEEP is set, might_sleep() causes
might_resched() to be used and if CONFIG_PREEMPT_VOLUNTARY is set,
this triggers __cond_resched() which may call preempt_schedule_common(),
so __schedule() gets invoked and it ends up with enabled interrupts (in
the prev == next case).
Now, enabling interrupts early in the S3 wakeup path causes the kernel
to crash.
Address this by modifying acpi_suspend_enter() to disable GPEs without
attempting to acquire the sleeping lock which is not needed in that code
path anyway.

Notice that all of the objects for which the acpi_scan_check_dep()
return value is greater than 0 are present in acpi_dep_list as consumers
(there may be multiple entries for one object, but that is not a
problem), so after carrying out the initial ACPI namespace walk in which
devices with dependencies are skipped, acpi_bus_scan() can simply walk
acpi_dep_list and enumerate all of the unique consumer objects from
there and their descendants instead of walking the entire target branch
of the ACPI namespace and looking for device objects that have not been
enumerated yet in it.
Because walking acpi_dep_list is generally less overhead than walking
the entire ACPI namespace, use the observation above to reduce the
system initialization overhead related to ACPI, which is particularly
important on large systems.

acpi_video# backlight devices has been disabled by default.
The few bugreports where this option was used as a workaround were all
cases where the GPU driver did not call acpi_video_register_backlight()
and the workaround was to pass video.register_backlight_delay=1.
With the recent "ACPI: video: Make acpi_backlight=video work independent
from GPU driver" changes acpi_backlight=video can be used to achieve
the same result. So there is no need for the register_backlight_delay
option + code anymore.

ACPICA commit bfdd3446e7caf795c85c70326c137023942972c5
Similar to "Replace one-element array with flexible-array", replace the
1-element array with a proper flexible array member as defined by C99.
This allows the code to operate without tripping compile-time and run-
time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds,
and/or -fstrict-flex-arrays=3). Note that the spec requires there be at
least one interrupt, so use a union to keep space allocated for this.
The only binary change in .text and .data sections is some rearrangement
by the compiler of acpi_dm_address_common(), but appears to be harmless.

ACPICA commit e7f6d8c1b7f79eb4b9b07f1bc09c549a2acbd6e8
Use ACPI_FLEX_ARRAY() helper to define flexible array member alone in a
struct. Fixes issue #812.
No binary changes appear in the .text nor .data sections.
