Now zconf_curname() and zconf_lineno() are so simple that they just
return cur_filename, cur_lineno, respectively.

Replace current_pos with separate variables representing the file name
and the line number, respectively.
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

yyerror() reports the line number of the next line.
This +1 adjustment was introduced more than 20 years ago [1]. At that

The line number management was refactored in a more maintainable way.
Such compensation is no longer needed.

When the Debian package build is initiated by Kbuild ('make deb-pkg'

Otherwise, let's show verbose messages (unless the 'terse' tag is set

should be as verbose as reasonably possible, except where the terse tag
is included in DEB_BUILD_OPTIONS." [1]

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.

Geert Uytterhoeven reported that commit 4e244c10eab3 ("kconfig: remove
unneeded symbol_empty variable") changed the default value of
CONFIG_LOG_CPU_MAX_BUF_SHIFT from 12 to 0.
As it turned out, this is an undefined behavior because sym_calc_value()
stopped setting the sym->curr.tri field for 'int', 'hex', and 'string'
symbols.
This commit restores the original behavior, where 'int', 'hex', 'string'
symbols are interpreted as false if used in boolean contexts.
CONFIG_LOG_CPU_MAX_BUF_SHIFT will default to 12 again, irrespective
of CONFIG_BASE_SMALL. Presumably, this is not the intended behavior,
as already reported [1], but this is another issue that should be
addressed by a separate patch.

The new installkernel application that is now included in systemd-udev
package allows installation although destination files are already present
in the boot directory of the kernel package, but is failing with the
implemented workaround for the old installkernel application from grubby
package.
For the new installkernel application, as Davide says:
<<The %post currently does a shuffling dance before calling installkernel.
This isn't actually necessary afaict, and the current implementation
ends up triggering downstream issues such as
https://github.com/systemd/systemd/issues/29568
This commit simplifies the logic to remove the shuffling. For reference,
the original logic was added in commit 3c9c7a14b627("rpm-pkg: add %post
section to create initramfs and grub hooks").>>
But we need to keep the old behavior as well, because the old installkernel
application from grubby package, does not allow this simplification and
we need to be backward compatible to avoid issues with the different
packages.
Mimic Fedora shipping process and store vmlinuz, config amd System.map
in the module directory instead of the boot directory. In this way, we will
avoid the commented problem for all the cases, because the new destination
files are not going to exist in the boot directory of the kernel package.
Replace installkernel tool with kernel-install tool, because the latter is
more complete.
Besides, after installkernel tool execution, check to complete if the
correct package files vmlinuz, System.map and config files are present
in /boot directory, and if necessary, copy manually for install operation.
In this way, take into account if files were not previously copied from
/usr/lib/kernel/install.d/* scripts and if the suitable files for the
requested package are present (it could be others if the rpm files were
replace with a new pacakge with the same release and a different build).
Tested with Fedora 38, Fedora 39, RHEL 9, Oracle Linux 9.3,
openSUSE Tumbleweed and openMandrive ROME, using dnf/zypper and rpm tools.

warning:
WARNING: modpost: vmlinux.o(__ex_table+0x88): Section mismatch in reference to the .ltext:(unknown)
WARNING: modpost: The relocation at __ex_table+0x88 references
section ".ltext" which is not in the list of

This can be achieved by adding ".ltext" to
OTHER_TEXT_SECTIONS in scripts/mod/modpost.c.
The linked LLVM change moves global objects to the '.ltext' (and
'.ltext.*' with '-ffunction-sections') sections with '-mcmodel=large',
which ARCH=um uses. These sections should be handled just as '.text'
and '.text.*' are, so add them to TEXT_SECTIONS.

Here is the big set of char/misc and other driver subsystem changes for
6.8-rc1. Lots of stuff in here, but first off, you will get a merge
conflict in drivers/android/binder_alloc.c when merging this tree due to
changing coming in through the -mm tree.
The resolution of the merge issue can be found here:
https://lore.kernel.org/r/20231207134213.25631ae9@canb.auug.org.au
or in a simpler patch form in that thread:
https://lore.kernel.org/r/ZXHzooF07LfQQYiE@google.com
If there are issues with the merge of this file, please let me know.
Other than lots of binder driver changes (as you can see by the merge
conflicts) included in here are:
- lots of iio driver updates and additions
- spmi driver updates
- eeprom driver updates
- firmware driver updates
- ocxl driver updates
- mhi driver updates
- w1 driver updates
- nvmem driver updates
- coresight driver updates
- platform driver remove callback api changes
- tags.sh script updates
- bus_type constant marking cleanups
- lots of other small driver updates
All of these have been in linux-next for a while with no reported issues
(other than the binder merge conflict.)

The existing mainline clang development version encounters difficulties
compiling the LoongArch kernel module. It is anticipated that this issue
will be resolved in the upcoming 18.0.0 release. To prevent user
confusion arising from broken builds, it is advisable to raise the
minimum required clang version for LoongArch to 18.0.0.

With recent trunk versions of binutils and gcc, alignment directives are
represented with R_LARCH_ALIGN relocs on LoongArch, which is necessary
for the linker to maintain alignment requirements during its relaxation
passes. And even though the kernel is built with relaxation disabled, so
far a small number of R_LARCH_RELAX marker relocs are still emitted as
part of la.* pseudo instructions in assembly. These two kinds of relocs
do not refer to symbols, which can trip up modpost's section mismatch
checks, because the r_offset of said relocs can be zero or any other
meaningless value, eventually leading to a `from == NULL` condition in
default_mismatch_handler and SIGSEGV.
As the two kinds of relocs are not concerned with symbols, just ignore
them for section mismatch check purposes.

GNU's addr2line can have problems parsing a vmlinux built with LLVM,
particularly when LTO was used. In order to decode the traces correctly
this patch adds the ability to switch to LLVM's utilities readelf and
addr2line. The same approach is followed by Will in [1].
Before:
$ scripts/decode_stacktrace.sh vmlinux < kernel.log
[17716.240635] Call trace:
[17716.240646] skb_cow_data (??:?)
[17716.240654] esp6_input (ld-temp.o:?)
[17716.240666] xfrm_input (ld-temp.o:?)
[17716.240674] xfrm6_rcv (??:?)
[...]
After:
$ LLVM=1 scripts/decode_stacktrace.sh vmlinux < kernel.log
[17716.240635] Call trace:
[17716.240646] skb_cow_data (include/linux/skbuff.h:2172 net/core/skbuff.c:4503)
[17716.240654] esp6_input (net/ipv6/esp6.c:977)
[17716.240666] xfrm_input (net/xfrm/xfrm_input.c:659)
[17716.240674] xfrm6_rcv (net/ipv6/xfrm6_input.c:172)
[...]
Note that one could set CROSS_COMPILE=llvm- instead to hack around this
issue. However, doing so can break the decodecode routine as it will
force the selection of other LLVM utilities down the line e.g. llvm-as.

__counted_by annotations.

structure members that disappeared a while back. That had the delightful
consequence of adding some 600 warnings to the docs build. A sustained

bringing the documentation back into sync with the code. The fixes are
going through the appropriate maintainer trees.

Another routine one in terms of features. In terms of lines, this time
the 'alloc' version upgrade is less prominent, given that it was fairly
small (and we did not have two upgrades).
Toolchain and infrastructure:
- Upgrade to Rust 1.74.1.
The patch release includes a fix for an ICE that the Apple AGX GPU
driver was hitting.
- Support 'srctree'-relative links in Rust code documentation.
- Automate part of the manual constants handling (i.e. the ones not
recognised by 'bindgen').
- Suppress searching builtin sysroot to avoid confusion with installed
sysroots, needed for the to-be-merged arm64 support which uses
a builtin target.
- Ignore '__preserve_most' functions for 'bindgen'.
- Reduce header inclusion bloat in exports.
'kernel' crate:
- Implement 'Debug' for 'CString'.
- Make 'CondVar::wait()' an uninterruptible wait.
'macros' crate:
- Update 'paste!' to accept string literals.
- Improve '#[vtable]' documentation.
Documentation:
- Add testing section (KUnit and 'rusttest' target).
- Remove 'CC=clang' mentions.
- Clarify that 'rustup override' applies to build directory.
