If there is no System.map file for "make modules_install", scripts/depmod.sh will silently exit with success, having done nothing. Since this is an unexpected situation, change it to report a Warning for the missing file. The behavior is not changed except for the Warning message. The (previous) silent success and new Warning can be reproduced by: $ make mrproper; make defconfig $ make modules; make modules_install and since System.map is produced by "make vmlinux", the steps above omit producing the System.map file.

__ro_after_init is a specific __attribute__ that checkpatch does currently
not understand.
Add it to the known $Attribute types so that code that uses variables
declared with __ro_after_init are not thought to be a modifier type.
This appears as a defect in checkpatch output of code like:
static bool trust_cpu __ro_after_init = IS_ENABLED(CONFIG_RANDOM_TRUST_CPU);
[...]
if (trust_cpu && arch_init) {
where checkpatch reports:
ERROR: space prohibited after that '&&' (ctx:WxW)
if (trust_cpu && arch_init) {

When $DEPMOD is not found, only print a warning instead of exiting
with an error message and error status:
Warning: 'make modules_install' requires /sbin/depmod. Please install it.
This is probably in the kmod package.
Change the Error to a Warning because "not all build hosts for cross
compiling Linux are Linux systems and are able to provide a working
port of depmod, especially at the file patch /sbin/depmod."
I.e., "make modules_install" may be used to copy/install the
loadable modules files to a target directory on a build system and
then transferred to an embedded device where /sbin/depmod is run
instead of it being run on the build system.

Meelis Roos reported a {menu,n}config regression:
"I have libncurses devel package installed in the default system
location (as do 99%+ on actual developers probably) and in this
case, pkg-config is useless. pkg-config is needed only when
libraries and headers are installed in non-default locations but
it is bad to require installation of pkg-config on all the machines
where make menuconfig would be possibly run."
For {menu,n}config, do not use pkg-config if it is not installed.
For {g,x}config, keep checking pkg-config since we really rely on it
for finding the installation paths of the required packages.

Pull x86 fixes from Thomas Gleixner:
"Speculation:
- Make the microcode check more robust
- Make the L1TF memory limit depend on the internal cache physical
address space and not on the CPUID advertised physical address
space, which might be significantly smaller. This avoids disabling
L1TF on machines which utilize the full physical address space.
- Fix the GDT mapping for EFI calls on 32bit PTI
- Fix the MCE nospec implementation to prevent #GP
Fixes and robustness:
- Use the proper operand order for LSL in the VDSO
- Prevent NMI uaccess race against CR3 switching
- Add a lockdep check to verify that text_mutex is held in
text_poke() functions
- Repair the fallout of giving native_restore_fl() a prototype
- Prevent kernel memory dumps based on usermode RIP
- Wipe KASAN shadow stack before rewinding the stack to prevent false
positives
- Move the AMS GOTO enforcement to the actual build stage to allow
user API header extraction without a compiler
- Fix a section mismatch introduced by the on demand VDSO mapping

Prior to doing compiler feature detection in Kconfig, attempts to build GCC plugins with Clang would fail the build, much in the same way missing GCC plugin headers would fail the build.

checkpatch uses the in-kernel script spdxcheck.py to validate the specific license in a file or script. This check can currently fail for a couple reasons: o spdxcheck.py assumes the existence of git tree that may not exist for a bare source tree from something like a tarball o the spdxcheck.py must be run from the top level root directory So add a git existence test and set the subprocess subdirectory.

The current krealloc test does not function correctly when the temporary pointer return name contains the original pointer name. Fix that by maximally matching the return pointer name and the original pointer name and doing a separate comparison of the both names.

checkpatch repeatedly uses a runtime minimum version check that validates the minimum perl version required for a regex match by using a "$^V ge 5.10.0" runtime string match. Only perform that minimum version test once and store the result to reduce string matching time. This reduces runtime execution time for patches or files with high line counts. An example runtime improvement: new: $ time ./scripts/checkpatch.pl -f drivers/net/ethernet/intel/i40e/i40e_main.c > /dev/null real 0m11.856s user 0m11.831s sys 0m0.025s old: $ time ./scripts/checkpatch.pl -f drivers/net/ethernet/intel/i40e/i40e_main.c > /dev/null real 0m13.330s user 0m13.282s sys 0m0.049s Link: http://lkml.kernel.org/r/db21aa9703833bad65ab70cc4e8a78da5b399138.camel@perches.com Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

A struct with a bool member can have different sizes on various architectures because neither bool size nor alignment is standardized. So emit a message on the use of bool in structs only in .h files and not .c files. There is the real possibility that this test could have a false positive when a bool is declared as an automatic, so limit the test to .h files where the only false positive is for declarations in static inline functions.

Some LANG values (e.g. pl_PL.UTF-8) cause the sort command to output files before their parent directories, which makes them inaccessible for the kernel. In other words, when the kernel populates the rootfs, it is unable to create files whose parent directories have not been yet created. This patch makes sorting use the default (LANG=C) locale, which results in correctly laid out initramfs images (parent directories before files).

This commit improves the messages of the recursive dependency.
Currently, sym->dir_dep.expr is not checked. Hence, any dependency
in property visibility is regarded as the dependency of the symbol.
[Test Code 1]
config A
bool "a"
depends on B
config B
bool "b"
depends on A
[Test Code 2]
config A
bool "a" if B
config B
bool "b"
depends on A
For both cases above, the same message is displayed:
symbol B depends on A
symbol A depends on B
This commit changes the message for the latter, like this:
symbol B depends on A
symbol A prompt is visible depending on B
Also, 'select' and 'imply' are distinguished.

Currently, Kconfig does not complain about the recursive dependency
where 'imply' keywords are involved.
[Test Code]
config A
bool "a"
config B
bool "b"
imply A
depends on A
In the code above, Kconfig cannot calculate the symbol values correctly
due to the circular dependency. For example, allyesconfig followed by
syncconfig results in an odd behavior because CONFIG_B becomes visible
in syncconfig.
$ make allyesconfig
scripts/kconfig/conf --allyesconfig Kconfig
#
# configuration written to .config
#
$ cat .config
#
# Automatically generated file; DO NOT EDIT.
# Main menu
#
CONFIG_A=y
$ make syncconfig
scripts/kconfig/conf --syncconfig Kconfig
*
* Restart config...
*
*
* Main menu
*
a (A) [Y/n/?] y
b (B) [N/y/?] (NEW)
To detect this correctly, sym_check_expr_deps() should recurse to
not only sym->rev_dep.expr but also sym->implied.expr .
At this moment, sym_check_print_recursive() cannot distinguish
'select' and 'imply' since it does not know the precise context
where the recursive dependency has been hit. This will be solved
by the next commit.
In fact, even the document and the unit-test are confused. Using
'imply' does not solve recursive dependency since 'imply' addresses
the unmet direct dependency, which 'select' could cause.

Originally, recursive dependency was a fatal error for Kconfig
because Kconfig cannot compute symbol values in such a situation.

It is tedious to specify extra compiler options for every file. HOST_EXTRACFLAGS is useful to add options to all files in a directory. -I$(src)/libfdt is needed for all the files in this directory to include libfdt_env.h etc. from scripts/dtc/libfdt/. On the other hand, -I$(src) is used to include check-in headers from generated C files. Thus, I added it only to dtc-lexer.lex.o and dtc-parser.tab.o .

- Restructure of lockdep and latency tracers
This is the biggest change. Joel Fernandes restructured the hooks
from irqs and preemption disabling and enabling. He got rid of
a lot of the preprocessor #ifdef mess that they caused.
He turned both lockdep and the latency tracers to use trace events
inserted in the preempt/irqs disabling paths. But unfortunately,
these started to cause issues in corner cases. Thus, parts of the
code was reverted back to where lockde and the latency tracers
just get called directly (without using the trace events).
But because the original change cleaned up the code very nicely
we kept that, as well as the trace events for preempt and irqs
disabling, but they are limited to not being called in NMIs.
- Have trace events use SRCU for "rcu idle" calls. This was required
for the preempt/irqs off trace events. But it also had to not
allow them to be called in NMI context. Waiting till Paul makes
an NMI safe SRCU API.
- New notrace SRCU API to allow trace events to use SRCU.
- Addition of mcount-nop option support
- SPDX headers replacing GPL templates.
- Various other fixes and clean ups.
- Some fixes are marked for stable, but were not fully tested
before the merge window opened.
