[Build system] - add CONFIG_UNUSED_KSYMS_WHITELIST, which will be useful to define a fixed set of export symbols for Generic Kernel Image (GKI) - allow to run 'make dt_binding_check' without .config - use full schema for checking DT examples in *.yaml files - make modpost fail for missing MODULE_IMPORT_NS(), which makes more sense because we know the produced modules are never loadable - Remove unused 'AS' variable [Kconfig] - sanitize DEFCONFIG_LIST, and remove ARCH_DEFCONFIG from Kconfig files - relax the 'imply' behavior so that symbols implied by y can become m - make 'imply' obey 'depends on' in order to make 'imply' really weak [Misc] - add documentation on building the kernel with Clang/LLVM - revive __HAVE_ARCH_STRLEN for 32bit sparc to use optimized strlen() - fix warning from deb-pkg builds when CONFIG_DEBUG_INFO=n - various script and Makefile cleanups -----BEGIN PGP SIGNATURE----- iQJJBAABCgAzFiEEbmPs18K1szRHjPqEPYsBB53g2wYFAl6DbP8VHG1hc2FoaXJv eUBrZXJuZWwub3JnAAoJED2LAQed4NsGAfkQALZqMCqtX9cAJej04+lnBCzwVPep 6s8/s6vW6PF92sHv+SJtHvKSnDekcZT2xT8dkPDaVmuOye8xhENs5dFZ4tSKO5D0 F8YkkM17mu/cylNZ2UCy/8weh6/TjsD7pa+mFqWo/++30JiXm12v3mVFR568KPXI kFau/3ALvY1NIr2wUAI2SOd6A4v/Epzpk0ltnFg3f5iWVFKlE03MGueAF+YZzq7v UrU73HdUxF/SBW2Jz3UtV9XY8P38uQmmtoDE8SZikG4PjW03q9w6pnhntDBl/H2b dZFg40eG7SHXN4L+OOI32ae9jePHvKpsnjeaeNoT/DZpwpuuxXu7C2EmUy+wCAnM Rw4+kiAVNppRMRH1GTdp1XjLY6PwPqizzZGmufwX+W3MI8oZdlLSUJLbrO73P/aF QR3MgkJkjvgmRVPP9fr8SNcZ39tDGI4KqLdWvjVVSC/s86aDnw/34puEfw0lj4vs gCi923iJQ7Y/QWX63TYZhy96pnedlwE2s6aR1InVER3+XMH9K1nW34CDaKQsp1CB 6zyrd40+K5ETOKo3OAjq4FttlhRkEpX9nIsffCzOz6tybysHTSrCzYhfjpIAzzYj Et5HpXbegHShIqN44yqBumt6YkTZac6Aub9FzInW2LPzZgiofDaNesDQmnQmIZOa JlUyBrjXRfwkvCH0 =wT8A -----END PGP SIGNATURE----- Merge tag 'kbuild-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kbuild updates from Masahiro Yamada: "Build system: - add CONFIG_UNUSED_KSYMS_WHITELIST, which will be useful to define a fixed set of export symbols for Generic Kernel Image (GKI) - allow to run 'make dt_binding_check' without .config - use full schema for checking DT examples in *.yaml files - make modpost fail for missing MODULE_IMPORT_NS(), which makes more sense because we know the produced modules are never loadable - Remove unused 'AS' variable Kconfig: - sanitize DEFCONFIG_LIST, and remove ARCH_DEFCONFIG from Kconfig files - relax the 'imply' behavior so that symbols implied by 'y' can become 'm' - make 'imply' obey 'depends on' in order to make 'imply' really weak Misc: - add documentation on building the kernel with Clang/LLVM - revive __HAVE_ARCH_STRLEN for 32bit sparc to use optimized strlen() - fix warning from deb-pkg builds when CONFIG_DEBUG_INFO=n - various script and Makefile cleanups" * tag 'kbuild-v5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (34 commits) Makefile: Update kselftest help information kbuild: deb-pkg: fix warning when CONFIG_DEBUG_INFO is unset kbuild: add outputmakefile to no-dot-config-targets kbuild: remove AS variable net: wan: wanxl: refactor the firmware rebuild rule net: wan: wanxl: use $(M68KCC) instead of $(M68KAS) for rebuilding firmware net: wan: wanxl: use allow to pass CROSS_COMPILE_M68k for rebuilding firmware kbuild: add comment about grouped target kbuild: add -Wall to KBUILD_HOSTCXXFLAGS kconfig: remove unused variable in qconf.cc sparc: revive __HAVE_ARCH_STRLEN for 32bit sparc kbuild: refactor Makefile.dtbinst more kbuild: compute the dtbs_install destination more simply Makefile: disallow data races on gcc-10 as well kconfig: make 'imply' obey the direct dependency kconfig: allow symbols implied by y to become m net: drop_monitor: use IS_REACHABLE() to guard net_dm_hw_report() modpost: return error if module is missing ns imports and MODULE_ALLOW_MISSING_NAMESPACE_IMPORTS=n modpost: rework and consolidate logging interface kbuild: allow to run dt_binding_check without kernel configuration ...
