Pull scipts/sorttable updates from Steven Rostedt:
"The sorttable.c was a copy from recordmcount.c which is very hard to
maintain. That's because it uses macro helpers and places the code in
a header file sorttable.h to handle both the 64 bit and 32 bit version
of the Elf structures. It also uses _r()/r()/r2() wrappers around
accessing the data which will read the 64 bit or 32 bit version of the
data as well as handle endianess. If the wrong wrapper is used, an
invalid value will result, and this has been a cause for bugs in the
past. In fact the new ORC code doesn't even use it. That's fine
because ORC is only for 64 bit x86 which is the default parsing.
Instead of having a bunch of macros defined and then include the code
twice from a header, the Elf structures are each wrapped in a union.
The union holds the 64 bit and 32 bit version of the needed structure.
Then a structure of function pointers is used, along with helper
macros to access the ELF types appropriately for their byte size and
endianess. How to reference the data fields is moved from the code
that implements the sorting to the helper functions where all accesses
to a field will use he same helper function. As long as the helper
functions access the fields correctly, the code will also access the
fields. This is an improvement over having to code implementing the
sorting having to make sure it always uses the right accessor function
when reading an ELF field.
This is a clean up only, the functionality of the scripts/sorttable.c
does not change"

Since commit bdf8eafbf7 ("arm64: stacktrace: report source of unwind
data") a stack trace line can contain an additional info field that was not
present before, in the form of one or more letters in parentheses. E.g.:
[ 504.517915] led_sysfs_enable+0x54/0x80 (P)
^^^
When this is present, decode_stacktrace decodes the line incorrectly:
[ 504.517915] led_sysfs_enable+0x54/0x80 P
Extend parsing to decode it correctly:
[ 504.517915] led_sysfs_enable (drivers/leds/led-core.c:455 (discriminator 7)) (P)
The regex to match such lines assumes the info can be extended in the
future to other uppercase characters, and will need to be extended in case
other characters will be used. Using a much more generic regex might incur
in false positives, so this looked like a good tradeoff.

With the latest binutils, modpost fails with a bus error on some
architectures such as ARM and sparc64.
Since binutils commit 1f1b5e506bf0 ("bfd/ELF: restrict file alignment
for object files"), the byte offset to each section (sh_offset) in
relocatable ELF is no longer guaranteed to be aligned.
modpost parses MODULE_DEVICE_TABLE() data structures, which are usually
located in the .rodata section. If it is not properly aligned, unaligned
access errors may occur.
To address the issue, this commit imports the get_unaligned() helper
from include/linux/unaligned.h.
The get_unaligned_native() helper caters to the endianness in addition
to handling the unaligned access.
I slightly refactored do_pcmcia_entry() and do_input() to avoid writing
back to an unaligned address. (We would need the put_unaligned() helper
to do that.)
The addend_*_rel() functions need similar adjustments because the .text
sections are not aligned either.
It seems that the .symtab, .rel.* and .rela.* sections are still aligned.
Keep normal pointer access for these sections to avoid unnecessary
performance costs.

Since commit cdd30ebb1b ("module: Convert symbol namespace to string

ignored by "kernel-doc -export" in fresh build of "make htmldocs".
This is because regex in the perl script for those markers fails to

- EXPORT_SYMBOL_NS(symbol, "ns");
- EXPORT_SYMBOL_NS_GPL(symbol, "ns");
Update the regex so that it matches quoted string.
Note: Escape sequence of \w is good for C identifiers, but can be
too strict for quoted strings. Instead, use \S, which matches any
non-whitespace character, for compatibility with possible extension
of namespace convention in the future [1].

Since commit 0043ecea23 ("vmlinux.lds.h: Adjust symbol ordering in
text output section"), the exception table in arch/openrisc/kernel/head.S
is no longer positioned at the very beginning of the kernel image, which
causes a boot failure.
Currently, the exception table resides in the regular .text section.
Previously, it was placed at the head by relying on the linker receiving
arch/openrisc/kernel/head.o as the first object. However, this behavior
has changed because sections like .text.{asan,unknown,unlikely,hot} now
precede the regular .text section.
The .head.text section is intended for entry points requiring special
placement. However, in OpenRISC, this section has been misused: instead
of the entry points, it contains boot code meant to be discarded after
booting. This feature is typically handled by the .init.text section.
This commit addresses the issue by replacing the current __HEAD marker
with __INIT and re-annotating the entry points with __HEAD. Additionally,
it adds __REF to entry.S to suppress the following modpost warning:
WARNING: modpost: vmlinux: section mismatch in reference: _tng_kernel_start+0x70 (section: .text) -> _start (section: .init.text)

MODULE_DEVICE_TABLE(of, foo_ids);
Currently, modpost outputs a meaningless suggestion:
ERROR: modpost: ...: sizeof(struct of_device_id)=200 is not a modulo of the size of section __mod_device_table__of__<identifier>=64.
Fix definition of struct of_device_id in mod_devicetable.h
The root cause here is that MODULE_DEVICE_TABLE(of, ...) is used instead
of the correct MODULE_DEVICE_TABLE(acpi, ...).
This commit provides a more intuitive error message:
ERROR: modpost: ...: type mismatch between foo_ids[] and MODULE_DEVICE_TABLE(of, ...)
The second error message, related to a missing terminator, is too
verbose.
[Example 2]
static const struct acpi_device_id foo_ids[] = {
{ "FOO" },
};
MODULE_DEVICE_TABLE(acpi, foo_ids);
The current error message is overly long, and does not pinpoint the
incorrect array:
...: struct acpi_device_id is 32 bytes. The last of 1 is:
0x46 0x4f 0x4f 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00
ERROR: modpost: ...: struct acpi_device_id is not terminated with a NULL entry!
This commit changes it to a more concise error message, sufficient to
identify the incorrect array:
ERROR: modpost: ...: foo_ids[] is not terminated with a NULL entry
Lastly, this commit squashes device_id_check() into do_table() and
changes fatal() into error(), allowing modpost to continue processing
other modules.

This commit renames the alias symbol, __mod_<type>__<name>_device_table
to __mod_device_table__<type>__<name>.
This change simplifies the code slightly, as there is no longer a need
to check both the prefix and suffix.

This commit renames the variables in handle_moddevtable() as follows:
name -> type
namelen -> typelen
identifier -> name
These changes align with the definition in include/linux/module.h:
extern typeof(name) __mod_##type##__##name##_device_table
