Masahiro Yamada 7d5f52a433 kconfig: do not imply the type of choice value
Do not feed back the choice type to choice values.

Each choice value should explicitly specify 'bool' or 'tristate',
as all the Kconfig files already do. If the type were missing,
"config symbol defined without type" would be shown.

Masahiro Yamada 980c9e198f kconfig: convert linked list of files to hash table
Currently, a linked list is used to keep track of all the Kconfig
files that have ever been parsed. Every time the "source" statement
is encountered, the linked list is traversed to check if the file has
been opened before. This prevents the same file from being recorded
in include/config/auto.conf.cmd again.

Given 1500+ Kconfig files parsed, a hashtable is now a more optimal
data structure.

By the way, you may wonder why we check this in the first place.
It matters only when the same file is included multiple times.
In old days, such a use case was forbidden, but commit f094f8a1b2
("kconfig: allow multiple inclusion of the same file") provided a bit
more flexibility. Of course, it is almost hypothetical...

Masahiro Yamada 4dae9cf5cb kconfig: split list_head into a separate header
The struct list_head is often embedded in other structures, while other
code is used in C functions.

By separating struct list_head into its own header, other headers are no
longer required to include the entire list.h.

This is similar to the kernel space, where struct list_head is defined
in <linux/types.h> instead of <linux/list.h>.

Masahiro Yamada 8facc5f319 kconfig: move the file and lineno in struct file to struct buffer
struct file has two link nodes, 'next' and 'parent'.

The former is used to link files in the 'file_list' linked list,
which manages the list of Kconfig files seen so far.

The latter is used to link files in the 'current_file' linked list,
which manages the inclusion ("source") tree.

The latter should be tracked together with the lexer state.

Replace current_pos with separate variables representing the file name

No functional change is intended.

By the way, you might wonder why the "<none>" fallback exists in
zconf_curname(). menu_add_symbol() saves the current file and the line
number. It is intended to be called only during the yyparse() time.
However, menu_finalize() calls it, where there is no file being parsed.
This is a long-standing hack that should be fixed later. I left a FIXME

the actual package removal.

Masahiro Yamada 24507871c3 kbuild: create a list of all built DTB files
It is useful to have a list of all *.dtb and *.dtbo files generated
from the current build.

With this commit, 'make dtbs' creates arch/*/boot/dts/dtbs-list, which
lists the dtb(o) files created in the current build. It maintains the
order of the dtb-y additions in Makefiles although the order is not
important for DTBs. It is a (good) side effect through the reuse of the
modules.order rule.

Please note this list only includes the files directly added to dtb-y.

For example, consider this case:

    foo-dtbs := foo_base.dtb foo_overlay.dtbo
    dtb-y := foo.dtb

In this example, the list will include foo.dtb, but not foo_base.dtb
or foo_overlay.dtbo.

The indentation was a mix of spaces and tabs; I've turned them all into

Also use ``...`` instead of `...`; the difference is that `` is meant

Linus Torvalds ced5905231 Driver core fixes for 6.8-rc5
Here are some driver core fixes, a kobject fix, and a documentation
 update for 6.8-rc5.  In detail these changes are:
   - devlink fixes for reported issues with 6.8-rc1
   - topology scheduling regression fix that has been reported by many
   - kobject loosening of checks change in -rc1 is now reverted as some
     codepaths seemed to need the checks
   - documentation update for the CVE process.  Has been reviewed by
     many, the last minute change to the document was to bring the .rst
     format back into the the new style rules, the contents did not
     change.
 
 All of these, except for the documentation update, have been in
 linux-next for over a week.  The documentation update has been reviewed
 for weeks by a group of developers, and in public for a week and the
 wording has stabilized for now.  If future changes are needed, we can do
 so before 6.8-final is out (or anytime after that.)
