Merge branches 'acpi-scan', 'acpi-bus', 'acpi-tables' and 'acpi-sysfs'

Merge ACPI changes related to device enumeration, device object
managenet, operation region handling, table parsing and sysfs
interface:

- Use ZERO_PAGE(0) instead of empty_zero_page in the ACPI device
enumeration code (Giulio Benetti).

- Change the return type of the ACPI driver remove callback to void and
update its users accordingly (Dawei Li).

- Add general support for FFH address space type and implement the low-
level part of it for ARM64 (Sudeep Holla).

- Fix stale comments in the ACPI tables parsing code and make it print
more messages related to MADT (Hanjun Guo, Huacai Chen).

- Replace invocations of generic library functions with more kernel-
specific counterparts in the ACPI sysfs interface (Christophe JAILLET,
Xu Panda).

* acpi-scan:
ACPI: scan: substitute empty_zero_page with helper ZERO_PAGE(0)

* acpi-bus:
ACPI: FFH: Silence missing prototype warnings
ACPI: make remove callback of ACPI driver void
ACPI: bus: Fix the _OSC capability check for FFH OpRegion
arm64: Add architecture specific ACPI FFH Opregion callbacks
ACPI: Implement a generic FFH Opregion handler

* acpi-tables:
ACPI: tables: Fix the stale comments for acpi_locate_initial_tables()
ACPI: tables: Print CORE_PIC information when MADT is parsed

* acpi-sysfs:
ACPI: sysfs: use sysfs_emit() to instead of scnprintf()
ACPI: sysfs: Use kstrtobool() instead of strtobool()

ACPI: Implement a generic FFH Opregion handler

ACPI: Implement a generic FFH Opregion handler

This registers the FFH OpRegion handler before ACPI tables are
loaded. The platform support for the same is checked via Platform-Wide
OSPM Capabilities(OSC) before registering the OpRegion handler.

It relies on the special context data passed to offset and the length.
However the interpretation of the values is platform/architecture
specific. This generic handler just passed all the information to
the platform/architecture specific callback. It also implements the
default callbacks which return as not supported.

Merge tag 'acpi-5.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
"These rework the handling of ACPI device objects to use the driver
core facilities for managing child ones instead of some questionable
home-grown ways without the requisite locking and reference counting,
clean up the EC driver, improve suspend-to-idle handling on x86, add
some systems to the ACPI backlight quirk list, fix some assorted
issues, clean up code and improve documentation.

Specifics:

- Use facilities provided by the driver core and some additional
helpers to handle the children of a given ACPI device object in
multiple places instead of using the children and node list heads
in struct acpi_device which is error prone (Rafael Wysocki).

- Fix ACPI-related device reference counting issue in the hisi_lpc
bus driver (Yang Yingliang).

- Drop the children and node list heads that are not needed any more
from struct acpi_device (Rafael Wysocki).

- Drop driver member from struct acpi_device (Uwe Kleine-König).

- Drop redundant check from acpi_device_remove() (Uwe Kleine-König).

- Prepare the CPPC library for handling backwards-compatible future
_CPC return package formats gracefully (Rafael Wysocki).

- Clean up the ACPI EC driver after previous changes in it (Hans de
Goede).

- Drop leftover acpi_processor_get_limit_info() declaration (Riwen
Lu).

- Split out thermal initialization from ACPI PSS (Riwen Lu).

- Annotate more functions in the ACPI CPU idle driver to live in the
cpuidle section (Guilherme G. Piccoli).

- Fix _EINJ vs "special purpose" EFI memory regions (Dan Williams).

- Implement a better fix to avoid spamming the console with old error
logs (Tony Luck).

- Fix typo in a comment in the APEI code (Xiang wangx).

- Save NVS memory during transitions into S3 on Lenovo G40-45 (Manyi
Li).

- Add support for upcoming AMD uPEP device ID AMDI008 to the ACPI
suspend-to-idle driver for x86 platforms (Shyam Sundar S K).

- Clean up checks related to the ACPI_FADT_LOW_POWER_S0 platform flag
in the LPIT table driver and the suspend-to-idle driver for x86
platforms (Rafael Wysocki).

- Print information messages regarding declared LPS0 idle support in
the platform firmware (Rafael Wysocki).

- Fix missing check in register_device_clock() in the ACPI driver for
Intel SoCs (huhai).

- Fix ACS setup in the VIOT table parser (Eric Auger).

- Skip IRQ override on AMD Zen platforms where it's harmful
(Chuanhong Guo).

- Use native backlight on Dell Inspiron N4010 (Hans de Goede).

- Use native backlight on some TongFang devices (Werner Sembach).

- Drop X86 dependency from the ACPI backlight driver Kconfig (Riwen
Lu).

- Shorten the quirk list in the ACPI backlight driver by identifying
Clevo by board_name only (Werner Sembach).

- Remove useless NULL pointer checks from 2 ACPI PCI link management
functions (Andrey Strachuk).

- Fix obsolete example in the ACPI EINJ documentation (Qifu Zhang).

- Update links and references to _DSD-related documents (Sudeep
Holla)"

ACPI: processor: Split out thermal initialization from ACPI PSS

ACPI: processor: Split out thermal initialization from ACPI PSS

Commit 239708a3af44 ("ACPI: Split out ACPI PSS from ACPI Processor
driver"), moves processor thermal registration to acpi_pss_perf_init(),
which doesn't get executed if ACPI_CPU_FREQ_PSS is not enabled.

As ARM64 supports P-states using CPPC, it should be possible to also
support processor passive cooling even if PSS is not enabled. Split
out the processor thermal cooling register from ACPI PSS to support
this, and move it into a separate function in processor_thermal.c.
