- Remove potentially incomplete targets when Kbuid is interrupted by SIGINT etc. in case GNU Make may miss to do that when stderr is piped to another program. - Rewrite the single target build so it works more correctly. - Fix rpm-pkg builds with V=1. - List top-level subdirectories in ./Kbuild. - Ignore auto-generated __kstrtab_* and __kstrtabns_* symbols in kallsyms. - Avoid two different modules in lib/zstd/ having shared code, which potentially causes building the common code as build-in and modular back-and-forth. - Unify two modpost invocations to optimize the build process. - Remove head-y syntax in favor of linker scripts for placing particular sections in the head of vmlinux. - Bump the minimal GNU Make version to 3.82. - Clean up misc Makefiles and scripts. -----BEGIN PGP SIGNATURE----- iQJJBAABCgAzFiEEbmPs18K1szRHjPqEPYsBB53g2wYFAmM+4vcVHG1hc2FoaXJv eUBrZXJuZWwub3JnAAoJED2LAQed4NsGY2IQAInr0JUNnkkxwUSXtOcQuA3IK8RJ FbU9HXJRoV9H+7+l3SMlN7mIbrs5eE5fTY3iwQ3CVe139d1+1q7nvTMRv8owywJx GBgzswncuu1lk7iQQ//CxiqMwSCG8GJdYn1uDVy4I5jg3o+DtFZJtyq2Wb7pqsMm ZhZ4PozRN+idYQJSF6Vx/zEVLHI7quMBwfe4CME8/0Kg2+hnYzbXV/aUf0ED2emq zdCMDQgIOK5AhY+8qgMXKYnBUJMTqBp6LoR4p3ApfUkwRFY0sGa0/LK3U/B22OE7 uWyR4fCUExGyerlcHEVev+9eBfmsLLPyqlchNwpSDOPf5OSdnKmgqJEBR/Cvx0eh URerPk7EHxyH3G8yi+cU2GtofNTGc5RHPRgJE2ADsQEi5TAUKGmbXMlsFRL/51Vn lTANZObBNa1d4enljF6TfTL5nuccOa+DKvXnH9fQ49t0QdtSikv6J/lGwilwm1Sr BctmCsySPuURZfkpI9OQnLuouloMXl9f7Q/+S39haS/tSgvPpyITyO71nxDnXn/s BbFObZJUk9QkqOACjBP1hNErTLt83uBxQ9z+rDCw/SbLIe4nw0wyneuygfHI5rI8 3RZB2DbGauuJHX2Zs6YGS14SLSY33IsLqKR1/Vy3LrPvOHuEvNiOR8LITq5E0YCK OffK2Y5cIlXR0QWf =DHiN -----END PGP SIGNATURE----- Merge tag 'kbuild-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild Pull Kbuild updates from Masahiro Yamada: - Remove potentially incomplete targets when Kbuid is interrupted by SIGINT etc in case GNU Make may miss to do that when stderr is piped to another program. - Rewrite the single target build so it works more correctly. - Fix rpm-pkg builds with V=1. - List top-level subdirectories in ./Kbuild. - Ignore auto-generated __kstrtab_* and __kstrtabns_* symbols in kallsyms. - Avoid two different modules in lib/zstd/ having shared code, which potentially causes building the common code as build-in and modular back-and-forth. - Unify two modpost invocations to optimize the build process. - Remove head-y syntax in favor of linker scripts for placing particular sections in the head of vmlinux. - Bump the minimal GNU Make version to 3.82. - Clean up misc Makefiles and scripts. * tag 'kbuild-v6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild: (41 commits) docs: bump minimal GNU Make version to 3.82 ia64: simplify esi object addition in Makefile Revert "kbuild: Check if linker supports the -X option" kbuild: rebuild .vmlinux.export.o when its prerequisite is updated kbuild: move modules.builtin(.modinfo) rules to Makefile.vmlinux_o zstd: Fixing mixed module-builtin objects kallsyms: ignore __kstrtab_* and __kstrtabns_* symbols kallsyms: take the input file instead of reading stdin kallsyms: drop duplicated ignore patterns from kallsyms.c kbuild: reuse mksysmap output for kallsyms mksysmap: update comment about __crc_* kbuild: remove head-y syntax kbuild: use obj-y instead extra-y for objects placed at the head kbuild: hide error checker logs for V=1 builds kbuild: re-run modpost when it is updated kbuild: unify two modpost invocations kbuild: move vmlinux.o rule to the top Makefile kbuild: move .vmlinux.objs rule to Makefile.modpost kbuild: list sub-directories in ./Kbuild Makefile.compiler: replace cc-ifversion with compiler-specific macros ...
