"These are usual ACPICA code updates (although there are more of them
than in the last few releases), a noticeable EC driver update (which
mostly consists of cleanups, though), the device enumeration quirks
handling rework from Hans, some updates eliminating unnecessary CPU
cache flushing in some places (processor idle and system-wide PM code)
and a bunch of assorted cleanups and fixes.

ACPI: PM: Remove redundant cache flushing

ACPICA code takes care about cache flushing on S1/S2/S3 in
acpi_hw_extended_sleep() and acpi_hw_legacy_sleep().

acpi_suspend_enter() calls into ACPICA code via acpi_enter_sleep_state()
for S1 or x86_acpi_suspend_lowlevel() for S3.

acpi_sleep_prepare() call tree:
__acpi_pm_prepare()
acpi_pm_prepare()
acpi_suspend_ops::prepare_late()
acpi_hibernation_ops::pre_snapshot()
acpi_hibernation_ops::prepare()
acpi_suspend_begin_old()

acpi_hibernation_ops_old::acpi_hibernation_begin_old()
acpi_power_off_prepare()

Hibernation (S4) and Power Off (S5) don't require cache flushing, so
the only interesting callsites are acpi_suspend_ops::prepare_late()
and acpi_suspend_begin_old::begin(). Both of them have cache flush
on ->enter() operation in acpi_suspend_enter().

Remove redundant ACPI_FLUSH_CPU_CACHE() in acpi_sleep_prepare() and
acpi_suspend_enter().

PM: hibernate: Allow ACPI hardware signature to be honoured

Theoretically, when the hardware signature in FACS changes, the OS
is supposed to gracefully decline to attempt to resume from S4:

"If the signature has changed, OSPM will not restore the system
context and can boot from scratch"

In practice, Windows doesn't do this and many laptop vendors do allow
the signature to change especially when docking/undocking, so it would
be a bad idea to simply comply with the specification by default in the
general case.

However, there are use cases where we do want the compliant behaviour
and we know it's safe. Specifically, when resuming virtual machines where
we know the hypervisor has changed sufficiently that resume will fail.
We really want to be able to *tell* the guest kernel not to try, so it
boots cleanly and doesn't just crash. This patch provides a way to opt
in to the spec-compliant behaviour on the command line.

A follow-up patch may do this automatically for certain "known good"
machines based on a DMI match, or perhaps just for all hypervisor
guests since there's no good reason a hypervisor would change the
hardware_signature that it exposes to guests *unless* it wants them
to obey the ACPI specification.

Merge tag 'acpi-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
"These update the ACPICA code in the kernel to the most recent upstream
revision, address some issues related to the ACPI power resources
management, simplify the enumeration of PCI devices having ACPI
companions, add new quirks, fix assorted problems, update the
ACPI-related information in maintainers and clean up code in several
places.

Specifics:

- Update the ACPICA code in the kernel to upstream revision 20210930
including the following changes:

- Fix system-wide resume issue caused by evaluating control
methods too early in the resume path (Rafael Wysocki).

- Add support for Windows 2020 _OSI string (Mario Limonciello).

- Add Generic Port Affinity type for SRAT (Alison Schofield).

- Add disassembly support for the NHLT ACPI table (Bob Moore).

- Avoid flushing caches before entering C3 type of idle states on AMD
processors (Deepak Sharma).

- Avoid enumerating CPUs that are not present and not online-capable
according to the platform firmware (Mario Limonciello).

- Add DMI-based mechanism to quirk IRQ overrides and use it for two
platforms (Hui Wang).

- Change the configuration of unused ACPI device objects to reflect
the D3cold power state after enumerating devices (Rafael Wysocki).

- Update MAINTAINERS information regarding ACPI (Rafael Wysocki).

- Fix typo in ACPI Kconfig (Masanari Iid).

- Use sysfs_emit() instead of snprintf() in some places (Qing Wang).

- Make the association of ACPI device objects with PCI devices more
straightforward and simplify the code doing that for all devices in
general (Rafael Wysocki).

- Use acpi_device_adr() in acpi_find_child_device() instead of
evaluating _ADR (Rafael Wysocki).

- Drop duplicate device IDs from PNP device IDs list (Krzysztof
Kozlowski).

- Allow acpi_idle_play_dead() to use C3 on AMD processors (Richard
Gong).

- Use ACPI_COMPANION() to simplify code in some drivers (Rafael
Wysocki).

- Check the states of all ACPI power resources during initialization
to avoid dealing with power resources in unknown states (Rafael
Wysocki).

- Fix ACPI power resource issues related to sharing wakeup power
resources (Rafael Wysocki).

- Avoid registering redundant suspend_ops (Rafael Wysocki).

- Report battery charging state as "full" if it appears to be over
the design capacity (André Almeida).

- Quirk GK45 mini PC to skip reading _PSR in the AC driver (Stefan
Schaeckeler).

- Mark apei_hest_parse() static (Christoph Hellwig).

- Relax platform response timeout to 1 second after instructing it to
inject an error (Shuai Xue).

- Make the PRM code handle memory allocation and remapping failures
more gracefully and drop some unnecessary blank lines from that
code (Aubrey Li).

- Fix spelling mistake in the ACPI documentation (Colin Ian King)"
