Subject[GIT PULL] ACPI updates for v5.14-rc1
Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
acpi-5.14-rc1

with top-most commit 64f9111dd6225a50b8fdd365dfdda275c2a708c0

Merge branches 'acpi-ec', 'acpi-apei', 'acpi-soc' and 'acpi-misc'

on top of commit 009c9aa5be652675a06d5211e1640e02bbb1c33d

Linux 5.13-rc6

to receive ACPI updates for 5.14-rc1.

These update the ACPICA code in the kernel to the 20210604
upstream revision, add preliminary support for the Platform
Runtime Mechanism (PRM), address issues related to the handling
of device dependencies in the ACPI device eunmeration code,
improve the tracking of ACPI power resource states, improve
the ACPI support for suspend-to-idle on AMD systems, continue
the unification of message printing in the ACPI code, address
assorted issues and clean up the code in a number of places.

Specifics:

- Update ACPICA code in the kernel to upstrea revision 20210604
including the following changes:

* Add defines for the CXL Host Bridge Structureand and add the
CFMWS structure definition to CEDT (Alison Schofield).
* iASL: Finish support for the IVRS ACPI table (Bob Moore).

* Use ACPI_FALLTHROUGH (Wei Ming Chen).

- Add preliminary support for the Platform Runtime Mechanism (PRM)
to allow the AML interpreter to call PRM functions (Erik Kaneda).

- Address some issues related to the handling of device dependencies
reported by _DEP in the ACPI device enumeration code and clean up
some related pieces of it (Rafael Wysocki).

- Improve the tracking of states of ACPI power resources (Rafael
Wysocki).

- Improve ACPI support for suspend-to-idle on AMD systems (Alex
Deucher, Mario Limonciello, Pratik Vishwakarma).

- Continue the unification and cleanup of message printing in the
ACPI code (Hanjun Guo, Heiner Kallweit).

- Fix possible buffer overrun issue with the description_show()
sysfs attribute method (Krzysztof Wilczyński).

- Improve the acpi_mask_gpe kernel command line parameter handling
and clean up the core ACPI code related to sysfs (Andy Shevchenko,
Baokun Li, Clayton Casciato).

- Postpone bringing devices in the general ACPI PM domain to D0
during resume from system-wide suspend until they are really
needed (Dmitry Torokhov).

- Make the ACPI processor driver fix up C-state latency if not
ordered (Mario Limonciello).

- Add support for identifying devices depending on the given one
that are not its direct descendants with the help of _DEP (Daniel
Scally).

- Extend the checks related to ACPI IRQ overrides on x86 in order to
avoid false-positives (Hui Wang).

- Add battery DPTF participant for Intel SoCs (Sumeet Pawnikar).

- Rearrange the ACPI fan driver and device power management code to
use a common list of device IDs (Rafael Wysocki).

- Fix clang CFI violation in the ACPI BGRT table parsing code and
clean it up (Nathan Chancellor).

- Add GPE-related quirks for some laptops to the EC driver (Chris
Chiu, Zhang Rui).

- Make the ACPI PPTT table parsing code populate the cache-id
value if present in the firmware (James Morse).

- Remove redundant clearing of context->ret.pointer from
acpi_run_osc() (Hans de Goede).

- Add missing acpi_put_table() in acpi_init_fpdt() (Jing Xiangfeng).

- Make ACPI APEI handle ARM Processor Error CPER records like
Memory Error ones to avoid user space task lockups (Xiaofei Tan).

- Stop warning about disabled ACPI in APEI (Jon Hunter).

- Fix fall-through warning for Clang in the SBSHC driver (Gustavo A.
R. Silva).

- Add custom DSDT file as Makefile prerequisite (Richard Fitzgerald).

- Initialize local variable to avoid garbage being returned (Colin
Ian King).

- Simplify assorted pieces of code, address assorted coding style
and documentation issues and comment typos (Baokun Li, Christophe
JAILLET, Clayton Casciato, Liu Shixin, Shaokun Zhang, Wei Yongjun,
Yang Li, Zhen Lei).

Thanks!
