* gcc-9: silence 'address-of-packed-member' warningSascha Hauer2019-09-121-0/+2
| | | | | | | | As done in the Linux Kernel. Most of the packed structures we have are optimized to not generate any unaligned accesses, so this warning produces a lot of false positives which are hard to fix in the code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * common: add generic CONFIG_UBSAN plumbingAhmad Fatoum2019-09-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | -fsanitize=undefined allows compile-time instrumentation of code to detect some classes of runtime undefined behavior. In preparation for allowing arches to provide infrastructure in support of this feature, add some generic UBSAN options and associated plumbing. These are only shown in the debug menu when the arch selects the appropriate symbol. The option is named equally to their Linux counterparts.

* kbuild: use -fmacro-prefix-map to make __FILE__ a relative pathMasahiro Yamada2019-08-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linux commit a73619a845d5625079cc1b3b820f44c899618388 The __FILE__ macro is used everywhere in the kernel to locate the file printing the log message, such as WARN_ON(), etc. If the kernel is built out of tree, this can be a long absolute path, like this: WARNING: CPU: 1 PID: 1 at /path/to/build/directory/arch/arm64/kernel/foo.c:... This is because Kbuild runs in the objtree instead of the srctree, then __FILE__ is expanded to a file path prefixed with $(srctree)/. Commit 9da0763bdd82 ("kbuild: Use relative path when building in a subdir of the source tree") improved this to some extent; $(srctree) becomes ".." if the objtree is a child of the srctree. For other cases of out-of-tree build, __FILE__ is still the absolute path. It also means the kernel image depends on where it was built. A brand-new option from GCC, -fmacro-prefix-map, solves this problem. If your compiler supports it, __FILE__ is the relative path from the srctree regardless of O= option. This provides more readable log and more reproducible builds. Please note __FILE__ is always an absolute path for external modules.

| * kconfig: update to Linux 5.2-rc4Masahiro Yamada2019-06-191-17/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous sync was Linux 4.20. This updates Kconfig to Linux 5.2-rc4. I adjusted the top Makefile as well because Linux commit 058507195b53 ("kbuild: move ".config not found!" message from Kconfig to Makefile") moved the .config check from Kconfig to Makefile. I also made auto.conf a mandatory include file, and remove it from the prerequisites of other targets. We are safe because Make is immediately terminated when syncconfig fails to generate auto.conf. Highlights: - The parser has no more shift/reduce conflicts - The lexer was rewritten more simply - The token lookup table was deleted - Replace license boilerplates with SPDX - Compile C files as separate units - Do not overwrite .config when the content was not changed - Lots of bug-fixes and cleanups Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Some commits were applied on top of that since then, but equivalent fixups were done in Linux. So, this commit overwrites everything scripts/kconfig/ with the one from Linux 4.20 Highlights: - 'silentoldconfig' has been renamed to 'syncconfig' (the top Makefile needs to be adjusted) - 'testconfig' target has been added for unit-tests (the top Makefile needs to export PYTHON3 because the test frame relies on Python3 and pytest) - The perfect hash table generated by gperf has been removed - The localization support has been removed - The 'option env=VAR' has been replaced with more generic variable reference syntax $(VAR) (./Kconfig and common/Kconfig need to be adjusted) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * kbuild: generate lexer and parser during build instead of shippingMasahiro Yamada2019-01-031-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent kernel versions run flex and bison to generate lexers and parsers from real source files such as *.l and *.y . This provides better maintainability than version-controlling pre-generated C files with a "_shipped" suffix. This commit imports flex and bison rules from Linux, and deletes pre-generated parsers and lexers. Refer to the following commits in Linux: - 033dba2ec06c ("kbuild: prepare to remove C files pre-generated by flex and bison") - 29c833061c1d ("kconfig: generate lexer and parser during build instead of shipping") - e039139be8c2 ("scripts/dtc: generate lexer and parser during build instead of shipping") Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * kbuild: clean up *.lex.c and *.tab.[ch] patterns from top-level MakefileMasahiro Yamada2019-01-031-0/+1

Clean them up globally from the top Makefile. Some of the final host programs those lexer/parser are linked into are necessary for building external modules, but the intermediates are unneeded. They can be cleaned away by 'make clean' instead of 'make mrproper'. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | -Wmissing-prototypes is a useful warning, so add it to the build. With this we can detect conflicting function prototypes. When a file implements a function but doesn't include the header file which provides the prototype for it then conflicting prototypes would go unnoticed without this warning. MIPS already had that warning, so we can remove it from the MIPS Makefile. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
