Kbuild updates for v5.2
- allow users to invoke 'make' out of the source tree - refactor scripts/mkmakefile - deprecate KBUILD_SRC, which was used to track the source tree location for O= build. - fix recordmcount.pl in case objdump output is localized - turn unresolved symbols in external modules to errors from warnings by default; pass KBUILD_MODPOST_WARN=1 to get them back to warnings - generate modules.builtin.modinfo to collect .modinfo data from built-in modules - misc Makefile cleanups -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJc0upmAAoJED2LAQed4NsGreoP/jkKQojVdzTjM/nn/Xe9FrE9 elQ59Wu/gW/q7jouN733WTJ2fRPAEVaGPw/CT/cCRWjNJjd6MM4voDKVxifZE+u4 qz5XUGq4Mjozd0MJdU1LA1dIRJrEaPofOj7E0JEIerEdLPKpv4kjCCbbHOZwN2Kl YrpPFJkYspCRVG+txEWY8YaZeU/+OAdNckJnMkX8hnUwsNplAlPw4L/5Y12Uncuz 7g/3T1f701pJhStoO4OPR/+Rivi0EX5AP7TZyv2/FOwTO+Oau5G1rF0j1BT0+ceg d+bApuaHLR4ocZ6GvWfACMYhH7ais0BUgAwi6HY/b78SGMmNB6xlD5biVqcklx6c mjrPNaj6WJEQIflZ3yr83tRNhTu7xXRKZkrGHHUjOGNsRULuD8RFrXtusl06A22S hA3vt2SF4FuLBabPw5yFkKNOTX+P5dG79BC1fWIQjglBGoYqWTRQNYoottr/7t2T Si+E6J2lAD0EDNuc/EFKWfrgONfatgcdgQuTibwCcE2KfYnMG/C+9DvxRV4lAQtn fYpap9gws+0AisbVx0m1W088NMFiwrMbN3n3KITGY/15XDmeySEA1QgPKFN8JHJd Do0duaMx8BHjkA5ms/Bf0AZd0tWUkWVdt0epwU2KafWNGK7VaPnhKxn5eQOGkWV+ gT3J3XZc3b7OEOQ4XX3Z =zj9w -----END PGP SIGNATURE----- Merge tag 'kbuild-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kbuild updates from Masahiro Yamada: - allow users to invoke 'make' out of the source tree - refactor scripts/mkmakefile - deprecate KBUILD_SRC, which was used to track the source tree location for O= build. - fix recordmcount.pl in case objdump output is localized - turn unresolved symbols in external modules to errors from warnings by default; pass KBUILD_MODPOST_WARN=1 to get them back to warnings - generate modules.builtin.modinfo to collect .modinfo data from built-in modules - misc Makefile cleanups * tag 'kbuild-v5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (21 commits) .gitignore: add more all*.config patterns moduleparam: Save information about built-in modules in separate file Remove MODULE_ALIAS() calls that take undefined macro .gitignore: add leading and trailing slashes to generated directories scripts/tags.sh: fix direct execution of scripts/tags.sh scripts: override locale from environment when running recordmcount.pl samples: kobject: allow CONFIG_SAMPLE_KOBJECT to become y samples: seccomp: turn CONFIG_SAMPLE_SECCOMP into a bool option kbuild: move Documentation to vmlinux-alldirs kbuild: move samples/ to KBUILD_VMLINUX_OBJS modpost: make KBUILD_MODPOST_WARN also configurable for external modules kbuild: check arch/$(SRCARCH)/include/generated before out-of-tree build kbuild: remove unneeded dependency for include/config/kernel.release memory: squash drivers/memory/Makefile.asm-offsets kbuild: use $(srctree) instead of KBUILD_SRC to check out-of-tree build kbuild: mkmakefile: generate a simple wrapper of top Makefile kbuild: mkmakefile: do not check the generated Makefile marker kbuild: allow Kbuild to start from any directory kbuild: pass $(MAKECMDGOALS) to sub-make as is kbuild: fix warning "overriding recipe for target 'Makefile'" ...
