Pull arm64 updates from Catalin Marinas:
"The biggest part is the virtual CPU hotplug that touches ACPI,
irqchip. We also have some GICv3 optimisation for pseudo-NMIs that has
been queued via the arm64 tree. Otherwise the usual perf updates,
kselftest, various small cleanups.
Core:
- Virtual CPU hotplug support for arm64 ACPI systems
- cpufeature infrastructure cleanups and making the FEAT_ECBHB ID
bits visible to guests
- CPU errata: expand the speculative SSBS workaround to more CPUs
- GICv3, use compile-time PMR values: optimise the way regular IRQs
are masked/unmasked when GICv3 pseudo-NMIs are used, removing the
need for a static key in fast paths by using a priority value
chosen dynamically at boot time
ACPI:
- 'acpi=nospcr' option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
Perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4
- Add missing PMU driver MODULE_DESCRIPTION() strings
- Hook up DT compatibles for recent CPU PMUs

- Kernel mode NEON fp-stress
- Cleanups, spelling mistakes
Miscellaneous:
- arm64 Documentation update with a minor clarification on TBI
- Fix missing IPI statistics

There's no real need for callers to resolve ops from a fwnode in order
to then pass both to iommu_fwspec_init() - it's simpler and more sensible
for that to resolve the ops itself. This in turn means we can centralise
the notion of checking for a present driver, and enforce that fwspecs
aren't allocated unless and until we know they will be usable.
Also use this opportunity to modernise with some "new" helpers that
arrived shortly after this code was first written; the generic
fwnode_handle_get() clears up that ugly get/put mismatch, while
of_fwnode_handle() can now abstract those open-coded dereferences.

struct acpi_scan_handler has a detach callback that is used to remove
a driver when a bus is changed. When interacting with an eject-request,
the detach callback is called before _EJ0.
This means the ACPI processor driver can't use _STA to determine if a
CPU has been made not-present, or some of the other _STA bits have been
changed. acpi_processor_remove() needs to know the value of _STA after
_EJ0 has been called.
Add a post_eject callback to struct acpi_scan_handler. This is called
after acpi_scan_hot_remove() has successfully called _EJ0. Because
acpi_scan_check_and_detach() also clears the handler pointer,
it needs to be told if the caller will go on to call
acpi_bus_post_eject(), so that acpi_device_clear_enumerated()
and clearing the handler pointer can be deferred.
An extra flag is added to flags field introduced in the previous
patch to achieve this.

Separate code paths, combined with a flag set in acpi_processor.c to
indicate a struct acpi_processor was for a hotplugged CPU ensured that
per CPU data was only set up the first time that a CPU was initialized.
This appears to be unnecessary as the paths can be combined by letting
the online logic also handle any CPUs online at the time of driver load.
Motivation for this change, beyond simplification, is that ARM64
virtual CPU HP uses the same code paths for hotplug and cold path in
acpi_processor.c so had no easy way to set the flag for hotplug only.
Removing this necessity will enable ARM64 vCPU HP to reuse the existing
code paths.

MADT Multiprocessor Wakeup structure version 1 brings support for CPU offlining:
BIOS provides a reset vector where the CPU has to jump to for offlining itself.
The new TEST mailbox command can be used to test whether the CPU offlined itself
which means the BIOS has control over the CPU and can online it again via the
ACPI MADT wakeup method.
Add CPU offlining support for the ACPI MADT wakeup method by implementing custom
cpu_die(), play_dead() and stop_this_cpu() SMP operations.
CPU offlining makes it possible to hand over secondary CPUs over kexec, not
limiting the second kernel to a single CPU.
The change conforms to the approved ACPI spec change proposal. See the Link.

In order to support MADT wakeup structure version 1, provide more appropriate
names for the fields in the structure.
Rename 'mailbox_version' to 'version'. This field signifies the version of the
structure and the related protocols, rather than the version of the mailbox.
This field has not been utilized in the code thus far.
Rename 'base_address' to 'mailbox_address' to clarify the kind of address it
represents. In version 1, the structure includes the reset vector address. Clear
and distinct naming helps to prevent any confusion.

After starting to install the EC address space handler at the ACPI
namespace root, if there is an "orphan" _REG method in the EC device's
scope, it will not be evaluated any more. This breaks EC operation
regions on some systems, like Asus gu605.
To address this, use a wrapper around an existing ACPICA function to
look for an "orphan" _REG method in the EC device scope and evaluate
it if present.
Fixes: 60fa6ae6e6d0 ("ACPI: EC: Install address space handler at the namespace root")
Closes: https://bugzilla.kernel.org/show_bug.cgi?id=218945

On Dell servers, many APCI methods of acpi_power_meter module evaluate
variables inside IPMI region, so the region handler needs to be
installed. In addition to that, the handler needs to be fully
functional, and that depends on SMI being selected.
So add a helper to let acpi_power_meter know when the handler is
installed and ready to be used.

Main goal of memory allocation profiling patchset is to provide accounting
that is cheap enough to run in production. To achieve that we inject
counters using codetags at the allocation call sites to account every time
allocation is made. This injection allows us to perform accounting
efficiently because injected counters are immediately available as opposed
to the alternative methods, such as using _RET_IP_, which would require
counter lookup and appropriate locking that makes accounting much more
expensive. This method requires all allocation functions to inject
separate counters at their call sites so that their callers can be
individually accounted. Counter injection is implemented by allocation
hooks which should wrap all allocation functions.
Inlined functions which perform allocations but do not use allocation
hooks are directly charged for the allocations they perform. In most
cases these functions are just specialized allocation wrappers used from
multiple places to allocate objects of a specific type. It would be more
useful to do the accounting at their call sites instead. Instrument these
helpers to do accounting at the call site. Simple inlined allocation
wrappers are converted directly into macros. More complex allocators or
allocators with documentation are converted into _noprof versions and
allocation hooks are added. This allows memory allocation profiling
mechanism to charge allocations to the callers of these functions.

Add support for ACPI RAS2 feature table(RAS2) defined in the ACPI 6.5
Specification & upwards revision, section 5.2.21.
The RAS2 table provides interfaces for platform RAS features. RAS2 offers
the same services as RASF, but is more scalable than the latter.
RAS2 supports independent RAS controls and capabilities for a given RAS
feature for multiple instances of the same component in a given system.
The platform can support either RAS2 or RASF but not both.

Commit b2b32a173881 ("ACPI: bus: update acpi_dev_hid_uid_match() to
support multiple types") added _UID matching support for both integer
and string types, which satisfies NULL @uid2 argument for string types
using inversion, but this logic prevents _UID comparision in case the
argument is integer 0, which may result in false positives.
Fix this using _Generic(), which will allow NULL @uid2 argument for
string types as well as _UID matching for all possible integer values.

Modules registering driver with acpi_bus_register_driver() often forget to
set .owner field. The field is used by some of other kernel parts for
reference counting (try_module_get()), so it is expected that drivers
will set it.
Solve the problem by moving this task away from the drivers to the core
ACPI bus code, just like we did for platform_driver in
commit 9447057eaff8 ("platform_device: use a macro instead of
platform_driver_register").

The table is composed of a range of endpoints with each describing
audio formats they support. Most of the operations involve iterating
over elements of the table and filtering them. Simplify the process by
implementing range of getters.
While the acpi_nhlt_endpoint_mic_count() stands out a bit, it is a
critical component for any AudioDSP driver to know how many digital
microphones it is dealing with.

ACPICA commit 32260f5ce519e854546ce907fc0cc449e1fe51fe
Non HDAudio Link Table (NHLT) is designed to separate hardware-related
description (registers) from AudioDSP firmware-related one i.e.:
pipelines and modules that together make up the audio stream on Intel
DSPs. This task is important as same set of hardware registers can be
used with different topologies and vice versa, same topology could be
utilized with different set of hardware. As the hardware registers
description is directly tied to specific platform, intention is to have
such description part of low-level firmware e.g.: BIOS.
The initial design has been provided in early Sky Lake (SKL) days. The
audio architecture goes by the name cAVS. SKL is a representative of
cAVS 1.5. The table helps describe endpoint capabilities ever since.
While Raptor Lake (RPL) is the last of cAVS architecture - cAVS 2.5 to
be precise - its successor, the ACE architecture which begun with
Meteor Lake (MTL) inherited the design for all I2S and PDM
configurations. These two configurations are the primary targets for
NHLT table.
Due to naming conflicts with existing code, several structs are named
'nhlt2' rather than 'nhlt'. Follow up changes clean this up once
existing code has no users and is removed.

CONFIG_X86_ANDROID_TABLETS
Some recent(ish) Dell AIO devices have a backlight controller board
connected to an UART.
This UART has a DELL0501 HID with CID set to PNP0501 so that the UART is
still handled by 8250_pnp.c. Unfortunately there is no separate ACPI device
with an UartSerialBusV2() resource to model the backlight-controller.
The next patch in this series will use acpi_quirk_skip_serdev_enumeration()
to still create a serdev for this for a backlight driver to bind to
instead of creating a /dev/ttyS0.
This new acpi_quirk_skip_serdev_enumeration() use is not limited to Android
X86 tablets, so move it out of the ifdef CONFIG_X86_ANDROID_TABLETS block.

Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.
Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.
Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)
In addition to that, there are the usual bunch of fixes and cleanups.
Specifics:
- Add CSI-2 and DisCo for Imaging support to the ACPI device
enumeration code (Sakari Ailus, Rafael J. Wysocki)
- Adjust the cpufreq thermal reduction algorithm in the ACPI
processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
Bergmann)
- Make acpi_proc_quirk_mwait_check() x86-specific (Rafael J. Wysocki)
- Switch over ACPI to using a threaded interrupt handler for the SCI
(Rafael J. Wysocki)
- Allow ACPI Notify () handlers to run on all CPUs and clean up the
ACPI interface for deferred events processing (Rafael J. Wysocki)
- Switch over the ACPI EC driver to using a threaded handler for the
dedicated IRQ on systems without the EC GPE (Rafael J. Wysocki)
- Adjust code using ACPICA spinlocks and the ACPI EC driver spinlock
to keep local interrupts on (Rafael J. Wysocki)
- Adjust the USB4 _OSC handshake to correctly handle cases in which
certain types of OS control are denied by the platform (Mika
Westerberg)
- Correct and clean up the generic function for parsing ACPI
data-only tables with array structure (Yuntao Wang)
- Modify acpi_dev_uid_match() to support different types of its
second argument and adjust its users accordingly (Raag Jadav)
- Clean up code related to acpi_evaluate_reference() and ACPI device
lists (Rafael J. Wysocki)
- Use generic ACPI helpers for evaluating trip point temperature
objects in the ACPI thermal zone driver (Rafael J. Wysockii, Arnd
Bergmann)
- Add Thermal fast Sampling Period (_TFP) support to the ACPI thermal
zone driver (Jeff Brasen)
- Modify the ACPI LPIT table handling code to avoid u32
multiplication overflows in state residency computations (Nikita
Kiryushin)
- Drop an unused helper function from the ACPI backlight (video)
driver and add a clarifying comment to it (Hans de Goede)
- Update the ACPI backlight driver to avoid using uninitialized
memory in some cases (Nikita Kiryushin)
- Add ACPI backlight quirk for the Colorful X15 AT 23 laptop (Yuluo
Qiu)
- Add support for vendor-defined error types to the ACPI APEI error
injection code (Avadhut Naik)
- Adjust APEI to properly set MF_ACTION_REQUIRED on synchronous
memory failure events, so they are handled differently from the
asynchronous ones (Shuai Xue)
- Fix NULL pointer dereference check in the ACPI extlog driver
(Prarit Bhargava)
- Adjust the ACPI extlog driver to clear the Extended Error Log
status when RAS_CEC handled the error (Tony Luck)
- Add IRQ override quirks for some Infinity laptops and for TongFang
GMxXGxx (David McFarland, Hans de Goede)
- Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is
not the same as one of the real pxm values (Yuntao Wang)
- Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC)
driver so as to prevent miscalculation of the values in the clock
divider (Andy Shevchenko)
- Adjust comments in the ACPI watchdog driver to prevent kernel-doc
from complaining during documentation builds (Randy Dunlap)
- Make the ACPI button driver send wakeup key events to user space in
addition to power button events on systems that can be woken up by
the power button (Ken Xue)
- Adjust pnpacpi_parse_allocated_vendor() to use memcpy() on a full
structure field (Dmitry Antipov)"

Move and rename cppc_cpufreq_perf_to_khz() and cppc_cpufreq_khz_to_perf() to
use them outside cppc_cpufreq in topology_init_cpu_capacity_cppc().
Modify the interface to use struct cppc_perf_caps *caps instead of
struct cppc_cpudata *cpu_data as we only use the fields of cppc_perf_caps.
cppc_cpufreq was converting the lowest and nominal freq from MHz to kHz
before using them. We move this conversion inside cppc_perf_to_khz and
cppc_khz_to_perf to make them generic and usable outside cppc_cpufreq.
