decode_stacktrace.sh adds a trailing space at the end of the decoded stack
if the module is not set (in most of the lines), which makes the some
lines of the stack having trailing space and some others not.
Do not add an extra space at the end of the line if module is not set,
adding consistency in output formatting.

When the ESC key is pressed, the parentSelected() signal is currently
emitted for singleMode, menuMode, and symbolMode.
However, parentSelected() signal is functional only for singleMode.
In menuMode, the signal is connected to the goBack() slot, but nothing
occurs because configList->rootEntry is always &rootmenu.
In symbolMode (in the right pane), the parentSelected() signal is not
connected to any slot.
This commit prevents the unnecessary emission of the parentSelected()
signal.

This script has been broken for 5 years with no user complaints.
It first had its .mod.c parser broken in commit a3d0cb04f7df ("modpost:
use __section in the output to *.mod.c"). Later, it had its object file
enumeration broken in commit f65a486821cf ("kbuild: change module.order

no reports.
Rather than reviving this script as we make further changes to `.mod.c`,
this patch gets rid of it because it is clearly unused.

To allow the Rust implementation of static_key_false to use runtime code
patching instead of the generic implementation, pull in the relevant
inline assembly from the jump_label.h header by running the C
preprocessor on a .rs.S file. Build rules are added for .rs.S files.
Since the relevant inline asm has been adjusted to export the inline asm
via the ARCH_STATIC_BRANCH_ASM macro in a consistent way, the Rust side
does not need architecture specific code to pull in the asm.
It is not possible to use the existing C implementation of
arch_static_branch via a Rust helper because it passes the argument
`key` to inline assembly as an 'i' parameter. Any attempt to add a C
helper for this function will fail to compile because the value of `key`
must be known at compile-time.

Some architectures embed boot DTBs in vmlinux. A potential issue for
these architectures is a race condition during parallel builds because
Kbuild descends into arch/*/boot/dts/ twice.
One build thread is initiated by the 'dtbs' target, which is a
prerequisite of the 'all' target in the top-level Makefile:
ifdef CONFIG_OF_EARLY_FLATTREE
all: dtbs
endif
For architectures that support the built-in boot dtb, arch/*/boot/dts/
is visited also during the ordinary directory traversal in order to
build obj-y objects that wrap DTBs.
Since these build threads are unaware of each other, they can run
simultaneously during parallel builds.
This commit introduces a generic build rule to scripts/Makefile.vmlinux
to support embedded boot DTBs in a race-free way. Architectures that
want to use this rule need to select CONFIG_GENERIC_BUILTIN_DTB.
After the migration, Makefiles under arch/*/boot/dts/ will be visited
only once to build only *.dtb files.
This change also aims to unify the CONFIG options used for built-in DTBs
support. Currently, different architectures use different CONFIG options
for the same purposes.
With this commit, the CONFIG options will be unified as follows:
- CONFIG_GENERIC_BUILTIN_DTB
This enables the generic rule for built-in boot DTBs. This will be
renamed to CONFIG_BUILTIN_DTB after all architectures migrate to the
generic rule.
- CONFIG_BUILTIN_DTB_NAME
This specifies the path to the embedded DTB.
(relative to arch/*/boot/dts/)
- CONFIG_BUILTIN_DTB_ALL
If this is enabled, all DTB files compiled under arch/*/boot/dts/ are
embedded into vmlinux. Only used by MIPS.

When building a 64-bit kernel on a 32-bit build host, incorrect
input MODULE_ALIAS() entries may be generated.
For example, when compiling a 64-bit kernel with CONFIG_INPUT_MOUSEDEV=m
on a 64-bit build machine, you will get the correct output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*r*a*0,*1,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*r*a*0,*1,*18,*1C,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*r*a*0,*1,*m*l*s*f*w*");
However, building the same kernel on a 32-bit machine results in
incorrect output:
$ grep MODULE_ALIAS drivers/input/mousedev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*110,*130,*r*0,*1,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*2,*k*r*8,*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*14A,*16A,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*145,*165,*r*a*0,*1,*18,*1C,*20,*21,*38,*3C,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*3,*k*110,*130,*r*a*0,*1,*20,*21,*m*l*s*f*w*");
A similar issue occurs with CONFIG_INPUT_JOYDEV=m. On a 64-bit build
machine, the output is:
$ grep MODULE_ALIAS drivers/input/joydev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*2,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*8,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*6,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*120,*r*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*130,*r*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*r*a*m*l*s*f*w*");
However, on a 32-bit machine, the output is incorrect:
$ grep MODULE_ALIAS drivers/input/joydev.mod.c
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*0,*20,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*2,*22,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*8,*28,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*3,*k*r*a*6,*26,*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*11F,*13F,*r*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*11F,*13F,*r*a*m*l*s*f*w*");
MODULE_ALIAS("input:b*v*p*e*-e*1,*k*2C0,*2E0,*r*a*m*l*s*f*w*");
When building a 64-bit kernel, BITS_PER_LONG is defined as 64. However,
on a 32-bit build machine, the constant 1L is a signed 32-bit value.
Left-shifting it beyond 32 bits causes wraparound, and shifting by 31
or 63 bits makes it a negative value.
The fix in commit e0e92632715f ("[PATCH] PATCH: 1 line 2.6.18 bugfix:
modpost-64bit-fix.patch") is incorrect; it only addresses cases where
a 64-bit kernel is built on a 64-bit build machine, overlooking cases
on a 32-bit build machine.
Using 1ULL ensures a 64-bit width on both 32-bit and 64-bit machines,
avoiding the wraparound issue.

When CONFIG_SATA_AHCI_PLATFORM=m, modpost outputs incorect acpi
MODULE_ALIAS() if the endianness of the target and the build machine
do not match.
When the endianness of the target kernel and the build machine match,
the output is correct:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:010601:*");
However, when building a little-endian kernel on a big-endian machine
(or vice versa), the output is incorrect:
$ grep 'MODULE_ALIAS("acpi' drivers/ata/ahci_platform.mod.c
MODULE_ALIAS("acpi*:APMC0D33:*");
MODULE_ALIAS("acpi*:0601??:*");
The 'cls' and 'cls_msk' fields are 32-bit.
DEF_FIELD() must be used instead of DEF_FIELD_ADDR() to correctly handle
endianness of these 32-bit fields.
The check 'if (cls)' was unnecessary; it never became NULL, as it was
the pointer to 'symval' plus the offset to the 'cls' field.

Since commit f79dc03fe68c ("kconfig: refactor choice value
calculation"), when EXPERT is disabled, nothing within the "if INPUT"
... "endif" block in drivers/input/Kconfig is displayed. This issue
affects all command-line interfaces and GUI frontends.
The prompt for INPUT is hidden when EXPERT is disabled. Previously,
menu_is_visible() returned true in this case; however, it now returns
false, resulting in all sub-menu entries being skipped.
Here is a simplified test case illustrating the issue:
config A
bool "A" if X
default y
config B
bool "B"
depends on A
When X is disabled, A becomes unconfigurable and is forced to y.
B should be displayed, as its dependency is met.
This commit restores the necessary code, so menu_is_visible() functions
as it did previously.

The Debian kernel supports the pkg.linux.nokerneldbg build profile.
The debug package tends to become huge, and you may not want to build
it even when CONFIG_DEBUG_INFO is enabled.
This commit introduces a similar profile for the upstream kernel.

Since commit f1d87664b82a ("kbuild: cross-compile linux-headers package
when possible"), 'make bindeb-pkg' may attempt to cross-compile the
linux-headers package, but it fails under certain circumstances.
For example, when CONFIG_MODULE_SIG_FORMAT is enabled on Debian, the
following command fails:
$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg

This commit adds a new profile, pkg.linux-upstream.nokernelheaders, to
guard the linux-headers package.
There are two options to fix the above issue.
Option 1: Set the pkg.linux-upstream.nokernelheaders build profile
$ DEB_BUILD_PROFILES=pkg.linux-upstream.nokernelheaders \
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- bindeb-pkg
This skips the building of the linux-headers package.
Option 2: Install the necessary build dependencies
If you want to cross-compile the linux-headers package, you need to
install additional packages.
For example, on Debian, the packages necessary for cross-compiling it
to arm64 can be installed with the following commands:
# dpkg --add-architecture arm64
# apt update
# apt install gcc-aarch64-linux-gnu libssl-dev:arm64

I believe this issue is less common on Fedora because the disto's cross-
compilier cannot link user-space programs. Hence, CONFIG_CC_CAN_LINK is
unset.
On Fedora 40, the package information explains this limitation clearly:
$ dnf info gcc-aarch64-linux-gnu
[ snip ]
Description : Cross-build GNU C compiler.
:
: Only building kernels is currently supported. Support for cross-building
: user space programs is not currently provided as that would massively multiply
: the number of packages.
Anyway, cross-compiling RPM packages is somewhat challenging.
This commit disables the kernel-devel package when cross-compiling
because I did not come up with a better solution.

On powerpc, we would like to be able to make a pass on vmlinux.o and
generate a new object file to be linked into vmlinux. Add a generic pass
in Makefile.vmlinux that architectures can use for this purpose.
Architectures need to select CONFIG_ARCH_WANTS_PRE_LINK_VMLINUX and must
provide arch/<arch>/tools/Makefile with .arch.vmlinux.o target, which
will be invoked prior to the final vmlinux link step.

Some old versions of `rustc` did not report the LLVM version without
the patch version, e.g.:
$ rustc --version --verbose
rustc 1.48.0 (7eac88abb 2020-11-16)
binary: rustc
commit-hash: 7eac88abb2e57e752f3302f02be5f3ce3d7adfb4
commit-date: 2020-11-16
host: x86_64-unknown-linux-gnu
release: 1.48.0
LLVM version: 11.0
Which would make the new `scripts/rustc-llvm-version.sh` fail and,
in turn, the build:
$ make LLVM=1
SYNC include/config/auto.conf.cmd
./scripts/rustc-llvm-version.sh: 13: arithmetic expression: expecting primary: "10000 * 10 + 100 * 0 + "
init/Kconfig:83: syntax error
init/Kconfig:83: invalid statement
make[3]: *** [scripts/kconfig/Makefile:85: syncconfig] Error 1
make[2]: *** [Makefile:679: syncconfig] Error 2
make[1]: *** [/home/cam/linux/Makefile:780: include/config/auto.conf.cmd] Error 2
make: *** [Makefile:224: __sub-make] Error 2
Since we do not need to support such binaries, we can avoid adding logic
for computing `rustc`'s LLVM version for those old binaries.
Thus, instead, just make the match stricter.
Other `rustc` binaries (even newer) did not report the LLVM version at
all, but that was fine, since it would not match "LLVM", e.g.:
$ rustc --version --verbose
rustc 1.49.0 (e1884a8e3 2020-12-29)
binary: rustc
commit-hash: e1884a8e3c3e813aada8254edfa120e85bf5ffca
