I am sending this a bit earlier. Please pull it in when you open the merge window. Thanks. The following changes since commit d45331b00ddb179e291766617259261c112db872: Linux 5.3-rc4 (2019-08-11 13:26:41 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git tags/kbuild-v5.4 for you to fetch changes up to 77564a4829ef6d309331d443ea6ceb065f3dc371: genksyms: convert to SPDX License Identifier for lex.l and parse.y (2019-09-14 11:40:13 +0900) ---------------------------------------------------------------- Kbuild updates for v5.4 - add modpost warn exported symbols marked as 'static' because 'static' and EXPORT_SYMBOL is an odd combination - break the build early if gold linker is used - optimize the Bison rule to produce .c and .h files by a single pattern rule - handle PREEMPT_RT in the module vermagic and UTS_VERSION - warn CONFIG options leaked to the user-space except existing ones - make single targets work properly - rebuild modules when module linker scripts are updated - split the module final link stage into scripts/Makefile.modfinal - fix the missed error code in merge_config.sh - improve the error message displayed on the attempt of the O= build in unclean source tree - remove 'clean-dirs' syntax - disable -Wimplicit-fallthrough warning for Clang - add CONFIG_CC_OPTIMIZE_FOR_SIZE_O3 for ARC - remove ARCH_{CPP,A,C}FLAGS variables - add $(BASH) to run bash scripts - change *CFLAGS_.o to take the relative path to $(obj) instead of the basename - stop suppressing Clang's -Wunused-function warnings when W=1 - fix linux/export.h to avoid genksyms calculating CRC of trimmed exported symbols - misc cleanups ---------------------------------------------------------------- Denis Efremov (2): modpost: check for static EXPORT_SYMBOL* functions modpost: add NOFAIL to strndup Guillaume Tucker (1): merge_config.sh: ignore unwanted grep errors Heikki Krogerus (1): modpost: add guid_t type definition Kees Cook (1): kbuild: Parameterize kallsyms generation and correct reporting Mark Brown (1): merge_config.sh: Check error codes from make Masahiro Yamada (54): kbuild: use $(basename ...) for cmd_asn1_compiler kbuild: make bison create C file and header in a single pattern rule kbuild: move flex and bison rules to Makefile.host kbuild: add [M] marker for build log of *.mod.o kbuild: treat an object as multi-used when $(foo-) is set kbuild: move the Module.symvers check for external module build kbuild: refactor part-of-module more kbuild: fix modkern_aflags implementation kbuild: remove 'make /' support kbuild: remove meaningless 'targets' in ./Kbuild kbuild: do not descend to ./Kbuild when cleaning kbuild: unset variables in top Makefile instead of setting 0 kbuild: unify vmlinux-dirs and module-dirs rules kbuild: unify clean-dirs rule for in-kernel and external module kbuild: re-implement detection of CONFIG options leaked to user-space kbuild: make single targets work more correctly treewide: remove dummy Makefiles for single targets kbuild: move KBUILD_LDS, KBUILD_VMLINUX_{OBJS,LIBS} to makefiles.rst kbuild: rebuild modules when module linker scripts are updated kbuild: split final module linking out into Makefile.modfinal .gitignore: ignore modules.order explicitly kbuild: add CONFIG_ASM_MODVERSIONS kbuild: move modkern_{c,a}flags to Makefile.lib from Makefile.build kbuild: pkg: clean up package files/dirs from the top Makefile kbuild: pkg: add package targets to PHONY instead of FORCE kbuild: pkg: rename scripts/package/Makefile to scripts/Makefile.package kbuild: remove unneeded '+' marker from kselftest-merge docs: kbuild: fix invalid ReST syntax docs: kbuild: remove cc-ldoption from document again init/Kconfig: rework help of CONFIG_CC_OPTIMIZE_FOR_SIZE kbuild: remove unneeded comments and code from scripts/basic/Makefile kbuild: remove unneeded dependency for $(DOC_TARGETS) kbuild: get rid of $(realpath ...) from scripts/mkmakefile kbuild: remove 'Using ... as source for kernel' message kbuild: Inform user to pass ARCH= for make mrproper only when necessary kbuild: clarify where to run make mrproper when out-of-tree fails kbuild: move the clean srctree check to the outputmakefile target kbuild: remove prepare3 target kbuild: check clean srctree even earlier kbuild: remove clean-dirs syntax kbuild: remove unneeded '+' marker from cmd_clean kbuild: clean up subdir-ymn calculation in Makefile.clean kbuild,arc: add CONFIG_CC_OPTIMIZE_FOR_PERFORMANCE_O3 for ARC kbuild: remove ARCH_{CPP,A,C}FLAGS kbuild: add $(BASH) to run scripts with bash-extension kbuild: change *FLAGS_.o to take the path relative to $(obj) kbuild: refactor scripts/Makefile.extrawarn kbuild: rename KBUILD_ENABLE_EXTRA_GCC_CHECKS to KBUILD_EXTRA_WARN kbuild: allow Clang to find unused static inline functions for W=1 build export.h: remove defined(__KERNEL__), which is no longer needed export.h, genksyms: do not make genksyms calculate CRC of trimmed symbols modpost: use MODULE_INFO() for __module_depends modpost: use __section in the output to *.mod.c genksyms: convert to SPDX License Identifier for lex.l and parse.y Nathan Chancellor (1): kbuild: Do not enable -Wimplicit-fallthrough for clang for now Thomas Gleixner (2): kbuild: Fail if gold linker is detected Kbuild: Handle PREEMPT_RT for version string and magic .gitignore | 2 +- Documentation/kbuild/kbuild.rst | 28 +-- Documentation/kbuild/makefiles.rst | 67 +++--- Kbuild | 7 -
