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).
* iASL: Add support for the SVKL table (Bob Moore).

SVKL table headers (Kuppuswamy Sathyanarayanan).
* 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).

ACPI code (Hanjun Guo, Heiner Kallweit).
- Fix possible buffer overrun issue with the description_show()
sysfs attribute method (Krzysztof Wilczyński).

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).

use a common list of device IDs (Rafael Wysocki).

value if present in the firmware (James Morse).

Platform Runtime Mechanism Support (ACPI_PRMT) [Y/n/?] (NEW) ?
There is no help available for this option.
Symbol: ACPI_PRMT [=y]
Type : bool
Defined at drivers/acpi/Kconfig:547
Prompt: Platform Runtime Mechanism Support
Depends on: EFI [=y] && X86_64 [=y]
Location:
-> Power management and ACPI options
Platform Runtime Mechanism Support (ACPI_PRMT) [Y/n/?] (NEW)
I don't know what that means, there's no help, no nothing. And it is
default y for no apparent reason.
/me looks at the commit message:
Platform Runtime Mechanism (PRM) is a firmware interface that exposes
a set of binary executables that can either be called from the AML
interpreter or device drivers by bypassing the AML interpreter.
This change implements the AML interpreter path.
I'm still unclear whether I need it or not.
Guys, you need to think about your users and to write help text which is
*actually* usable for people who do not deal with ACPI firmware gunk.
Thx.

That's a fair point.

We will.
What about the following help text (white space damage by gmail)?
