"dict.has_key(key)" on dictionaries has been replaced with "key in
dict". Additionally, when run under Python 3 some files don't decode
with the default encoding (tested with UTF-8). To handle that, don't
open the file in text mode and decode text line-by-line, ignoring
encoding errors.
This remains compatible with Python 2 and should have no functional
change.

Depending on how old your -next tree is, it may not have a master that
has the LICENSES directory.
Change the lookup to HEAD and find whatever LICENSE directory files are
used in that branch.
Miscellanea:
- Remove the checkpatch test as it will have its own SPDX license
identifier.

The rule of mainmenu_stmt does not have debug print of zconf_lineno(),
but if it had, it would print a wrong line number for the same reason
as commit b2d00d7c61c8 ("kconfig: fix line numbers for if-entries in
menu tree").
The mainmenu_stmt does not need to eat following empty lines because
they are reduced to common_stmt.

The files auto.conf and tristate.conf are mandatory for building
modules.builtin files, therefore include them as such.
Usually, the top-level Makefile ensures that those files exist but we
want to make sure we get noticed if they are missing for whatever
reason.

If Make gets a fatal signal while a shell is executing, it may delete
the target file that the recipe was supposed to update. This is needed
to make sure that it is remade from scratch when Make is next run; if
Make is interrupted after the recipe has begun to write the target file,
it results in an incomplete file whose time stamp is newer than that
of the prerequisites files. Make automatically deletes the incomplete
file on interrupt unless the target is marked .PRECIOUS.
The situation is just the same as when the shell fails for some reasons.
Usually when a recipe line fails, if it has changed the target file at
all, the file is corrupted, or at least it is not completely updated.
Yet the file’s time stamp says that it is now up to date, so the next
time Make runs, it will not try to update that file.
However, Make does not cater to delete the incomplete target file in
this case. We need to add .DELETE_ON_ERROR somewhere in the Makefile
to request it.
scripts/Kbuild.include seems a suitable place to add it because it is
included from almost all sub-makes.
Please note .DELETE_ON_ERROR is not effective for phony targets.
The external module building should never ever touch the kernel tree.
The following recipe fails if include/generated/autoconf.h is missing.
However, include/config/auto.conf is not deleted since it is a phony
target.
PHONY += include/config/auto.conf
include/config/auto.conf:
$(Q)test -e include/generated/autoconf.h -a -e $@ || ( \
echo >&2; \
echo >&2 " ERROR: Kernel configuration is invalid."; \
echo >&2 " include/generated/autoconf.h or $@ are missing.";\
echo >&2 " Run 'make oldconfig && make prepare' on kernel src to fix it."; \
echo >&2 ; \
/bin/false)

Currently, only syncconfig creates or updates include/config/auto.conf
and some other files. Other config targets create or update only the
.config file.
When you configure and build the kernel from a pristine source tree,
any config target is followed by syncconfig in the build stage since
include/config/auto.conf is missing.
We are moving compiler tests from Makefile to Kconfig. It means that
parsing Kconfig files will be more costly since Kconfig invokes the
compiler commands internally. Thus, we want to avoid invoking Kconfig
twice (one for *config to create the .config, and one for syncconfig
to synchronize the auto.conf). If auto.conf does not exist, we can
generate all configuration files in the first configuration stage,
which will save the syncconfig in the build stage.
Please note this should be done only when auto.conf is missing. If
*config blindly did this, time stamp files under include/config/ would
be unnecessarily touched, triggering unneeded rebuild of objects.
I assume a scenario like this:
1. You have a source tree that has already been built
with CONFIG_FOO disabled
2. Run "make menuconfig" to enable CONFIG_FOO
3. CONFIG_FOO turns out to be unnecessary.
Run "make menuconfig" again to disable CONFIG_FOO
4. Run "make"
In this case, include/config/foo.h should not be touched since there
is no change in CONFIG_FOO. The sync process should be delayed until
the user really attempts to build the kernel.
This commit has another motivation; I want to suppress the 'No such
file or directory' warning from the 'include' directive.
The top-level Makefile includes auto.conf with '-include' directive,
like this:
ifeq ($(dot-config),1)
-include include/config/auto.conf
endif
This looks strange because auto.conf is mandatory when dot-config is 1.
I guess only the reason of using '-include' is to suppress the warning
'include/config/auto.conf: No such file or directory' when building
from a clean tree. However, this has a side-effect; Make considers
the files included by '-include' are optional. Hence, Make continues
to build even if it fails to generate include/config/auto.conf. I will
change this in the next commit, but the warning message is annoying.
(At least, kbuild test robot reports it as a regression.)
With this commit, Kconfig will generate all configuration files together
with the .config and I guess it is a solution good enough to suppress
the warning.
Note:
GNU Make 4.2 or later does not display the warning from the 'include'
directive if include files are successfully generated. See GNU Make
commit 87a5f98d248f ("[SV 102] Don't show unnecessary include file
errors.") However, older GNU Make versions are still widely used.

syncconfig updates the .config only when sym_change_count > 0, i.e.
any change in config symbols has been detected.
Not only symbols but also comments are contained in the .config file.
If only comments are updated, they are not fed back to the .config,
then the stale comments are left-over. Of course, this is just a
matter of comments, but why not fix it.
I see some scenarios where this happens.
Scenario A:
1. You have a source tree that has already been configured.
2. Linus increments the version number in the top-level Makefile
(i.e. he commits a new release)
3. You pull it, and run 'make'
4. syncconfig is invoked because the environment variable,
KERNELVERSION is updated, but the .config is not updated since
no config symbol is changed.
5. The .config file contains a kernel version in the top line:
# Automatically generated file; DO NOT EDIT.
# Linux/arm64 4.18.0-rc2 Kernel Configuration
... which points to a previous version.
Scenario B:
1. You have a source tree that has already been configured.
2. You upgrade the compiler, but it still has the same version number.
This may happen if you regularly build the latest compiler from
the source code.
3. You run 'make'
4. syncconfig is invoked because the environment variable,
CC_VERSION_TEXT is updated, but the .config is not updated since
no config symbol is changed.
5. The .config file contains the version string of the compiler:
#
# Compiler: aarch64-linux-gcc (GCC) 9.0.0 20180628 (experimental)
#
... which carries the information of the old compiler.
If KCONFIG_NOSILENTUPDATE is set, syncconfig is not allowed to update
the .config file. Otherwise, it is fine to update it regardless of
sym_change_count.

'make syncconfig' creates some files such as include/config/auto.conf,
include/generate/autoconf.h, etc. but the necessary directory creation
relies on scripts/kconfig/Makefile.
To make Kconfig self-contained, create directories as needed in
conf_write_autoconf().
This change allows scripts/kconfig/Makefile cleanups; syncconfig can
be merged into simple-targets.

Commit 17263baf958b ("kconfig: Create include/generated for

ran streamline_config.pl followed by silentoldconfig at that time.
Since commit 81d2bc227305 ("kconfig: invoke oldconfig instead of
silentoldconfig from local*config"), no sub-directory is required.

file_write_dep() is called only from conf_write_autoconf().

Over time, the use of the flag SYMBOL_AUTO changed from initially
marking three automatically generated symbols ARCH, KERNELRELEASE and
UNAME_RELEASE to today's effect of protecting symbols from being
written out.
Currently, only symbols of type CHOICE and those with option
defconf_list set have that flag set.
Reflect that change in semantics in the flag's name.

Each of 'make {menu,n,g,x}config' uses (needs) pkg-config to make sure
that other required files are present and to determine build flags
settings, but none of these check that pkg-config itself is present.
Add a check for all 4 of these targets and update
Documentation/process/changes.rst to mention 'pkg-config'.

If coccicheck fails, it should return an error code distinct from zero
to signal about an internal problem. Current code instead of exiting with
the tool's error code returns the error code of 'echo "coccicheck failed"'
which is almost always equals to zero, thus failing the original intention
of alerting about a problem. This patch fixes the code.

We currently use dpkg --print-architecture, which reports the
architecture of the build machine. We can make a better guess
than this by asking dpkg-architecture what the host architecture,
i.e. the default architecture for building packages, is. This is
sensitive to environment variables such as CC and DEB_HOST_ARCH,
which should already be set in a cross-build environment.

If KBUILD_DEBARCH is set then we will not use the result of
architecture detection, and we may also warn unnecessarily.
Move the check for KBUILD_DEBARCH further up to avoid this.

Currently, filechk unconditionally opens the first prerequisite and
redirects it as the stdin of a filechk_* rule. Hence, every target
using $(call filechk,...) must list something as the first prerequisite
even if it is unneeded.
'< $<' is actually unneeded in most cases. Each rule can explicitly
adds it if necessary.

In Fedora, the debug information is packaged separately (foo-debuginfo) and
can be installed separately. There's been a long standing issue where only
one version of a debuginfo info package can be installed at a time. There's
been an effort for Fedora for parallel debuginfo to rectify this problem.
Part of the requirement to allow parallel debuginfo to work is that build ids
are unique between builds. The existing upstream rpm implementation ensures
this by re-calculating the build-id using the version and release as a
seed. This doesn't work 100% for the kernel because of the vDSO which is
its own binary and doesn't get updated when embedded.
Fix this by adding some data in an ELF note for both the kernel and modules.
The data is controlled via a Kconfig option so distributions can set it
to an appropriate value to ensure uniqueness between builds.

Commit 8370edea81e3 ("bin2c: move bin2c in scripts/basic") moved bin2c
to the scripts/basic/ directory, incorrectly stating "Kexec wants to
use bin2c and it wants to use it really early in the build process.
See arch/x86/purgatory/ code in later patches."
Commit bdab125c9301 ("Revert "kexec/purgatory: Add clean-up for
purgatory directory"") and commit d6605b6bbee8 ("x86/build: Remove
unnecessary preparation for purgatory") removed the redundant
purgatory build magic entirely.
That means that the move of bin2c was unnecessary in the first place.
fixdep is the only host program that deserves to sit in the
scripts/basic/ directory.

The layout of Makefile.gcc-plugins had uneven tabs, and the long names
of things made this file a bit hard to quickly visually parse. This
breaks lines and moves options to the same tab depth. While we're at
it, this also adds some comments about the various sections.
