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

ACPICA commit 44f1af0664599e87bebc3a1260692baa27b2f264

The sizeof() uses with struct acpi_nfit_flush_address and struct
acpi_nfit_smbios have been adjusted to drop the open-coded subtraction
of the trailing single element. The result is no binary differences in
.text nor .data sections.

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.

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.

Note: support for Vendor-defined microphone arrays and SNR extensions
are not supported at this time -- mostly due to a lack of example tables.
Actual compiler support for NHLT is forthcoming.
