1ceebe2e46 x86/acpi: Add support for CPU offlining for ACPI MADT wakeup method
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.

6630cbce7c x86/acpi: Rename fields in the acpi_madt_multiproc_wakeup structure
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.

   computations from container_of() in some cases (Andy Shevchenko).

 - Do some assorted cleanups of the ACPI device enumeration code (Andy
   Shevchenko).

 - Make the ACPI device enumeration code skip devices with _STA values
   clearly identified by the specification as invalid (Rafael Wysocki).

 - Rework the handling of the NHLT table to simplify and clarify it and
   drop some obsolete pieces (Cezary Rojewski).

ACPICA commit c581606cf49b7574d29c02b1a3bc144650375e32

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.

2f7d7ea44a ACPI: NHLT: Reintroduce types the table consists of
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.

f3b19adef6 ACPICA: MADT: Add RISC-V external interrupt controllers
ACPICA commit 8c048cee4ea7b9ded8db3e1b3b9c14e21e084a2c

This adds 3 different external interrupt controller
definitions in MADT for RISC-V.

 1) RISC-V PLIC is a platform interrupt controller for
    handling wired interrupt in a RISC-V systems.

 2) RISC-V IMSIC is MSI interrupt controller to
    support MSI interrupts.

 3) RISC-V APLIC has dual functionality. First it can
    act like PLIC and direct all wired interrupts to
    the CPU which doesn't have MSI controller. Second,
    when the CPU has MSI controller (IMSIC), it will
    act as a converter from wired interrupts to MSI.

Update the existing RINTC structure also to support
these external interrupt controllers.

This codefirst ECR is approved by UEFI forum and will
be part of next ACPI spec version.

2a5ab99847 ACPICA: struct acpi_nfit_interleave: Replace 1-element array with flexible array
ACPICA commit e66decc6fca36b59194b0947d87d6a9bec078bc3

Similar to "Replace one-element array with flexible-array", replace the
1-element array with a proper flexible array member as defined by C99.

This allows the code to operate without tripping compile-time and run-
time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds,
and/or -fstrict-flex-arrays=3).

Unlike struct acpi_nfit_flush_address and struct acpi_nfit_smbios, which
had their sizeof() uses adjusted in code, struct acpi_nfit_interleave did
not. This appears to have been a bug. After this change, there is a binary
difference in acpi_dm_dump_nfit() since the size of the structure now has
the correct size, as the prior result was including the trailing U32:

-       mov    $0x14,%ebp
+       mov    $0x10,%ebp

86f240a2f7 ACPICA: Headers: Delete bogus node_array array of pointers from AEST table
ACPICA commit f0c4a06f1dfc4886d4e0c2aa30bc57b10c5a8c53

Like many tables, this is a header followed by multiple subtables of
varying self-identifying types, and ACPICA does not normally add a field
for the subtables, instead relying on pointer arithmetic past the end of
the first header struct, since indexing a flexible array member is
meaningless for variable-length entries. If we really wanted a field for
this, we could use a u8 flexible array member, but it contradicts the
current style. Using void *, however, is categorically wrong, as ACPI
tables never contain native C-language pointers.

aa29b2083e ACPICA: Headers: Replace zero-length array with flexible-array member
ACPICA commit 98835f452c698b015d4da999944405ecb90da670

There is a regular need in the kernel to provide a way to declare
having a dynamically sized set of trailing elements in a structure.
Kernel code should always use “flexible array members”[1] for these
cases. The older style of one-element or zero-length arrays should
no longer be used[2].

00395b74d5 ACPICA: Fix AEST Processor generic resource substructure data field byte length
ACPICA commit 13b9327761955f6e1e5dbf748b3112940c0dc539

The byte length of the Data field in the AEST Processor generic resource
substructure defined in ACPI for the Armv8 RAS Extensions 1.1 is 4Byte.
However, it is defined as a pointer type, and on a 64-bit machine,
it is interpreted as 8 bytes. Therefore, it is changed from a pointer
type unsigned integer 1 byte to an unsigned integer 4 bytes.

b2ffa16a1c Merge branches 'acpi-x86', 'acpi-resources', 'acpi-scan' and 'acpi-misc'
Merge x86-specific ACPI updates, ACPI resources management updates,
one ACPI device enumeration update and miscellaneous ACPI updates for
5.16-rc1:

 - 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).

* acpi-x86:
  x86: ACPI: cstate: Optimize C3 entry on AMD CPUs
  x86/ACPI: Don't add CPUs that are not online capable
  ACPICA: Add support for MADT online enabled bit

* acpi-resources:
  ACPI: resources: Add one more Medion model in IRQ override quirk
  ACPI: resources: Add DMI-based legacy IRQ override quirk

* acpi-scan:
  ACPI: scan: Release PM resources blocked by unused objects

* acpi-misc:
  ACPI: replace snprintf() in "show" functions with sysfs_emit()
  ACPI: Update information in MAINTAINERS
